3.2.1.4 RS-232 LED Function Selection
The PF 1 button is used to select the RS-232 dis-
play mode as follows:
• If pressed ONCE (do not hold pressed):
- Clears Alarm indications
- CK LED stops flashing for 2 seconds
- During this time, one or all of the RS-232
numbered LEDs (see Figure 13) will
light. If one LED lights, it denotes the
port to which the subsequent display ap-
plies. If all numbered LEDs light, it de-
notes that the normal 3-port display mode
is active.
The selected display remains active until
manually changed or until RESET is
pressed or until power up.

• If, during the 2 seconds period that CK is not
flashing, PF 1 is pressed a second time, the
LED functions will advance one step from
top to bottom through the available options in
the order shown in Table 4.
• PF 1 may be pressed repeatedly during the 2
second period (extended with each press) to
advance to the desired numbered LED func-
tion option.
Once the desired RS-232 LED function is se-
lected, stop pressing PF1, allow the two-seconds
timer to run down. The BDLC
PD
returns to nor-
mal operation using the newly selected display.
3.2.1.5 LEDs and Indications
LEDs are used to indicate the operation status of
the BDLC
PD
. Although capable of displaying
three colors, only the green and red colors are
used for the BDLC
PD
.
They are grouped by their
function:
• RF Group, displays radio channel status in
green
• RS-232 Group, displays serial port status in
green except the TX LED that also uses red
• ALARM Group, displays fault status in red
3.2.1.5.1 Radio Network Indicators
The Radio Network LEDs are useful when trou-
bleshooting as an indication of network activity.
It can help isolate transmission problems.

CS Carrier Sense - Steady light indicates that an
incoming radio data signal is being detected by
the DSP modem. CS signal is not user-adjustable.
RX Receive Data – Flashing light indicates unit is
internally receiving data from the radio network.
TX Transmitter ON – blinks green indicates
(depending on display mode selected):
• That a data packet or ACK (packet acknowl-
