78 Appendix B: Technical reference
Serial port connectors
The 2 serial port connectors are 9-pin, D-subminiature male connectors (DB-9
1
).
Although they are both configured for the RS-232 standard, the configuration of
the top connector can be changed to accommodate the RS-485 standard by
adjusting the unit’s settings in the UEFI Setup utility. For information, refer to
Appendix C: Matrox 4Sight EV6 UEFI reference.
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
termination of the RS-485 connection, refer to the RS-485 termination connector
subsection of the Pinout descriptions of internal connectors section, later in this
appendix.
