5.2 Initial Startup & Checkout
In-service operation of the transceiver is completely automatic. Once
the unit has been properly installed and configured as described above,
operator actions are limited to observing the front panel LED indicators
for proper operation.
If all parameters are correctly set, operation of the radio can be started
by following these steps:
1. Apply DC power. Unit must be powered on
2. Observe the LED status panel for proper indications (Table 10).
3. If not done earlier, refine the antenna heading of the station to maxi-
mize the received signal strength (RSSI) from the Master Unit. The
Maintenance & Status>>Performance
Turn the antenna heading slowly so that the RSSI display can be
updated.
NOTE: The RSSI facility limits the maximum displayed signal
strength to –60 dBm. Signal levels that are higher than -60
dBm will appear as > -60 dBm.
Table 10. LED Status Indicators
LED Name Description
PWR • Continuous—Power applied, no problems detected.
• Rapid flash (5 times-per-second)—Alarm indication, or
RX/TX frequencies not set.
LAN • Flashing—Data is being transmitted and received.
• Off—Ethernet signals not detected
DATA1 / DATA2 These LEDs show data activity on the DB-9 serial payload
ports (COM1/COM2).
LINK When lit, indicates that a communication link exists with the
Master Unit.
