Safety Precautions
For your safety carefully read all the safety instructions before using the device. Keep
this user manual for future reference.
Always disconnect this equipment from any AC outlet before cleaning. Do not use liquid or
spray detergents for cleaning. Use a damp cloth.
For pluggable equipment, the power outlet must be installed near the equipment and must
be easily accessible.
Keep this equipment away from humidity.
Put this equipment on a reliable surface during installation. Dropping it or letting it fall
could cause damage.
The openings on the enclosure are for air convection and to protect the equipment from
overheating.
Caution Do not cover the openings!
Attention Ne couvrez pas les ouvertures!
Before connecting the equipment to the power outlet make sure the voltage of the
power source is correct.
Position the power cord so that people cannot step on it. Do not place anything
over the power cord.
If the equipment is not used for a long time, disconnect it from the power source to
avoid damage by transient over-voltage.
Never pour any liquid into an opening. This could cause fire or electrical shock.
Never open the equipment. For safety reasons, only qualified service personnel
should open the equipment.
All cautions and warnings on the equipment should be noted.
Caution Always ground yourself to remove any static charge before
touching the board. Modern electronic devices are very sensitive to static
electric charges. As a safety precaution, use a grounding wrist strap at all
times. Place all electronic components in a static-dissipative surface or
static-shielded bag when they are not in the chassis.
Attention Mettez-vous toujours à la terre pour éliminer toute charge
statique avant de toucher la carte. Les appareils électroniques modernes sont
très sensibles aux charges électriques statiques. Par mesure de sécurité,
utilisez en tout temps un bracelet antistatique. Placez tous les composants
électroniques dans une surface antistatique ou dans un sac blindé
antistatique lorsqu'ils ne sont pas dans le châssis.
General Guideline
It is recommended to reboot the device when some functions are defect or inactive. If it still can't
solve the problems please contact your dealer or agent.
Special Conditions of Use
Winmate IBDRW100-EX-P is to be installed in an ATEX certified IP54 (as defined in EN 60079-
0 and EN 60079-15) enclosure and may be accessible only by the use of a tool. Provision shall
be made to prevent the rated voltage being exceeded by the transient disturbances of more
than 140% of the peak rated voltage.

2.2 Configuring COM2 Settings by Jumpers
Serial Port COM2 can be configured for RS-422 or RS-485 by jumpers. Jumpers are located on
the motherboard. You need to open the housing in order to access the jumpers.
Caution It is recommended to use factory jumper settings. Opening the
housing when it is sealed may damage the device and its parts.
Attention 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
Both Jumper 8 and Jumper 9 allow setting the Serial Port COM1 configuration. Refer to the table
