- Motor current is readable.
- Only 24v is required to power the module.

Connections
Automatic Speed regulation
By using feedback from the encoders the MD49 is able to dynamically increase power as required. If the required speed is not being achieved, the MD49 will increase power to the motors until it reaches the desired rate or the motors reach there maximum output. Speed regulation can be turned off with the use of the REGULATOR DISABLE command.
Automatic Motor Timeout
The MD49 will automatically stop the motors if there is no serial communications within 2 seconds. This is to prevent your robot running wild if the controller fails. The feature can be turned off with the DISABLE TIMEOUT command.
Controlling the MD49
The MD49 is designed to operate with a TTL level serial bus (5v levels) at either 9600 or 38400 baud depending on the jumper selection and accepts either one or two stop bits. A jumper is supplied to make the default shipped baud rate 38400. Do not connect the MD49 to RS232 directly, if you wish to connect to RS232 it must be with the aid of a voltage level converter such as a ST232 or serial interface such as S13 which is available here: www.robot-electronics.co.uk/acatalog/Serial_Interface.html
