PRELIMINARY
4.2.9 Bitrate Command
Purpose: To set the bitrate of the serial communications link. The bitrate is changed immediately after
the successful receipt of this command. (The default bitrate is 9600.)
Type: This is a write only command.
Write Command: Cmd-ID R/W-Flag Data Length Data
0x44 0 4 4 Bytes
Response: None
Data Format: Byte 1 An ID that specifies the bitrate (see table below).
Byte 2 undefined - always write 0x00
Byte 3 undefined - always write 0x00
Byte 4 undefined - always write 0x00
ID Bitrate
0x12 4800

When changing the bitrate for serial communication, use the following procedure:
1. Issue the write command with the new bitrate.
2. Wait one second.
3. Change the bitrate on the serial port that the camera is using:
a) If you are using a Camera Link frame grabber, change the bit rate on the
frame grabber’s RS-644 serial port.
b) If you are using the camera with a k-BIC, change the bit rate on your PC’s
RS-232 serial port (
A501k/kc only).
4. Restart the PC and the camera.
5. Resume communication.
Note: The RS-644 serial port on some Camera Link frame grabbers will only support
a bitrate of 9600. If you are using a Camera Link frame grabber, check the grabber’s
documentation before attempting to change the bitrate.
