Hi all,
I built a converter for the RS422 (replaced CPM1CIF-11) communication between CPM1A and NT31-xxxx.
I do not know why it wants to communicate CPM1A. NT31 sends data to and receiving communications CPM1A flashes but does not send the CPM1A NT31 nothing. Anybody knows what could be the problem?
I built a converter USB/RS232 (replaced CPM1 CIF-01) for CPM1A and PC, and it works just perfectly.
