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.
8 RS-232 Interface
The RS-232 interface is for interconnecting the RCM-26 module and multi-media control systems or facility
management systems. All parameters can be controlled and queried via RS-232 interface. Communication
is realized through the use of ASCII-protocol. Implementation of this protocol is rather simple.
