Serial ports

The 650 has three external RS232 serial ports, two of which can be powered COM2 and COM3. The serial ports are standard PC RS232 ports with a DB9 male connector. The serial ports, in a normal configuration, are mapped to COM 1-3.

COM ports 2 and 3 can supply power to an external device when required, like the optional J2 Customer Display. Voltage, +12, is supplied on pin 9 (RI) of the DB9 connector. The maximum current is 500ma and is over-current protected. To enable the voltage supply for either COM ports 2 or 3 the BIOS setup must be changed. This function can be enabled in the Advanced Settings screen under Super I/O Configuration.

COM1 also supports RS422 and 485 signaling. This can be enabled in the Advanced Settings screen under Super I/O Configuration in the BIOS setup screen.
