Communication
•The MP200 has two serial communication UARTs. It is able to support two
modes of communication simultaneously – either RS232 and IrDA (If DIP switch 1 is on) or RS232 and Bluetooth (If DIP switch 1 is off and DIP switch 5 is on).
•DIP switch 1 is used to control the RS232 port. If the switch is turned on the RS232 port is disabled and if it is turned off the RS232 port is enabled. If RS232 interface is not required, disabling the port will save battery power.
Serial Communication Specification
•The RS232 interface signals for the MP200 printers are terminated on a
•Six connections are provided from the serial interface to the host computer. The serial interface signals and pin outs on the RJ connector, and the connector pin locations are shown below.
•A minimum of two connections are required for operation: RXD – pin 3 and Common
– pin 1.
The communication parameters: baud rate, data bit and parity must be set the same as the host device settings.
