Default settings.
When the board comes from the factory,both ports are for RS-422.
Port 1 is set for DOS COM1(IRQ=4,base I/O addrss=3F8),and Port 2 is set for DOS COM2(IRQ=3,base I/O addrss=2F8).If you need to change these settings,see the following sections.Otherwise,you can simply install the card.Note that you will need to disable your CPU card's on-board COM ports,if any,or set them to alternate addresses/IRQs.
RS-422/485 selection (JP1 and JP2)
You can set each port indivdually for either RS-422(the default)or RS-485 operation.Jumper JP1 configures Port 1,and JP2 configures port2.The figure below shows the jumper settings.See the figeure on page 7 for help locating the jumpers.
(default)
I/O base address (sw1 and sw2)
You set the port base addresses using two six-position DIP switches,one for each port.Switch SW1 sets port 1,and SW2 sets port2.You can choose base addresses from hex 200to 3F8.The default settings are COM1(hex 3F8)for Port 1 and COM2(hex2F8)for port 2,shown below:
The following table shows the switch settings for various base addresses:
