[BAUD]

This command displays the current BAUD rate 
setting.

Command Format:  [BAUD]

Example:

Display the BAUD rate setting by sending the 
command [BAUD] and receiving feedback 
similar to the following:

BAUD=9600

23.  

[BAUD=]

This command sets the baud rate via the 
RS-232 bus. The baud rate may also be set 
from the front panel keys.

Command Format:  [BAUD=n]

n

= 1200, 2400, 4800, or 9600

Example 1: RS-232 BUS

Set the baud

rate to 9600 by sending

[BAUD=9600]. The system will return feedback
similar to the following:

?w3%baud=9600$#7f&changed?

Example 2: FRONT PANEL

Each rate is represented by one of the following 
front panel keys:

 Key 1 = 1200

Key 2 = 2400

 Key 3 = 4800

Key 4 = 9600

In order to change the baud rate, perform the 
following steps:

1)

Press & Hold both  keys 5 and 6 

simultaneously for 2.5 seconds.

2)

LEDs 1, 2, 3, and 4 will turn on and one of 

the four will be flashing. The flashing LED 
represents the current baud rate setting.

3)

Press & Hold for 2.5 seconds the key 

representing the desired baud rate.

4)

After 2.5 seconds, all 4 LEDs will be 

extinguished.

5)

The new baud rate is set.

SPECIAL COMMANDS

These commands allow special character strings to 
be sent to external devices. The strings may be 
used to issue commands to custom equipment 
connected to the MultiTasker. Also included in this 
section are commands to test the internal memory 
and display all available RS-232 commands.

24.  

[TXR]

This command is used to send command strings 
to the RS-232 bus through the MultiTasker.

Command Format:  [TXRxyz]

xyz = text string ("abc","123",…)

Example:

Send the text string "HELLO" to the RS-232 bus. 
The string will be ignored by the MultiTasker, but 
not the unit receiving the command. To do this, 
send the command [TXRHELLO] and the 
following will be sent to the remaining devices 
connected to the RS-232 bus:

HELLO

25.  

[TXM]

This command is used to send command strings 
to the RS-232 bus through the MultiTasker, but 
it adds opening and closing brackets to the 
command string.

Command Format:  [TXRxyz]

xyz = text string ("abc","123",…)
