Note:
A pair of needle nose pliers may be helpful when working with jumpers. If
you have any doubts about the best hardware configuration for your application,
contact your local distributor or sales representative before you make any
changes. Generally, you simply need a standard cable to make most connections.
The jumper setting diagram is shown below. When the jumper cap is placed on both pins, the
jumper is SHORT. The illustration below shows a 3-pin jumper; pins 1 and 2 are short. If you
remove the jumper cap, the jumper is OPEN.
PIN 1-2 SHORT
PIN 3 OPEN
The picture below shows RS-232/422/485 (J8/J9) jumper setting.
Example:
To make RS-232 settings, set the Jumper 8 Pin 1-2 to the SHORT position, and Jumper
9 Pin1-2, 4-5, 7-8, 10-11 to the SHORT position.
