example of each type of advisory:
Note: The note is used to present special instruction, or to provide extra information which may
help to simplify the use of the product.
CAUTION!
A Caution is used to alert you to a situation which if ignored may cause injury or
damage equipment.
WARNING!
A Warning is used to alert you of a situation which if ignored will cause serious
injury.
Cautions and Warnings are accented with triangular symbols. The exclamation symbol is used in all cau-
tions and warnings to help alert you to the important instructions. The lightning flash symbol is used on the
left hand side of a caution or a warning if the advisory relates to the presence of voltage which may be of
sufficient magnitude to cause electrical shock.
Use caution when servicing any electrical component. We have tried to identify the areas which may pose
a Caution or Warning condition in this manual; however, Industrial Computer Source does not claim to

How to remain CE Compliant
In order for computer systems to remain CE compliant, only CE compliant parts may be used. To
keep a chassis compliant it must contain only compliant cards, and for cards to remain compliant
they must be used in compliant chassis. Any modifications made to the equipment may affect the
CE compliance standards and should not be done unless approved in writing by Industrial Com-
puter Source.
The SB686P (V) is designed to be CE Compliant when used in an CE compliant chassis. Maintain-
ing CE Compliance also requires proper cabling techniques. The user is advised to follow proper
cabling techniques from external devices to the interface to ensure a complete CE Compliant sys-
tem. Industrial Computer Source does not offer engineering services for designing cabling sys-
tems. Although Industrial Computer Source offers accessories, it is the user's responsibility to
ensure they are installed with proper shielding to maintain CE Compliance.

This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause harmful inter-
ference to a radio or television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or more of the following
measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and the receiver.
•Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected.

Watchdog Timer
The watchdog timer is a hardware timer which resets the processor board if the timer is not
refreshed by software periodically. The timer is typically used to restart a system in which an
application becomes hung on an external event. When the application is hung, it no longer
refreshes the timer. The watchdog timer then times out and resets the processor board.
The watchdog timer has two levels of enable. First, the watchdog timer jumper must be moved
to the “enabled” position, which puts the watchdog timer under software control.
The second level is done in two phases. First, access to the watchdog timer gate, ADRx, via a
user-definedI/Oportmustbeenabledandconfiguredinregisters3,8and9oftheFDC37C665GT
