DeCrane Aerospace Audio International MCD-9101-101-x Installation & Operation ManualDocument # 540360, Rev IR, 03/2008 Page 11 of 283.5.6 The cover bezel snaps easily on the MCD-9101-101-x faceplatewithout the need of special tools. The cover bezel does not requiremounting bracket attachments.3.5.7 Bonding between chassis mounting point and airframe installationto be <0.1 ohm resistance using <50 ohm impedance cable. Nosurface prep is required due to conductive chassis (except frontbezel).3.6 Electrical Characteristics3.6.1 Electrical Specifications3.6.2 Typical interfaces include various AES-3 distribution and/or signalmanipulation devices. This unit is capable of interfacing andproviding output to compatible Audio International devices capableof distributing and/or processing the source output digital audioincluding, but not limited to: Audio routers, stand-alone AES-3decoders, and audio power amplifiers with built-in AES-3 decodingcapability.3.6.3 The MCD-9101-101-x utilizes one (1) 25-pin connector for electricalconnections, which provides power, data bus control, infrared input,and three (3) ID address pins and a common ID for unitidentification on the RS-485 data bus and for IR control.3.6.4 Infrared input provides a ground reference connection (-). Foroptimum infrared signal transmission, this ground reference shouldconnect to the module being utilized.3.6.5 The three (3) ID address pins can be connected to the ID commonto provide address configuration, on the RS-485 data bus.
