necessary to activate it by re-initializing the MC16 controller with connected expander (

command in VISO software).
Note: Any modification of license file will corrupt the file. The expander cannot operate without valid license.
Power supply and backup battery
MCX16 module is designed for power supply from 230VAC/18VAC/40VA transformer and then it offers
12VDC power outputs (AUX, TML) for external devices. Optionally the expander can be supplied from
12VDC or 24VDC but in case of 12VDC the backup battery cannot be directly connected to the expander
thus the emergency power supply must be provided by external PSU.
Note: MCX16 module cannot be started using only power supply from backup battery.

IN1..IN8 inputs
The expander offers 8 inputs which can be configured as NO or NC. The configuration of input electrical
parameters is done within low level configuration by means of RogerVDM software. Inputs are assigned with
functions using VISO management software.
OUT1-OUT6 outputs
The expander offers six open collector type transistor outputs OUT1-OUT6. Output polarity can be
configured as normal or reversed. Output with normal polarity represents high impedance in normal state
and is shorted to ground when triggered. Output with reversed polarity operates with inverted logic. It is
shorted to ground in normal state and represents high impedance when triggered. The configuration of
