RS-485 circuitry
The communication circuitry has a built-in snubber circuit which eliminates the need of
end resistor. The transceiver circuit is s hort circuit safe and is over voltage protected.
Network cables
Minimum requirements for communication cables: Characteristic impedance 1 00-250
Ohm, 2x twisted pair and outer screen. Cable terminated in a RJ -
45 plug. Signal ‘A’ –
Pin 3, signal ‘B’ – Pin 6, signal ‘Ref’ – Pin 4 and 5.
LEDs
There are four LEDs on each output module: Power indicate s that logic power supply
(24VDC) is present to the module, Rx indicates messages received to the module, T x
