Hughes 9300 Series Installation Guide
Basic Installation Procedure
While the installation of the Hughes 9300 Series mobile satellite terminal is
straightforward, it is essential that the installation be done correctly.
The basic installation procedure is as follows:
1.
Decide where you are going to install the antenna and IDU.
2.
Ensure that the IDU is located inside the vehicle and attached to something
structurally solid. Loose mounts that vibrate will degrade performance.
3.
Determine the cable length required for the power installation.
4.
Perform the installation of the antenna and IDU.
5.
Connect the antenna via the three magnetic mounts to the vehicle’s roof or
permanently mount using screws/bolts.
6.
Connect the RF cable to both the IDU and antenna TNC connectors.
7.
Connect the power to the IDU.
8.
Properly ground the IDU.
9.
Power up the IDU/antenna.
Vehicular Installation
Installation – General
1.
Whenever routing cable through holes drilled in metal or through bulkheads, use
grommets and RTV sealant to weatherproof all holes drilled on the outside of the
vehicle.
2.
Use cable ties every 30–45 cm (12"–18").
3.
The IDU can be mounted in either the horizontal or vertical position.
4.
The main power line must be connected to a fused 12 or 24 VDC power source.
The unit is fused, but a 10 A or greater fuse is required in the source to protect
against shorts in the cabling. If connecting to a circuit in the fuse box already in
use, ensure that the circuit can supply the extra 6 A at 12 V or 3 A at 24 V for the
unit and increase the fuse value by 10 A at 12 V or 5 A at 24 V. If using the car
adapter cable, it already includes the fuse in the adapter.
5.
Route and connect the white Ignition Sense wire to a switched 12 or 24 VDC
source.
6.
Ground the IDU to the vehicle via a wire connected to the IDU ground wing nut.
7.
Install the IDU in a protected but ventilated area. Allow at least a 1 inch space
around all surfaces, except for the bottom surface attached to the vehicle, to
provide adequate cooling. Ensure that the location is accessible for servicing.
8.
The IDU is not waterproof.
9.
Always provision the wiring into the IDU with a drip loop.
