bzeigl Posted June 28, 2021 Report Share Posted June 28, 2021 I want to run a cable to connect a V130 to a computer for data acquisition. The cable will have to be about 100' long. Will the RS 232 still work at this distance? Quote Link to comment Share on other sites More sharing options...
AlexUT Posted June 28, 2021 Report Share Posted June 28, 2021 You can find all information at Internet (Google or other search engine). It is recommended to use RS485 interface instead of RS232 interface. Quote Link to comment Share on other sites More sharing options...
MVP 2022 kratmel Posted June 28, 2021 MVP 2022 Report Share Posted June 28, 2021 In real field installation - RS232 with shielded cable can work at full speed for approx 20-50m. Best way - use isolated RS485 (port 2) card inside V130 and use isolated PC USB to RS485 converter. In this case on the lower speed (9600) and even with unshielded cable - distance can be approx 1200m. At high speed - shielded twisted wire (only two twisted conductor inside) cable recommended but distance approx 500m is possible or even more. Ideal solution - use optical RS232 extender but it is not cheap solution. Quote Link to comment Share on other sites More sharing options...
