spring washer to attach the surgeprotectorrsquos grounding cable to thebracket (see Figure 4) Apply torque21[Nm] (192 [lbsin])

Make sure that the femaleconnector faces the antenna

5 Connect the surge protector cable(female connector) to the GPSantenna connector (male) Use thegroove on the cable connector(indicated by an arrow) as a guide

It aligns with the tenon in theconnector on the GPS side Turnthe locking ring on the cableconnector clockwise to secure theconnection Do not over-tighten

Preparing the IDU-ODU Cable

Use a crimp tool for RJ -45 connectors to prepare the wires Insert them into the appropriate pins and use the tool to crimp theconnector Make sure to do the following

bull Remove as small a length as possible of the external jacket Verify that the external jacket is well inside the sealingcover when connected to the unit to ensure good sealing

bull Pull back the shield drain wire before inserting the cable into the RJ -45 connector to ensure a good connection withthe connectors shield after crimping

For detailed instructions refer to the Preparing the Indoor-to-Outdoor GPS Cable instructions supplied with the Cat 5E GPScable
