PK-232 OPERATING MANUAL Pactor OPERATION
11.6.5 LED Status and Mode Indicators
The front panel LED display provides mode and status information at a
glance. This is especially useful in Pactor operation. The following
describe typical STATUS indications you will see.
Type "PTCONN (CALLSIGN of distant station)”. The STATUS changes to:
STATUS: SEND and PHASE
MODE: ARQ
This shows that your transmitter is in the SEND condition, in the
“connect" part of an ARQ connect call. Your transmitter will key on
and off, sending the distant station's connect request. As soon as
your PK-232 is synchronized with the distant station, the STATUS
changes to:
STATUS: TFC, SEND and CON
MODE: ARQ
Verify the link by typing <Enter> a few times watch the display. Your
traffic will now begin to flow as you type characters. If EAS (Echo As
Sent) is set ON, your typed characters are displayed as they are sent.
The STATUS will change back and forth from IDLE and TFC whenever your
typing pauses.
If errors occur on the link and the distant station sends REQUEST
(request for Repeat), the STATUS will show:
STATUS: ERROR and/or RQ (ReQuest)
MODE: ARQ
ERROR: Your PK-232 has detected errors in the signals received
from the distant station
REQUEST: 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
the STATUS changes to show:
STATUS: SEND and PHASE
MODE: ARQ
After typing “PTSEND”', to start an unproto transmission, your PK-232
displays the system status:
STATUS: SEND and IDLE
MODE: FEC
As you send your traffic the STATUS will change back and forth from
IDLE to TFC. Whenever you stop typing, the IDLE status is displayed.
