AMC MUX and AMC MUX-EXT Abstract | en 13 Abstract The AMC MUX rail mountable module converts RS-232 signals into bi-directional RS-485-2/4-wire or RS-422. The AMC MUX is designed for industrial applications in a control cabinet or switchbox. If expansion to eight RS-485 interfaces is required, use the AMC MUX-EXT expansion module.

Each additional AMC MUX-EXT plugged into allows for an additional 1200m (4000 ft) bus extension. – Up to seven AMC MUX-EXT can be plugged to an AMC MUX. – RS-485 branches from bus to AMC2 4W allowed up to 100m (300 ft).
Star wiring up to 1200m (4000ft) cable length is acceptable. Applications You can install the AMC MUX module in different places in the system. One option is to convert the COM interface of the PC into RS-485/RS-422 (Figure 4.4).
