SMCDU-XX
Our SMCDU-XXX is a compact display driver designed to operate up to four remote MICRO COMM displays from a single control board. It is compatible with any MICRO COMM series display and provides eight floor inputs together with up and down direction inputs.
The board supports AC or DC inputs and includes latched input operation, self-testing, alternate messaging and passing chime output. Built-in cross-wire protection and error detection and correction provide additional resilience, making the SMCDU-XXX a straightforward solution for smaller MICRO COMM display installations.
The signal bridge for modernisation.
A solid-state card that converts what the existing controller already speaks onto the MICRO COMM network, so you upgrade the display without replacing the controller.
