The rear of the receiver must have no less than a 1-inch air space from other
•
structure to allow proper airflow.
The area in front of the receiver must also accommodate the wiring. Up to 4
•
inches may be required for connectors, minimum wire bending radius and service
access.
A programming jack is provided in the installation kit of the product. This should
•
be installed in a convenient, easily accessible location to within 50 feet to the
receiver (Note: For multi-receiver systems, only (1) jack is required and is to be
connected to the receiver at node address #0). The jack consists of a DB-9
socket connector and mounting bracket and is intended to be connected to a PC
RS-232 Com port.
As per the applicable interface control drawing, the receiver is to be mounted
•
using the provided mounting holes. Typically the aircraft structure can be match
drilled, populated with nut plates or rivets, and machine screwed to secure the
receiver.

XMC Control Head
The control head can be surface mounted to a cabin interior finished surface or can be
flush mounted. For flush mounting, the overlay finish (fabricated by installer) must have
the appropriate cut-outs for the display, power switch and remote sensor. In both cases,
the control head is to be located and positioned so it is easily viewed and manipulated
by the user(s). In addition, the mounting area must accommodate the interconnect wiring
and connector to the rear of the control head.
Choosing the location with concern for the wiring distance from the control head
to receiver is not generally restricted. The placement of the receiver in relation to
the antenna is essential since this has a direct impact on signal performance.
The control head can also be controlled with a remote control device. Placement
of the control head should allow "line-of-sight" for all possible users in the cabin.
An auxiliary remote sensor can be connected if needed to "cover" some
passenger areas which are not in the "line-of-sight" to the control head face.
