6-wire Euroblock connector.

Connects the SR 4 to a controller. A con-

nects to RS-485 data +, B connects to RS-485 data –. +V is the positive

side of the power supply rail. –V is the negative/ground side of the power

supply rail. Ground is the connection point for the shield when shielded

cable is used. When the Encoder Lock pin is grounded and Auto Lock is

enabled, encoder input is ignored by the SR 4. This, for example, allows a

keyed switch to be installed next to the SR 4 that allows the device to be

“locked” so only keyholders can change system volume.
