Set Up an OTA Mobile Unit
1. Log in to the radio.
2. Go to the System Configuration Menu.
3. Set the timing source to OTA and allow the radio to reboot (factory-new units default to OTA, so
this step may be skipped).
4. Logging in again after the reboot, verify that the radio's Device Status is
on the Starting Information Screen. If not, type 'A' to get a list of the current alarms and correct
the alarm condition.
5. Go to the STFP Configuration Menu (Under the System Configuration Menu)
a. Set the STFP radio ID from the default 0. (It's recommended.)
b. Set the IP Port on which the mobile will receive STFP messages from the
Communication Manager.
c. Set the IP Address of the Communication Manager to which timing markers and
messages received from bases should be sent.
d. Set the IP Port of the Communication Manager to which timing markers and messages
received from bases should be sent.
e. Set the epoch size to match the same value configured on the neighboring radios and
reboot if necessary.
f.
Set the STFP slot delay as necessary. This number, multiplied by 125ms, represents the
slot delay allowed from when a timing marker is sent to the Communication Manager to
when a data message must be received from the Communication Manager. For most
cases the default value of 3 should suffice.
6. Go to the Ping Utility Menu (Under the Maintenance/Tools Menu).
a. Verify the Ethernet Link using the Ping utility.
7. Ensure at least one base is present in the neighborhood of this radio so that it can detect
beacons and synchronize timing.
8. Begin sending STFP data.
9. Verify the TX LED illuminates and the radio begins transmitting over the air.
4.7
Key the Transmitter
1. Log in to the radio on its COM1 console using a serial terminal emulator program.
2. Go to the Maintenance / Tools Menu and then to the Radio Test Menu.
3. Select the frequency for the test transmission.
4. Select the RF Output Power to use.
NOTE
Power levels greater than 2 Watts will timeout after a 20-second period by default. Ensure
ventilation with supplemental forced airflow if longer durations are desired.
5. Select the type of test to
6. Enable test mode.
7. When finished, disable test mode or escape the test menu.
NOTE
When in the Radio Test Menu, all STFP communications to this radio will be temporarily ignored.
STFP communications will resume upon exiting the menu.
