However, because both connectors are DTE, the wiring is the same, so only a gender changer is needed to convert a cable between the two ports.įor details on using the serial port with RMCWin, see Using with RMCWin.įor details on using the serial port with the RMCCOM ActiveX control, see Using with the RMCCOM ActiveX Control. Early production RMCs have a female DTE DB9. There are two versions of the serial port for the RMC product. Communication over this port is always at 38400 baud with eight (8) data bits, no parity, and one (1) stop bit. The RMC100 CPU module has a DTE DB9 serial port labeled "RS-232 Monitor."
