What components make up a MCTAS485 or a MCT485 terminator?

MCT485 = Multi Communcations Terminator for RS485 connections (has spade lug connectors)

  • MCTAS485 = Multi Communcations Terminator for PowerLink AS panels for RS485 connections (has tinned wire terminals)
  • Both terminators contain a 100 ohm, .25 watt resistor in series with a .047uf capacitor. There are 2 sets required for a each MCT connection. One set should be connected across the RX+ and RX- and one across the TX+ and TX-.
  • See attached internal wiring diagram of the MCTAS485. The wiring diagram is the same for the MCT485.
