AirCell ST 3100, Руководство по установке

Страница: 15 / 59

Note
ST 3100 part number 400-01680-001 has a Plain Old Telephone System (POTS) interface and
the 400-10680-002 has no POTS interface. These transceivers are identical including revision
levels; the only exception is the -002 configuration lacks a POTS module installed on the
motherboard.
Note
Component Bonding
As with any communication equipment, bonding the equipment to ground is essential for optimum
performance. Ensure that the Receiver/Transmitter Mounting Tray is bonded to the shelf, and the
shelf is bonded to airframe ground. Properly bonded, there should be 2.5 milliohms or less
between the Mounting Tray and airframe ground. Care in bonding has been shown to eliminate
erratic or poor system performance.
Note
Access Door for Audio Level, Side Tone Adjustment, and Mic Bias
Installation of multiple Handsets may require audio level adjustments for each Handset. Access
the 14 turn potentiometers by removing the small cover at the top of the unit. Use caution as the
two (2) screws are not captive and can be easily lost. The adjustments are set to mid-range at
the factory. Refer to Section 4.7.1. for Audio Level, Side Tone Adjustment, and Mic Bias
adjustment details. Refer to Section 10.0 for the Wiring Diagram for details on the separate
Handset A, B, and C audio channels, and Audio Panel interface.
2.2.3. Satellite Patch Antenna (Standard Antenna Shown)
The AirCell
®
Satellite Patch Antenna is P/N 015-10306-
001. This antenna is a low profile Iridium/GPS antenna
that provides continuous coverage from 1565
Megahertz (MHz) to 1626.5 MHz for excellent Iridium
applications. Mechanical configuration is a spherical-
radius molded radome that provides enhanced
protection against rain, ice, and lightening strikes.
Qualified for high-speed military aircraft as well as
general aviation applications, it has a TNC Female
connector.
Figure 2.6. Satellite Patch Antenna
Requirements of the applicable FARs may stipulate that proper Designated Engineering
Representative (DER) engineering documents (8110-3) be supplied or that the installation be
performed in accordance with an acceptable Supplemental Type Certificate (STC) for mounting
these types of antennas. These are the responsibilities of the Installer.
Note
Antenna Bonding
As with any communication equipment, bonding the Antenna to airframe is essential for optimum
performance. Ensure that the antenna is bonded to the aircraft skin. Properly bonded, there
should be 2.5 milliohms or less between the mounting screws and airframe ground. Care in
bonding has been shown to eliminate erratic or poor system performance. Iridium Antenna
bonding is essential for proper performance (as with any antenna).
