Relay Ports

Relay Pinout
Signal Function
1A Relay 1 Common
2A Relay 2 Common
3A Relay 3 Common
4A Relay 4 Common
5A Relay 5 Common
6A Relay 6 Common
7A Relay 7 Common
8A Relay 8 Common
• Connectors are labeled A and B
• These relays are independently controlled, isolated and normally open
• The relay contacts are rated for a maximum of 1 A @ 0-24 VAC or 0-28 VDC (resistive load)
• If desired, a metal connector strip is provided to distribute 'common' among multiple relays.

I/O Ports

Configurable as voltage sensing or digital output
I/O – Pinout
Signal
GND
1-4
+12vdc
Each pin is individually configurable as a voltage sense input or a digital output
•
• Threshold settings are available to determine the high/low points for the digital input and the required voltage
change to generate an update
• Digital Output can push or pull 100mA

IR/SERIAL Port

Configurable as IR control emulation or 1-way serial
IR/S Port Pinout – MU-2300 & MU-3300 lower port
Signal Function
1- IR 1 GND
1+ IR 1 Signal
2- IR 2 GND
2+ IR 2 Signal
Each pair is configurable as IR or 1-way RS-232
•
• Baud rates for RS-232 are limited. Maximum Baud is 19200 in DATA mode
• RS-232 voltages are 0-5v, not +-12v. This limits the maximum distance based on the cable resistance to <10 ft
IR carrier frequency up to 1.142 MHz
•
All ports can be used simultaneously
•
These ports accept an IR Emitter (CC-NIRC) that mounts onto the device's IR receiver window
•
