3.5.7 Bonding between chassis mounting point and airframe installation

to be <0.1 ohm resistance using <50 ohm impedance cable. No

surface prep is required due to conductive chassis (except front

bezel).

3.6 Electrical Characteristics

3.6.1 Electrical Specifications

3.6.2 Typical interfaces include various AES-3 distribution and/or signal

manipulation devices. This unit is capable of interfacing and

providing output to compatible Audio International devices capable

of distributing and/or processing the source output digital audio

including, but not limited to: Audio routers, stand-alone AES-3

decoders, and audio power amplifiers with built-in AES-3 decoding

capability.

3.6.3 The MCD-9101-101-x utilizes one (1) 25-pin connector for electrical

connections, which provides power, data bus control, infrared input,

and three (3) ID address pins and a common ID for unit

identification on the RS-485 data bus and for IR control.

3.6.4 Infrared input provides a ground reference connection (-). For

optimum infrared signal transmission, this ground reference should

connect to the module being utilized.

3.6.5 The three (3) ID address pins can be connected to the ID common

to provide address configuration, on the RS-485 data bus. This
