DeviceMaster is not detected in the Driver in the MAC communication mode. This discussion references DeviceMaster’s running the following drivers and firmware. Windows Driver version 10.10 (which includes the Comtrol Driver Management Console) ftp:///dev_mstr/rts/drivers/win7/devicemaster_windows_10.10.exe SocketServer version 9.16ftp:///dev_mstr/rts/software/socketserver/socketserver-9.16.binBootloader 3.23ftp:///dev_mstr/rts/software/bootloader/bootloader-3.23.binPortVision DX versionftp:///dev_mstr/portvision_dx/portvision_dx_1.03.msiPrevious versions of all of the above are still valid, but some screen shots may be different and minor other differences may be experienced.The DeviceMaster Driver can communicate to the DeviceMaster hardware using one of two communications protocols. MAC mode (layer 2) and TCP/IP (layer 3). This document will attempt to describe and provide assistance when the Driver is unable to use the MAC mode of communications. If the Driver is unable to detect the DeviceMaster in the configuration from the drop down list for selecting the appropriate unit, then MAC mode will not work. Please note that only the model as shown in the name will be detectable. For example if you have a DeviceMaster RTS and installed the driver for a DeviceMaster PRO, the Driver will be unable to list the correct MAC addresses for the RTS model. This is also true when the wrong number of serial ports have been defined. There are several different instances in which the MAC mode of operation will not be possible and most will be described and in these cases using the IP mode will be required. There is no real disadvantage of using IP mode communications as opposed to the MAC mode communications in the Driver. In most cases this is only a matter of ease of total configuration.We will assume that the DeviceMaster is attached to the network and powered on and that all LED’s are indicating proper operation. The yellow Status/Power LED is on solid and blinks at 10 second intervals and the Ethernet LED’s are showing Link status.Here is an example of what the Comtrol Driver Management Console should show when MAC mode is selected and the drop down arrow to the right of the field is engaged.In this example the “03 DeviceMaster RTS 2 Port, DB9, 1E” model is selected in the left column.In the General Tab there are several different 2 port units listed. Any of these could be selected but in this example the last listing is the selected unit. The drop down list will always display the 00 C0 4E # # # as this is a dummy placeholder.If you are able to see some DeviceMaster units in this list, but not your specific DeviceMaster, then this document is not for you. This document is for the user that SHOULD see MAC listings but does not.There are some different conditions to be considered when opening the Comtrol Drivers Management Console and attempting to install the MAC address in the driver.Begin with PortVision DX.Is PortVision DX able to scan the network and discover the DeviceMaster?YES (PortVision DX does Scan and discover the DeviceMaster)1.Check that the correct model of DeviceMaster was installed in the Driver. If thewrong model was selected during installation (ex: you have a DeviceMasterRTS and installed the driver for a DeviceMaster PRO) the Driver will be unableto list the correct MAC addresses.2.Open the Local Area Connection Properties and check to see if theDeviceMaster NDIS Protocol in loaded and check marked. In most cases ifPortVision DX can scan and discover the DeviceMaster, then the Drivershould also be able to discover the DeviceMaster.It should look like this:If the protocol is not listed, manually install it byfollowing these steps:Click on the “I n stall..” button.Select “Protocol” and click the “A dd” button.Click the “Have Disk…” button.Click “Browse” and go to this folder:C:\Program Files\Comtrol\DeviceMaster\orC:\Program Files (x86)\Comtrol\DeviceMaster\Select any .inf file as the procedure will use theone that it needs.Click : “Open”Click “OK”In some cases a PC reboot may be required.detect the DeviceMaster, it is probable that the IP mode will be required in theDriver. In this circumstance it is likely that we will be unable to determine thecause of the failure of the NDIS protocol.NO (PortVision DX Scans, but does NOT discover the DeviceMaster)1. Check to see if a Firewall is installed and enabled. If it is, temporarily disablethe firewall and scan again. If the scan now discovers the DeviceMaster, youwill need to modify the firewall settings to allow traffic on port 4607. Thatprocedure will not be covered in this document.2.Is there a Router between the DeviceMaster and this PC? If there is, thenthe IP mode must be used as routers do not forward MAC packets and only dealwith TCP/IP.If PortVision DX is unable to discover the DeviceMaster, it is almost assured the Driver will be unable to discover and use the MAC mode. In this case, the DeviceMaster should be manually added to PortVision DX using the instructions found in the user guide. If the DeviceMaster is then seen to be operational in PortVision DX, the Driver will need to also be configured to use the IP Mode. If PortVision DX still cannot communicate to the DeviceMaster, then there are other possible causes.1.Ethernet cable connected to the wrong Ethernet port on the DeviceMaster2.No IP route to the DeviceMaster3.Improperly configured NIC4.Improperly configured NIC used in a Virtual Machine environment5.NAT not configured6.NIC’s Teamed with an option not supported by 3rd party protocols7.DeviceMaster routed through the wrong NIC in the PC8.3rd party application blocking Comtrol networking protocols9.Faulty DeviceMaster. Check with a different PC。

These communicationfaults could break the connection between DriveExecutive and the drive orbetween the controller and the drive. This anomaly would occur undercertain conditions and with certain configurations.DPI Port LockupWhen a Human Interface Module (HIM) was disconnected and reconnectedrepeatedly in a short period of time, the drive would experience a HIM Port0 error. This would make the HIM port non-functional.Fault Restart DisplayWhen executing an automatic restart after a fault, the drive would notcorrectly display the count down to the restart properly. It would correctlydisplay the tens digit, but it would not display the ones digit.The following table illustrates an example.Time Remaining (seconds)1211109876543210 How it should display countdown1211109876543210 How it did display countdown1_1_1_____________________Non Volatile Storage (NVS)Executing the homing function too frequently or changing certain parametervalues too frequently would cause the drive to stop operating (due to anF918-Control Task Overload, F919-System Task Overload or F920-5 msecTask Overload fault). The Human Interface Module (HIM) would display“Port 0 Comm Loss.” Recovery from this condition required cycling poweron the drive. After power was cycled, the drive would report a F101-PwrDnNVS Blank, F103-PwrDn NVS Incomp or F117-PwrDn NVS Chksm fault,and drive parameter values would be set to their default values.This occurred because the drive was attempting to write to NVS too quickly,and the requests for NVS writes were over-running the buffer for NVSwrites.The drive would attempt to write to NVS when executing the homingfunction. It would also write to NVS when certain parameters in the SpeedRegulator, Inertia Compensation and (Position) Torque Boost parametergroups were modified. Controlling these parameters via datalink couldcreate a situation where attempts to write to NVS would occur toofrequently.PowerFlex® 755 Drives (revision 2.006)15Option Card Version DisplayDisplay of firmware version for option modules on the Human Interface Module (HIM) or in configuration software (DriveExplorer, DriveExecutive or RSLogix 5000) would be incorrect.Port Loss Due to Lost Client Server MessageUnder certain conditions, a certain combination of DPI messages would lock up a DPI port.Position Feedback ErrorWhen using position control, the value of parameter 857 [Psn Fdbk] could be in error from the actual machine position by one encoder count. This could cause a final position error in your system.Position Torque Boost Coordinate OrderingThe drive would accept Position Torque Boost coordinates out of order. The values for parameters 1520 [PsnTrqBst Ps X1], 1521 [PsnTrqBst Ps X2], 1522 [PsnTrqBst Ps X3], 1523 [PsnTrqBst Ps X4] and 1524 [PsnTrqBst Ps X5] must be in ascending order. The older firmware revision would accept them if they were not in ascending order.Pump JackThe time interval used for calculations of the “virtual pump position” changed from 2 mS to 2.048 mS, which is the actual task interrupt time for the calculation.Sleep Wake ModeIf there was a Sleep Cfg alarm caused by the sleep level being higher than the wake level and the condition was corrected while the other permissives were present, the control would require one of the permissives to be reset for the drive to start.With the new firmware, permissives need not be reset for the drive to start.Interpolator Output UnstableWhen the drive was in Integrated Motion on EtherNet/IP (CIP Motion) mode and in a position control configuration, the output of the Velocity Interpolator would oscillate. This would cause poor performance in some position control applications that use Integrated Motion on EtherNet/IP (CIP Motion).Position Feedback RolloverWhen the drive was in Integrated Motion on EtherNet/IP (CIP Motion) mode and in a position control configuration, there could be a spike in torque output when the position feedback count rolled over.Publication 750-RN010B-EN-E – May 2012Supersedes Publication 750-RN010A-EN-E – January 2011Copyright © 2012 Rockwell Automation, Inc.

ITU-T G.984.4 (2008)/Amd.1 (06/2009) iFOREWORDThe International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.NOTEIn this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.As of the date of approval of this Recommendation, ITU had received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http://www.itu.int/ITU-T/ipr/.© ITU 2010All rights reserved.

The CMA consists of a main flameproof enclosure containing all of the electrical components and an attached smaller mechanical enclosure containing only gearing and mechanical power transfer devices. The Size 3 Actuators are available in three different functions: Linear, Quarter-turn, and Rotary. The Size 4& 5Actuators are available with Linear function only. The main enclosure is defined into “Sizes” per the table on the following page.The top part of the equipment is the flameproof “d” enclosure (the main enclosure), which is cylindrical in shape and includes a base and cover. The main enclosure is constructed out of the same aluminum either Low Pressure Gravity Cast (LPGC) or High Pressure Die Cast (HPDC). For Size 3 actuators, the cover has three different sizes: standard, intermediate and extended. For Size 4 & 5 actuators, there is one cover size. The enclosure houses a hand-knob which creates a cylindrical flamepath joint. The user may use the hand-knob to switch from manual to remote operation and control of the actuator. The cover forms a cylindrical flamepath joint with the base to which it is secured by fasteners. The joint is provided with suitable seals for environmental protection.The main enclosure houses all of the electronic components which make up the monitoring and control circuitry. This circuitry consists of power and logic PCBs both mounted on an aluminum bracket. The bracket is fastened to a cast aluminum mount which also acts as a mount for the DC motor. The whole assembly is fastened to the base. The operator uses an LCD display to program the actuator to control the motor and the logic PCB uses a feedback mechanism to sense the position of the output shaft. There are four ¾ NPT or M25 threaded entries to the enclosure for field wiring purposes.CML – Linear Compact Modulating ActuatorThe mechanical part of the linear enclosure is small in comparison to the main enclosure. This enclosure does not have any electrical components and contains mechanical components only. The enclosure houses a screw shaft which is driven by the DC motor. The shaft is supported by roller bearings and forms a flamepath through the enclosure. The shaft operates with a drive nut to provide the motion to the linear output shaft. The linear output shaft travels through a bronze bushing and into the hazardous area.This linear output shaft has two shoulder screws threaded into it at an angle perpendicular to the center line of the shaft. One screw is attached to a feedback shaft which penetrates into the electronics enclosure through a bronze bushing creating two flamepaths, one on either side of the bushing. Access to the shoulder screw is via an aluminum plate sealed from the environment. The other shoulder screw is tipped with an arrow to indicate the current position of the actuator to the user. The arrow can be seen through a window which is also sealed from the environment.The linear actuator is available in a low temperature variant which uses different seals to allow the equipment to be used in the lower minimum ambient temperature of -40°C.CMQ – Quarter-turn Compact Modulating ActuatorThe mechanical part of the quarter turn enclosure is housed in an aluminum lid cast separately from the base of the main enclosure. It is sealed to the base with three screws and an environmental seal. The drive is taken from the motor by the third stage pinion shaft, supported by roller bearings, and into the gear-train. There is a long flamepath along the length of the third stage pinion shaft between the bearings. The gear-train consists of three connected gears which reduce the output RPM and increase the torque. The output shaft is the final shaft passing the drive through the enclosure into the hazardous area through the lid via bronze bushings. The output shaft is connected to a feedback shaft which penetrates into the electronic enclosure through a bronze bushing creating two flamepaths, one on either side of the bushing. Sensors are connected to the feedback shaft to report the position of the actuator to the logic PCB. The final gear is attached to the output shaft and is a half gear with a flat face in order to limit the maximum turning movement of the actuator.The linear actuator is available in a low temperature variant which uses different seals to allow the equipment to be used in the lower minimum ambient temperature of -40°C.CMR – Rotary Compact Modulating ActuatorSimilar in design to the Quarter-turn, the Rotary variant mechanical side is housed in an aluminum lid cast separately from the base of the main enclosure. It is sealed to the base with three screws and an environmental seal. The drive is taken form the motor by the third stage pinion shaft, supported by roller bearings, and into the gear-train. There is a long flamepath along the length of the third stage pinion shaft between the bearings. The drive is transferred from this shaft onto the fourth stage pinion shaft and finally onto the output shaft which transfers the drive into the hazardous area via a bronze bushing. The output shaft is supported on a single steel roller bearing and also acts as a feedback shaft by passing into the main enclosure, creating a flamepath and allowing sensors to report the actuator position to the logic PCB.Page 1 of 3CML-a.

Site Master is a precision analysis tool which measures SWR, Return Loss and Distance-T o-Fault (DTF) on both analog and digital transmission lines.Site Master’s DTF and Return Loss (SWR) measurements are accurate and repeatable, even in the presence of RF interference.Thus,small degradations to RF performance can be spotted before more serious damage occurs.For example, loose connectors and moisture intrusion can be detected before corrosion destroys the cable −saving thousands of dollars in material and re-installation costs.Since sixty to eighty percent of a typical cell site’s problems are caused by problematic cables, connectors and antennas, Site Master pays for itself quickly.Site Master isolates transmission faults using Frequency Domain Reflectometry (FDR).FDR technology is different from traditional TDR (Time Domain Reflectometry)techniques.The FDR technique uses RF frequencies instead of TDR type DC pulses.Thus, FDR can locate RF faults, not just DC open or short circuit conditions.FDR also accounts for cable attenuation versus distance,the display accurately indicates the return loss of the antennas −allowing technicians to perform fault isolation from ground level.Internal memory provides an efficient means of storing measurement data for future analysis.Site Master includes advanced software tools for archiving data.Limit lines provide a quick visual and audible pass/fail indication.Site Master’s rugged construction and wide temperature range provide trouble-free operation in the field.Powerful Software Tools Return Loss or SWR data is down loaded to PC via RS-232.Site Master Software Tools calculate Distance-T o-Fault (Return Loss versus Distance) and Smith Chart.During the Site Commissioning process, the antenna system’s Return Loss (SWR) and Distance-To-Fault “Signature”characteristics are down-loaded to a PC database.Maintenance technicians recall the “Signature”characteristics for comparison tosubsequent monthly/quarterly maintenance verification.The Windows based “drag-and-drop”capabilityspeeds fault identification.Site Master™n Distance-To-Fault Measurementsn Accurately Tests RF Transmission Lines and Antennas n Precision SWR and Return Lossn Immunity to Live Site RF Interference n Synthesizer Accurate to 75 ppmnInternal Memory Saves Up to 40 Traces and 9 Setups Software Toolsn Smith Chart and Distance-To-FaultnCompare Measurements to Historical DataUse the Smith Chart for impedance matching of antennas and trans-mission line quality checks.Historical performance changes can be eval-uated by overlaying stored data traces on a personal computer.0−40−60−200 - 5 metersDistance To Fault−801981Immunity to RF Interference Site Master’s design is highly resistant to interference from incoming and ambient signals.RF suppression capabilities are realized with fre-quency-selective, narrowband receiver technology and a proprietary phase tracking synthesizer technique.RF modulation is transparent to the Site Master making it useful in any cellular modulation environment.Distance-To-Fault displays represent Return Loss or VSWR information.Measurement AccuracyMeasurement accuracy depends on the quality of the coaxial calibration components.The charts below show the Measured Value (dB) vs.Uncertainty for standard and precision calibration components.Ordering InformationModel S331 (25-3300 MHz), Built-in DTF Model S111 (300-1200 MHz), Built-in DTF Model S330 (700-3300 MHz)Model S110 (600-1200 MHz)Standard Accessories Included:• Operating Manual • Soft Carrying Case• Standard Calibration Components • AC-DC Adapter• Automotive Cigarette Lighter/12 Volt DC Adapter• One Y ear Warranty (includes battery, Firmware and Software)• 3.5 inch Floppy Disk containing Fault Location (DTF), Smith Chart and Software Management T ools • Serial Interface CableOptional Accessories/Spares:Precision N T ype Short-Open:PN 22N50Precision N T ype Load, 42 dB:PN SM/PL Test Port Cable, Armored, 1.5 meter:PN TP/EC 1.5Test Port Cable, Armored, 3.0 meter:PN TP/EC 3.0Test Port Cable, Armored, 5.0 meter:PN TP/EC 5.0Test Port Cable, Non-Armored, 1.5 meters PN TP/ECN 1.5Test Port Cable, Non-Armored, 3.0 meters PN TP/ECN 3.0Test Port Cable, Non-Armored, 5.0 meters PN TP/ECN 5.0Spare Standard N T ype Short:PN SM/STS Spare Standard N T ype Load, 35 dB:PN SM/STL Spare Soft Carrying Case:PN D41955Spare AC-DC Adapter:PN 40-74Spare Automotive 12 Volt Adapter:PN 806-62Spare Serial Interface Cable:PN 800-441Transit Case for Site Master:PN 760-194N male to 7/16 female Adapter PN 510-90N female to 7/16 female Adapter PN 510-91N male to 7/16 male Adapter PN 510-92N female to 7/16 male Adapter PN 510-9376432150 -
