Stand Serial Control

Standard Serial Mode

In this mode S1 accepts TTL level byte commands. Standard serial mode is one way serial data.

RoboClaw can receive only. A standard 8N1 format is used. Which is 8 bits, no parity bits and

1 stop bit. If you are using a microcontroller you can interface directly to RoboClaw. If you are

using a PC a level shifting circuit (eg: Max232) is required. The baud rate can be changed using

the SET button once a serial mode has been selected.

Standard Serial communications has no error correction. It is recommended to use

Packet Serial mode instead for more reliable communications.

Standard Serial Command Syntax

The RoboClaw standard serial is setup to control both motors with one byte sized command

character. Since a byte can be any value from 0 to 255(or -128 to 127) the control of each motor

is split. 1 to 127 controls channel 1 and 128 to 255(or -1 to -127) controls channel 2. Command

value 0 will stop both channels. Any other values will control speed and direction of the specic

channel.
