PK-232 – MBX OPERATING MANUAL COMMAND SUMMARY
4/91 A-18 143
AU
delay "n" Default: 2 (20 msec.)
Mode: Baudot, ASCII, FEC, FAX and Packet Host: AQ
Parameters: "n" - 0 - 120 specifies in units of 10 msec. intervals, the delay between PTT going
active and the start of the transmit AFSK audio tones.
In some applications it may be desirable to create a delay from the time that the radio PTT line is
keyed and the time that audio is produced from the PK-232.
Most notably, on HF when an amplifier is used, arcing of the amplifier relay contacts may occur if
drive to the amplifier is applied before the contacts have closed. If arcing occurs, increase AUDE-
LAY slowly until the arcing stops. In VHF or UHF FM operation, some synthesized transceivers may
produce undesirable spurious emissions, if audio and PTT are applied at the same time. These
emissions may be reduced by setting AUDELAY to roughly 1/2 of TXDELAY.
Please note that AUDELAY must always be less than TXDELAY. It is advisable that AUDELAY be set
lower than TXDELAY by a setting of 10. For example, you have determined that a TXDELAY of 20
works well for your transceiver. Subtracting 10 from 20 yields 10, which is the recommended set-
ting for AUDELAY. If a setting of AUDELAY of 10 is too short, then set both TXDELAY and AUDELAY
higher.
AUTOB aud ON|OFF Default: OFF
Mode: Command Host: Ab
Parameters: ON - Autobaud Routine always present at Power-ON or RESTART.
OFF - Autobaud Routine active at Power-ON only if battery jumper is removed.
When AUTOBAUD is OFF (default), the unit performs the autobaud function only when powering
ON or after a RESET. When AUTOBAUD is ON, the PK-232 performs the autobaud routine EVERY
time it is powered ON, and EVERY time the RESTART command is entered. The stored parameters
(e.g. MYCALL) are saved if the battery jumper is connected. The unit displays the autobaud mes-
sage at the same rate as the last setting of TBAUD. AUTOBAUD ON is helpful when moving the
unit from one computer to another, where the terminal data rates are different.
In the autobaud routine, only one asterisk (*) is needed to set the terminal speed TBAUD. The au-
tobaud routine detects 110, 300, 600, 1200, 2400, 4800 and 9600 baud, at either 7 bits even par-
ity, or 8 bits no parity.
AW len "n" Default: 7
Mode: All Host: AW
Parameters: "n" - 7 or 8 specifies the number of data bits per word.
The parameter value defines the digital word length used by the serial input/output (I/O) terminal
port and your computer or terminal program. AWLEN will probably be set properly by the PK-232
Autobaud routine. Still you may want to change the ASCII word-length at some time to accommo-
date a terminal program you wish to use.
For plain text conversations with the PK-232, an AWLEN of 7 or 8 may be used. For binary file
transfers and HOST Mode operation, an AWLEN of 8 MUST be used. The RESTART command must
be issued before a change in word length takes effect. Do NOT change AWLEN unless the terminal
can be changed to the same setting.
