The switches T47, T48, T49, T56, T57, T58, T67 and T68 on the EBox controller
RY1917 or RY1601 enable defineing the mode of operation for the GPI inputs.
Position ”1” (to the left) is intended for the following application:
A simple connection between the two connectors activates the corresponding in-
put. This kind of control is suited for the connection to a relay contact or also to an
open collector output. Please note that in this case, one of the two leads is con-
nected with the circuit ground. Therefore, when connecting to an open collector
output, no ground potential isolation is between mixer and controlling device.
