RS-232/RS-485/422 Interfaces
Electrical Interace Selection
The Xtreme/104 Opto adapter provides jumper selectable RS-232
and RS-485/422 electrical interfaces on each port.
Jumper blocks JB4, JB5, JB6 and JB7 set the electrical interfaces
for the individual ports, with JB4 for Port 1; JB5 for Port 2; JB6
for Port 3; and JB7 for Port 4. Jumpers installed across position B
on JB4, JB5, JB6 and JB7 enable the RS-232 interface for that
port, while
jumpers not installed across position B enable the RS-
485/422 interface for that port . Figure 1 shows the locations of
jumper blocks JB4, JB5, JB6 and JB7.
Example 1 This example shows the settings on JB4 and JB5
jumper blocks so that port 1 is set for RS-232
and port 2 is set for RS-485/422.

KBPS, but you must use good quality serial cables with lengths
that do not exceed 2 metres.
