Rane SR 2 - Manual (Page 4)

Manual-4
Rear Panel Description
1 6-wire Euroblock connector. Connects the SR 2 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 2. This, for example, allows a
keyed switch to be installed next to the SR 2 that allows the device to be
“locked” so only keyholders can change system volume.
2 Device Address switch to assign the device its RW 485 address. Addresses
0 through 7 are valid.
