11.6.5 LCD Status and Mode Indicator
The front panel LCD display provides mode and status information at a
glance. This is especially useful in PACTOR operation. The following
describes typical status indications you will see.
Type "PTCONN (CALLSIGN of distant station)." The status changes to:
LCD: PACTOR ARQ PHASE, TX and CONNECT
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-900 is synchronized with the distant station, the
status changes to:
LCD: PACTOR ARQ TFC, TX and CONNECTED
Verify the link by typing <Enter> a few times and 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
TRAFFIC whenever your typing pauses and resumes.
When errors occur on the link and the distant station sends REQUEST
(request for repeat), the status will show:
LCD: PACTOR ARQ ERROR and/or REQUEST, TX and CONNECTED
ERROR: Your PK-900 has detected errors in the signals
received from the distant station.
REQUEST: Your PK-900 has received a "request for repeat"
code from the distant station.
If the link fails and you lose synchronization with the distant
station the PK-900 goes to standby and the status shows:
LCD: PACTOR, STANDBY
For the unproto mode:
After typing" PTSEND", to start an unproto transmission, your PK-900
displays the system status:
LCD: PACTOR FEC IDLE, TX
As you send your traffic the status will change back and forth from
IDLE to TRAFFIC. Whenever you stop typing, the IDLE status is
displayed.
