Interface Selection Jumpers
The ARTIC186 8-Port PCI Adapter has a set of jumpers used to select the serial interface used by each
port. The interface is selected on a port-by-port basis for each of the eight ports. The jumper selects
either an RS-232 or RS-485/422 interface for a given port; the default position is RS-232.
The following shows the location of the interface-selection jumpers.
Note: RS-422 is a subset of RS-485.
Set Port Protocol (RS-232 or RS-485): Position the shunt (a 2x5-position jumper) to select the
interface: RS-485 or RS-232. Each port can be configured independent of the setting of the other ports.
