Changing the Baud Rate in the ADCPs
The RiverPro/RioPro can be set to communicate at baud rates from 1200 to 115200. The factory default
baud rate is always 115200 baud. The baud rate is controlled via the CB-command. The following proce-
dure explains how to set the baud rate and save it in the RiverPro/RioPro. This procedure assumes using
the program BBTalk that is supplied by Teledyne RD Instruments.

[Parameters set to FACTORY defaults]
Connect the RiverPro/RioPro to the computer and ap-
ply power.
Start the BBTalk program and establish communica-
tions with the RiverPro/RioPro.
Wake up the RiverPro/RioPro 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
RiverPro/RioPro to the factory default settings.
BAUD RATE CB-command
1200 CB111
2400 CB211
4800 CB311
9600 CB411
19200 CB511
38400 CB611
57600 CB711
115200 CB811 (Default)
Send the CB-command that selects the baud rate you
wish. The table on the left shows the CB-command set-
tings 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.
CB = 411 ----------------- Serial Port Control (Baud
[4=9600]; Par; Stop)
>cb811
>CK
[Parameters saved as USER defaults]
>cb?
CB = 811 ----------------- Serial Port Control (Baud
[8=115200]; Par; Stop)
>
BBTalk will send the command CK to save the new
baud rate setting.
Exit BBTalk.
The RiverPro/RioPro is now set for the new baud rate.
The baud rate will stay at this setting until changed
again with the CB command.
Exit BBTalk so the communication port is availa-
ble for use with other programs.
