COM2/ 3/ 4 Port Configuration
The system
’s
COM2/ 3/ 4 ports
support RS-232 (full-duplex) while COM2 also
supports RS-422 (full-duplex) and RS-485 (half-duplex) mode. The operating mode
can be configured via the
BIOS. Another option in BIOS called “
Slew Rate
” defines
how sharp the rising/falling edge is for the output signal. For long-distance
RS-
422/485 transmission, you may set the “
Slew Rate
” option as “High” to improve
signal quality. For RS-422/485 communication, the
“
RS-422/485 Termination
” option
determines whether to enable/disable internal termination of RS-422/485 transceiver
according to your wiring configuration (e.g. with or without external termination).
To set COM2/ 3/ 4 operating mode:
1.
Press
F2
when the system boots up to enter the BIOS setup utility.
2.
Go to
[Advanced]
[Peripheral Configuration]
.
3.
Set the
[Set COM2/ 3/ 4 Mode as]
option to the desired mode.
4.
Once set, press
F10
to save setting and exit.
