Serial Port Output Module
The module has up to four serial signals, each routed to a DB9 interface.
Each output can be configured as an RS-232 level or RS-422 level output.
The four-position DIP switch on the board is used to set the baud rate of the
serial port output. When pins 1 to 4 of the DIP switch are turned to "ON",
the status is "1", otherwise it is status "0". Pins 1 and 2 control the baud
rates of "COM1" and "COM2"; Pins 3 and 4 control the baud rates of "COM3"
and "COM4".
The correspondence between the DIP switch pin status and the serial port baud rate is as follows:
1, 2 Pin Status
COM1, COM2
Baud Rate
11
1200
01
2400
10
4800
00
9600
3, 4 Pin Status
COM3, COM4
Baud Rate
11
1200
