SEM products with a serial interface may be connected to a system in either single or party (multidrop) configuration.

The key differences to note between Lexium MDrive and MDrive/MForce products is that with Lexium products the interface is galvanically isolated. MDrive/MForce products:

  • are not isolated
  • have a 100Ω resistor in series with communications ground

This variance necessitates a change when wiring multidrop systems to prevent recirculating currents: See this Application Note: Recirculating currents in RS-422 multi-drop systems

Covers installation of the  USB to serial communication converters offered by SEM, as well as tips for using third-party communications converters.
