PK-232 – MBX OPERATING MANUAL COMMAND SUMMARY
4/91 A-75 200
TDChan "n" Default: 0
Mode: TDM Host: TN
Parameters: "n" - Specifies the TDM channel number.
"n" selects which data channel (default 0) to separate out from the multiplexed TDM signal. n can
be set to 0-3, but only some of these have unique effects:
1-channel: No effect.
2-channel: 0 and 2 show Channel A.
1 and 3 show Channel B.
4-channel: 0 shows Channel A.
1 shows Channel B.
2 shows Channel C.
3 shows Channel D.
TDm Immediate Command
Mode: TDM Host: TV
TDM is an immediate command that places the PK-232 in the TDM receive mode.
TDM stands for Time Division Multiplexing, also known as Moore code and is the implementation of
CCIR Recommendation 342.
Use the PK-232 SIGNAL command first to determine the bit rate and to make sure that the signal
is actually TDM. The SIGNAL command can detect one or two channel TDM transmissions.
The TDM command forces bit phasing; do this when changing frequency to another TDM signal.
This is also useful when the PK-232 synchronizes on the wrong bit in the character stream, which
is likely on a signal which is idling.
TDM stations idle MOST of the time, so you may have to leave the PK-232 monitoring for an hour
or two before any data is received.
TIme "n" Default: $14 <CTRL-T>
Mode: All Host: TM
Parameters: "n" - 0 to $7F (0 to 127 decimal) specifies an ASCII character code.
The TIME command specifies which control character sends the time-of-day in the text you type
into the transmit buffer or into a text file stored on disk.
At transmit time, the PK-232 reads the embedded control code (default <CTRL-T>), reads the
time-of-day from the PK-232's internal clock and then sends the time to the radio in the data trans-
mission code in use at that time. If the DAYTIME has not been set, and a control-T will cause the
PK-232 to send an asterisk (*). When DAYSTAMP is set ON, the date is transmitted with the time.
NOTE: The TIME command cannot be embedded in CTEXT, BTEXT, MTEXT or AAB.
