7 CONTROL PORT
The CONTROL PORT of the RCM-26 provides two control inputs, two control
outputs and reference connections for +5V and ground. The control inputs are
configurable via IRIS-Net™. They can be used for example for switching
between power on / standby modes, switching between presets or to control
parameters. The two control contacts IN1 and IN2 are internally connected via
pull-up resistors and carry +5V (open). The control inputs can be activated using
external switches, pushbuttons or relays to connect them to ground potential (pin 3). The two control
outputs OUT1 and OUT2 are open collector outputs, which are highly resistive in the non-active state (off).
In active state (on) the outputs are connected to ground. The control outputs are configurable via IRIS-
Net™ and are used to signal internal states. LEDs, indicators or relays can be driven directly. The +5V
reference connector provides voltage supply for connected components.
