Controllers • Interface Board
Resource settings (I/O address, interrupt) are made during the system start by the Plug & Play
BIOS and cannot be manually changed by the user (only with an ISA configuration utility or
Windows 95/98). If a resource is already assigned, BIOS attempts to assign configurations to the
interfaces COM3 and COM4 in the following order:
COM3, COM4
RS232/RS422 interface
electrically isolated
RS232 to 115 kBaud, RS422 to 19200 Baud
9 pin DSUB plug
Pin Assignment RS232 Assignment RS232

2 RXD
3 TXD

5 GND GND
