Video output signal conforms to CCIR PAL or NTSC 1V Composite format. Telemetry signals all
conform to the RS-485 / RS-422 standard. The unit continuously monitors incoming telemetry
whether in full or half duplex mode.
In full duplex mode, the Tx pins are tri-state except during transmission times. This may cause
problems when interfacing to some fiber optic converter units. Check out the Commissioning
notes for ways of overcoming these problems. In 2 wire Half Duplex mode (RS-485), the Rx
pins are used to transmit data to the MIC440.
The washer connections can be used to operate a relay in the power supply unit, which in turn
can activate a pump.
