Fochi Posted May 11, 2014 Report Posted May 11, 2014 I need to build a HMI-CAB-C49 cable to establish communication with an old Total Control Quick Panel Jr (Also sold as Proface or GE). I already have the connectors and also the RS232 to TTL converter. I need some additional information on the interconnections, I mean the inner schematics of a good working cable (because The Proface manual is very incomplete). Thanks in advance for the help Quote
