I'm having trouble receiving data from the DMU11

The DMU11 Output Message is output on a RS422 Serial interface at 460,800 baud using a non-return to zero protocol. The DMU11 RS422 driver does not include a 120-ohm termination resistor which is normally associated with the RS422 interface. Therefore, if the user is not going to use the receive feature of the DMU11 (RX Lo and Rx Hi), then a 120 ohm termination resistor needs to be inserted between Pins 3 and 4 of the connector. Pins 3 and 4 should not be left unterminated since noise received on Pins 3 or 4 could cause the DMU11 to stop transmitting data on it transmit lines. Ideally, the termination resistor should be placed as close to the connector as possible.
