Electro-Voice 250, 1252 operation manual Nexus Meter Port

5.9: RS-485 Connection—Nexus Meter to the Nexus P60N External Display

To connect the Nexus P60N Touch Screen External Display, use the Stand Alone Interface Cable provided with the display. The cable is six (6) feet long with 20 AWG conductors (see detail below). Insert one end of the supplied cable into Port 3 of the Nexus 1250/1252 Meter. Port 3 is factory-set to match the Nexus Display’s baud rate of 9600. To use a port other than Port 3, you must set the port’s baud rate to 9600 using the Communicator EXT software (see the Communicator EXT User Manual). Insert the other end of the cable into the back of the Nexus P60N Display. The connectors fit only one way into the ports.
