Video output signal conforms to CCIR PAL 1V Composite format. (NTSC format is
available on request).
Telemetry signals all conform to the RS485 / RS422 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 Fibre Optical converter units.
Check out the Commissioning notes for ways of overcoming these problems.
In 2 wire Half Duplex mode (RS485), the Rx Pins are used to transmit data to the
MIC440 unit.
The washer connections can be used to operate a relay in the power supply unit,
which in turn can activate a pump.
