Introduction

Using the Motorola Radio Service Software (RSS), installed on a suitablePC computer, and these instructions, the Motorola MTR2000 station can beconfigured for use with the Raider and Marauder Trunking controllers. Thissupplement supports MTR RSS revisions up to R03.02.01. Answers to specificquestions pertaining to the use of the RSS can be found in the Radio ServiceSoftware Startup Manual provided with your software.

Setup Instructions

1. Start the Radio Service Software (RSS) and connect the MTR2000 stationto your computer. Read the contents of the stations Codeplug.

2. From the Station Configuration window, click on the Edit Config button andthe Station Configuration window should appear. (Figure 1 below)

3. All marked options in the Configuration window are items that must beselected just as they are shown. Other options may or may not be selecteddepending on the exact options installed in the MTR2000 or your particular

installation.

4. Now click on OK to return to the Station Configuration window. The pulldown menus will become active now.

5. Click on Personality, and click on RF Options. Compare the window thatopens up with Figure 2 and make any necessary changes in the RSS. Whendone, click OK to close the window.

6. Click on Personality, and click on Wireline. Compare the window thatappears with that in Figure 3 and make any necessary changes in the RSS.

Everything must appear exactly as shown. When done, click OK to close thewindow.

7. Click on Personality, and click on TRC Commands. All eight CommandList Options should show None.When done, click OK to close the window.

8. Next, Click on Personality, and click on Channel Information. A window,as in Figure 4, will appear. Make sure that the TX Idle frequency is the sameas the Transmit frequency. Re-enter the frequency if necessary.

9. Now, in the upper left hand corner of the Channel Information windowunder Option, click on Audio. A window should appear as in Figure 5.Every option in this window must be checked or unchecked so that itmatches Figure 5 exactly. Alarm Tone and Call Sign are the only optionsthat may differ.

10. Continue on to the next line, PTT, in the Option window. When you clickon this one, the window that appears should look like the one in figure 6.Make sure that you correctly select the two options indicated by the arrows.Failure to do so can cause loss of transmit data.

11. The next item to be selected from the Option window is Encoder andDecoder. These two should both have None in the Type window asindicated by the arrows in Figures 7 and 8. Click OK to close the ChannelInformation window.

12. Write the current profile to the station and save it to disk. As soon as youget the Station Successfully Written in the message window, proceed tothe alignment portion of these instructions.

Alignment Procedure

1. Make sure that all alignment procedures from the Service pull down menuhave been performed except for the TX Wireline , Discriminator and the

Aux TX Input. These will need to be performed separately.

2. Connect a telephone transmission test set, in the terminated mode, to theLine 1 input of J6 on the rear of the station. Set it to transmit a 1004Hz toneat20.0dBm.

3. Click on Service in the pull down menu and select Station Alignment. Nowselect the TX Wireline button from Audio Input/Output. See figure 9.

4. After you click TX Wireline you will get a window that looks like figure 10.With the Transmission Test Set in the generate mode, type20 in the box forthe Level of test tone and click on Save. The station will immediately autocalibrate, temporarily store the value and then return you to the Station

Alignment window.

5. Connect the Raider or Marauder controller to the MTR2000 station at this

time. With the top cover removed from the controller, install jumpers W22,W26 (Remove W26 in the Marauder) and W30 if they are not alreadyinstalled.

6. Remove the Telephone Transmission Test set and connect an Oscilloscopeto pin 1 of U1 in the controller. Connect a Service Monitor to the RX port ofthe MTR Station set in the generate mode at an RF level of approximately

80dBm.

7. Generate a 1KHz tone deviating at 2KHz (1KHz for narrowband operation)and click on the Discriminator button in Audio Input/Output. See figure 9.

8. Adjust the slider, (see figure 11), to obtain a 2Vp-p signal on pin 1 of U1measured with an Oscilloscope. Click Save to return to the Station

Alignment window of figure 9.

9. Set the Service Monitor to Receive on the Stations transmit frequency.Move the Controllers TX Test switch, SW4-2, to the down position and adjustthe TX Data potentiometer, R57, to obtain a 2Vp-p signal of low speed data,

measured with an Oscilloscope, at pin 8 of U2.

10. Click on the Aux TX Input button under Transmitter, (see figure 9), andadjust the slider, as in figure 12, to obtain 1KHz deviation (800Hz for narrowband operation) of low speed data as measured by the service monitor.Click Save to temporarily save the calibration data.

11. Now, click Save from the Station Alignment window to permanently writeall the calibration data, from the previous steps, to the codeplug. If a StationSuccessfully Aligned message appears in the Message Window, you mayproceed to the setup instructions in the controller manual to complete systemintegration.

Please note the 6 items marked on Figure1. These options must be selectedexactly as shown for the external controller to function properly. The otheroptions may be left just as they are.

Figure 2

The Raider and Marauder series controllers have a built in Time Out Timer (TOT)

and CW Station ID. It is recommended that these features be disabled in theMTR2000 station and programmed into the controller.

Figure 5

Every option on this screen must be selected exactly as shown except for CallSign and Alarm Tone. If any item is forgotten, the external controller will notoperate properly. Items of extra importance are indicated by the arrows. TheRaider and Marauder have a built in CW Station Identifier that is fullyprogrammable over a modem. It is recommended that this Identifier is used

instead of the one built into the MTR-2000.
