• PC configurator software (model: JXCON)
Downloadable at M-System’s web site.
A dedicated cable is required to connect the module to the
PC. Please refer to the internet software download site or
the users manual for the PC configurator for applicable
cable types.
• Optional power switch
Typical Applications
• Various 2-wire transmitters
