Connection Example to Programmable Terminal (PT)
Direct Connection from RS-232C to RS-232C
• Communications Mode: NT Link (1:N, N = 1 node only)
• OMRON Cables with Connectors: XW2Z200T (2 m)
XW2Z500T (5 m)
RS-232C Port Specifications
Note
Baud rates for the RS-232C are specified only up to 19.2 kbps. The FQM1
supports serial communications from 38.4 kbps to 57.6 kbps, but some com-
puters cannot support these speeds. Lower the baud rate if necessary.
