PK-88 OPERATING MANUAL
4.8.1
Monitoring Other Stations
Use the MONITOR parameter to set the monitoring method; what stations will or
will not be monitored and the type and amount of information shown by the
monitor.
MONITOR takes a numerical value between zero (0) and six (6). Each higher
number adds more detail to the monitoring. As the value of the MONITOR setting
is increased, additional functions are included in the monitoring sequences.
The meanings of the MONITOR numbers are:
0
Monitoring is disabled.
1
Only unnumbered, 'unconnected' frames are displayed. Use 1 for
'unprotocolled,' communication with multiple stations. Other connected
stations using the frequency are not displayed. This setting will also
display beacons.
2
Numbered (1) frames are also displayed. I-frames are numbered in order of
generation and appear in a connected transmission. Use this to monitor
connected conversations in progress.
3
Connect request (C) frames and disconnect (D) frames are also displayed
with the headers.
4
This is the PK-88's default value. Unnumbered acknowledgment (UA) of
connect and disconnect frames are also displayed with either the
characters UA or DM and a header.
5
Receive Ready (RR), Receive Not Ready (RN), Reject (RJ), Frame Reject
(FR) and I-Frames (I) are also displayed.
6
Poll/Final bit and sequence numbers are also displayed.
Before this next step, verify that your loopback test cable is still connected
to the PK-88's J2 RADIO connector.
•
Type: <CTRL-C> D <RETURN> to make sure you are DISCONNECTED.
•
Type: MONITOR 4. The PK-88 responds with: MONITOR was 4.
•
Type: CONVERSE, then type: 'This is a test packet.'
Your monitor now shows:
MYCALL>CQ:This is a test packet.
Because the UNPROTO parameter is defaulted to the address CQ, your packets are
sent to CQ - you are not connected to any other station. Your packet was
'heard' and decoded by the PK-88 and displayed with the packet header
containing the sending station's call sign and the destination.
