Changing the Baud Rate in the H-ADCPs

The H-ADCP 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 H-ADCP. This procedure assumes that you will be using the
program BBTalk that is supplied by Teledyne RD Instruments.

WorkHorse H-ADCP Operation Manual
Connect the H-ADCP to the computer and apply pow-
er.
Start the BBTalk program and establish communica-
tions with the H-ADCP. Wakeup the H-ADCP by sending
a break signal with the End key.
At the ">" prompt in the communication window, type
CR1 then press the Enter key. This will set the H-ADCP
to the factory default settings.
Send the CB-command that selects the baud rate you
wish. The table on the left shows the CB-command
settings for different baud rates with no parity and 1
stop bit.
For example, to change the baud rate to 115200, at
the ">" prompt in the communication window, type
cb811 then press the Enter key.
The CB? command will identify the communica-
tion setting.
BBTalk will send the command CK to save the new
baud rate setting.
Exit BBTalk.
The H-ADCP 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.
Exit BBTalk so the communication port is availa-
ble for use with other programs.
