2.3 Changing Serial Port Settings
Serial port COM1 can be configured for RS-232, RS-422 or RS-
485. Jumpers are located on the motherboard. You need to
open the housing in order to access the jumpers.
CAUTION/ ATTENTION
It is recommended to use factory jumper settings.
Opening the housing when it is sealed may damage the
device and its parts.
Il est recommandé d’utiliser la configuration d’usine de
cavalier. Ouvrir le chassis lorsqu’il est scellé peut
endommagé l’appareil et ses pièces.
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, pin 1-2, 4-5, 7-8, 10-11 to the SHORT position.
