   for your PC. Follow the on-screen instructions to install the    software.
2) Please refer to the CPS Programming Installation Guide, which you
   received with this software for more detailed information. It is
   essential to follow these instructions in order for communication
   between the PC and radio to work properly.

Connecting the PC to the radio:
===============================
Do not use the Radio Interface Box (RIB), Smart Radio Interface
Box (SRIB) or any of the cables that plug into those boxes.

Use only the following direct PC to radio cables:

 XTS 1500/ XTS 2500/ XTS 5000/ MT 1500/ PR 1500 RS232 cable = RKN4106
 XTS 1500/ XTS 2500/ XTS 5000/ MT 1500/ PR 1500 USB cable = RKN4105
 SSE 5000 RS232 cable = RKN4122
 SSE 5000 USB cable = RKN4121

 ASTRO Spectra Plus / XTL 5000 RS232 cable = HKN6155

 XTL 5000 (with 'O5' Control Head)/
 XTL 2500/ XTL 1500/ PM 1500 RS232 GCAI cable = HKN6183 

 XTL 5000 (with 'O5' Control Head)/
 XTL 2500/ XTL 1500/ PM 1500 USB GCAI cable = HKN6184

 HPD 1000 RS232 Cable = HKN6180

 HPD 1000 USB Cable = HKN6177A (6 ft) or HKN6178A (16.5 ft)

Note: When using the USB cable, be sure to always click "Yes" on the 
Digital Signature window whenever it is displayed by the operating system.
Note that the USB cable can be used only with Windows XP Service Pack 1 or 
higher and Windows 2000 Service Pack 2 or higher operating systems.

Known issues:
=============
1) In the event that PC to radio communications fail even after
   attempting to read the radio multiple times, it might be necessary
   to reset the communications by either turning the radio off/on or
   by disconnecting/reconnecting the cable connected to the radio.

2) PC to radio communications will sometimes fail if you attempt
   to read the radio immediately after closing the previous tuning
   session. Wait for the "hourglass" to disappear before reading
   the radio again.

3) When communicating with the radio over USB on Windows 2000 SP2,     
   certain PC configurations along with specific error conditions
   may cause the PC to reboot or display a blue screen. To limit the
   possibility of occurrence, be sure that your PC meets the minimum
   specifications and be certain that the radio is turned on and the
   cables are properly connected when attempting to read the radio.

4) When entering data in the Transmit Power Characterization screen,
   the values used must be measured values, any other values might
   generate unpredictable results. 

5) The XTL radios and the HPD modem take longer to reset than
   the ASTRO Spectra Plus radios. When tuning these radios, allow enough
   time for the radio to reset before attempting to read/tune the radio 
   again.

6) During HPD BER testing, the Rx Frequency should NOT be changed while 
   the test is running. If the Rx Frequency needs to be changed, please 
   STOP the test, change the frequency, then start the test again.

7) During the HPD BER testing, it is not recomended to transmit while 
   the Rx test is running.
