Wiring and Connections
Overview
This chapter provides details, specifications, wiring diagrams, and other important information for all port and
connectors available on the MU-series controllers.
Serial Ports
The MU-series controllers each feature device control serial ports that support either RS-232 or RS-232, RS-422, and RS-
485 communication protocols. Each port supports the following specifications:
•
XON/XOFF (transmit on/transmit off)
•
CTS/RTS (clear to send/ready to send)
•
300-115,200 baud rate
RS-232 Ports
The RS-232 ports (ports 2-4 and 5-8 on the MU-3300; ports 2-4 on the MU-2300; port 2 on the MU-1300) are 5-pin 3.5
mm Phoenix connectors used for connecting A/V sources and displays. These ports support most standard RS-232
communication protocols for data transmission.
The following table lists the pinouts for the RS-232 ports.

RS-232/422/485 Ports
The RS-232/422/485 ports (ports 1 and 5 on the MU-3300; port 1 on the MU-1300/2300) are 10-pin 3.5 mm Phoenix
connectors used for connecting A/V sources and displays
These ports support most standard RS-232, RS-422, and RS-485 communication protocols for data transmission.
