Page 127 MRC-565 Packet Data Radio Operations & Maintenance
7 Maintenance
Maintenance of the MRC-565 has been reduced dramatically because of the use of a Software
Define Radio (SDR). Proper operation is guaranteed through the verification and or adjustment
of a few software and hardware parameters. These parameters are described in the following
sections.
7.1 Script Files
It is critical that the proper script files are loaded before operation begins. These script files
configure the MRC 565 for operation in its specific location. Script files are loaded using
XTERM and can be enter from either the front panel COM port or the Ethernet connector. This
can be done either locally or at a remote connection that has an Ethernet connection to the
Master. Refer to the XTERM manual for details on loading script files.
Of all the parameters that are entered through the script files, only three are unique to each
station. These are:
ID
SERIAL NUMBER
SITE NAME
It’s best to setup script files for each Master with these three parameters and then use and
INCLUDE STATEMENT to add all the common parameters as a file name.
If all are blinking, the internal Power Supply must be working properly, however it’s a good idea
to measure this voltage as noted in the next step.
7.2 Measuring Voltage Levels
There are several voltage regulators on the CMU board. All have test points for measuring
values. A list of test points and there location is shown below.
In addition the following command can be used to verify several of the voltages:
