RS-232/RS-422/485 Option 19

RS-232/RS-422/485 Interfaces

Electrical Interface Selection

The Xtreme/104 Opto adapter provides jumper selectable RS-232

and RS-422/485 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-422/485 interface for that port. Figures 1 and 2 show 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-422/485.

This example shows the settings on JB4, JB5, JB6 and JB7 jumper

blocks so that ports 1, 2 are set for RS-422/485 and ports 3, 4 are set

for RS-232.
