(2) Reserved and Spare Wires
(a) If the installer does not wish to connect all wires, he can select wires reserved for
optional functions which his system does not contain and delete these wires. He
must also decide which future spare wires to include in the installation. Reserved
and spare wires are identified in interwiring diagram Figure 2006.
(3) Source/Destination Identifier (SDI) Encoding
(a) A connection is required from the common pin MP6C to the appropriate
source/destination identifier (SDI) pin to identify each DMA-37B in multiple system
installations. Installations having only one DMA-37B must include a connection
identifying it as the No. 1 system. These connections must not be omitted from any
installation. See Figure 2006 notes for the SDI encoding scheme for pins MP1C,
MP1D, and MP1E.
D. Installation of System
(1) Mounting Base
(a) The selected mounting base for the DMA-37B DME Interrogator must be wired
according to the system interwiring diagram, Figure 2006, and installed according
to the manufacturer’s instructions. The mounts are designed to be removed without
rewiring the connectors. Follow the equipment manufacturer’s installation
instructions to install the mount into the airframe.
(b) To wire the mounts into the system, first remove the mount connector cover and
connector plate assembly. Then crimp or solder (as applicable) the interconnecting
wiring to the appropriate connector pins. Finally, return the connector plate
assembly and cover to their original positions.
NOTE: To allow for inspection or repair of the connector, or the wiring to the
NOTE: To allow for inspection or repair of the connector, or the wiring to the
connector, sufficient lead length must be left so that the rear connector
assembly can be pulled forward several inches when the mounting
hardware for the rear connector assembly is removed. A bend must be
made in the harness near the connector to allow water droplets, that might
form on the harness from condensation, to drip off at the bend and not
collect at the connector.

Input/
Output
Suppressor
This analog port is both an input and an output.
When the DMA-37B is receiving, this line will
receive suppression pulses from other pulse
equipment, and when the DMA-37B is
transmitting, this line will transmit suppression
pulses to other pulse equipment.
BP13
Output Reserved for Video Output
Output for the video output signal from the
DMA-37B receiver.
