PK-232 MBX – OPERATING MANUAL PACTOR OPERATION
2/93 11-6 118
PTCONN !N7ML <Enter>
If your station doesn't link within a period of time determined by the ARQTMO command
(default 60 seconds), your station will automatically stop transmitting.
11.6.5 LED Status and Mode Indicators
The front panel LED display provides mode and status information at a glance. This is es-
pecially 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 re-
quest. 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 dis-
tant 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. When-
ever you stop typing, the IDLE status is displayed.
