Rabbit RabbitCore RCM5400W, User Manual, Page: 85 / 120

OEM User’s Manual 79
It is recommended that you allow for an “exclusion zone” of 0.04" (1 mm) around the
RCM5400W in all directions when the RCM5400W is incorporated into an assembly that
includes other printed circuit boards. An “exclusion zone” of 0.08" (2 mm) is recom-
mended below the RCM5400W when the RCM5400W is plugged into another assembly.
Figure A-2 shows this “exclusion zone.”

NOTE: There is an antenna associated with the RCM5400W RabbitCore modules. Do
not use any RF-absorbing materials in these vicinities in order to realize the maximum
range.
The RCM5400W modules were tested for heat dissipation over the specified operating
temperature range, and normal heat dissipation by convection was found to be adequate. If
you plan to use RCM5400W modules in a tightly enclosed space, additional forced-air
cooling will likely be needed.
If you are planning to mount your RCM5400W directly in a panel-mounted enclosure, the
RP-SMA antenna connector will extend outside the enclosure. Keep the thickness of the
enclosure plus washer and lock nut to less than 0.2" (5 mm) to make sure that the antenna
can be mounted securely in the RP-SMA antenna connector.
