LED Status and Mode Indicators
All the LEDs on the front of the PK-232 are there to help give you the units status at a
glance. This is especially true in AMTOR operation.
The following describe typical LED status indications you will see.
Type
ARQ (SELCALL of distant station)
. The LEDs change to:
STATUS:
SEND lit, PHASE lit
MODE:
ARQ lit
These LEDs show that your transmitter is in the SEND condition, in the "phasing" part of
an ARQ selective call. Your transmitter will key on and off sending the distant station's
SELCALL. As soon as your PK-232 is synchronized with the distant station, the LEDs
change to:
STATUS:
SEND lit, TFC and IDLE lit alternately by data flow
MODE:
ARQ lit
Verify the link by typing a few <Enter>s; watch the display. Your traffic will now begin to
flow as you type characters. If EAS is set ON, your typed characters are displayed as they
are acknowledged by the distant station. The IDLE and TFC LEDs change back and forth
whenever your typing pauses.
If errors occur on the link and the distant station sends RQ (Request for Repeat), the
LEDs show:
STATUS:
SEND lit, ERROR and/or RQ lit
MODE:
ARQ lit
ERROR lit:
Your PK-232 has detected errors in the signals received from the dis-
tant station
RQ lit:
Your PK-232 has received a "request for repeat" code from the distant
station
If the link fails and you lose synchronization with the distant station your PK-232 auto-
matically tries to re-establish synchronization with the distant station. The LEDs change to
show:
STATUS:
SEND lit, PHASE lit, ERROR and RQ alternately lit
MODE:
ARQ lit
After typing FEC, your PK-232 displays system status on its LEDs:
STATUS:
SEND lit, IDLE lit, TFC lit only briefly
MODE:
FEC lit
