Hi,
Does someone know how I can I connect RS422 port to my laptop. There are adapters to do so, but they are quite expensive. Is there anyway I can build the adapter by myself?
PS: The RS422 interface is located on a serial module (CP441) on a rack with Siemens S400 series CPU. The interface is used to connect a weigh scale to the PLC. But I cannot get the communication to work. So I am trying to connect it to my laptop for fault finding.
Any suggestion.
Thanks,
Samad
