Installation Procedure
Installation
When the cable is pulled through the
center of the extension mast, it is
recommended that RTV silicon sealant be
used to seal off the cable slot on the
bottom of the receiver to protect it from
the environment. When the cable is pulled
out through the slot, secure it in position
to protect it against damage due to
vibration. Then seal the slot on the receiver
bottom with the RTV silicon sealant.
Avoid thread damage Grip and turn from the base

The aluminum bottom of the GPS112/DGPS212 are designed so that it can
be installed on the navigation antenna mount unit or on an extension mast
conforming to 1” x 14 NPT standards. The aluminum casing is negative earth, so
a plastic mounting unit should be used to prevent any corrosive activity from
developing. The bottom of the receiver is provided with a slot to allow the
receiver cable to be pulled out to the side. This eliminates the need of pulling the
cable through the center of an extension mast.
When twisting on the receiver be careful not to damage the cable.
Insluate the GPS/DGPS sensor case from ground.
Without insulation, a considerable amount of
current frow from ground to this equipment.
A considerable amount of current may cause
equipment damage.
