Setting The Baud Rate In The Channel Master. The Channel Master can be
set to communicate at baud rates from 300 to 115200. The factory default
baud rate is always 9600 baud. The baud rate is controlled via the CB-
command. The following procedure explains how to set the baud rate and
save it in the Channel Master. This procedure assumes that you will be us-
ing the program BBTalk that is supplied by RD Instruments.
a. Connect the Channel Master to the computer and apply power (see
“Setup the Channel Master,” page 10).
b. Start the BBTalk program and establish communications with the
Channel Master. Wakeup the Channel Master by sending a break sig-
nal with the End key.
c. Send the command CR1 to place the Channel Master in the factory de-
fault setup.
d. Send the CB-command that selects the baud rate you wish. The fol-
lowing are the typical CB-command settings for different baud rates
with no parity and 1 stop bit:
Table 9: Baud Rate
BAUD RATE CB-command
1200 CB111
2400 CB211
4800 CB311
9600 CB411 (Default)
19200 CB511
38400 CB611
57600 CB711
115200 CB811
e. BBTalk will change the communication settings to match your CB
command settings.
f. Send the command
CK to save the new baud rate setting.
g. Click File, Close to exit the terminal window.
The Channel Master is now set for the new baud rate. The baud rate will
stay at this setting until you change it back with the CB-command.
NOTE. If you send a BREAK before changing the external device’s
communication parameters, the Channel Master returns to the
communication parameters stored in non-volatile memory (user settings).
