Although they are both configured for RS-232 standard, the configuration of the
top connector can be changed to accommodate the RS-485 standard by adjusting
the unit's BIOS setting. For information, refer to the BIOS appendix for the

The top serial port connector (labeled Com1/RS-232/485) in RS-485 mode is
not terminated by default. If your configuration requires that you instantiate
