3.3 Installation Procedure
The base of the GPS124 is designed so that it can be installed on the navigation antenna mount unit
or on an extension mast that conforms to 1 x 14 NPT standards. 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. If the cable is fed through the center
of a mast, the cable connector will have to be removed.
Caution:
When turning the receiver, be careful not to damage the cable and the plastic top cover of the
receiver. (See Figure. 3-1.)
When the cable is fed internally through the extension mast, it is recommended that RTV silicon
sealant be used to seal off the cable slot on the bottom of the receiver as a protection from the
environment. If the cable is laid sideway through the slot, secure it in position to reduce the
damage by vibration. Then seal the slot on the receiver bottom with the RTV silicon sealant.
(See figure.3-2)

assignment. Incorrect pin connection may cause a damage of the equipment.
