4.5.3 RF DATA
Figure 4-20 RF DATA
The RF Line Monitor window shows the state of
the lines (see Figure 4-19). These lines are monitored
by the A-D converter in the IAC. The normal values
for each line are defined as follows.
Synthesizer Lock Lines:
Exciter Synthesizer
Yes, No
Receive Synthesizer Yes, No
Exciter High Stability Yes, No
Receive High Stability Yes, No
Wideband Audio Output approx. 200
LO Injection approx. 200
RSSI 20-150
Fan 1 Current 100-200, 0
Fan 2 Current 100-200, 0
Transmit Parameters:
Forward Power (Low Power
25-75 Watts
Forward Power (High Power) 75-175 Watts
Reflected Power 0-6 Watts
Final Out 1-2 (ratio) approx. equal
Final Out 3-4 (ratio) approx. equal

Values with no label are the actual A-D reading.
To calculate the voltage on the line, divide the value
by 51. Example: Value
÷
51 = Volts. Any variation
from the above values may indicate a problem in that
area. Values in this window are relative measurements
only.
4.5.4 INPUT MONITOR
This window monitors the two Analog Input
lines. It is only used with the 4-Alarm Type IAC, and
only if Input 3, Input 4 or both are programmed for
"Analog". In addition to the actual or measured value,
the Low/High limit data are also displayed. These
limits are programmed in the "Edit -> Repeater Infor-
mation -> Input Alarms" screen (see Figure 4-13). If
one of these inputs is not programmed "Analog", the
data for that input is blanked.

4.5.5 REVISIONS
This menu selection has an equivalent icon in
the toolbar. This menu selection or icon dis-
plays the current firmware revision informa-
tion for the MPC, MAC and HSDB. The format is R.V
(revision.version) for all modules. The MPC informa-
tion also includes the release date of the software and
the serial number of the repeater. The HSDB version in
Figure 4-22 is for J4, pins 5-6 connected in the MPC for
LTR-Net (J4, pins 3-4 connected in the MPC are for
standard LTR).
