2 INSTALLATION
Mechanical installation of the DLC50 in the aircraft requires 1.5" of vertical space in a standard
MS25213 aircraft equipment panel. Dzus ¼-turn fasteners lock the DLC50 into the stardard rails.
Installation location should allow for easy operator viewing and operation.

2.1
Installing the DLC50 (replacing an HCP50-II)
Installing the DLC50 as a replacement for an HCP50-II in an existing installation is very simple. Power
and Actuator cables are the same and can connect directly to the power and actuator connectors on
the rear panel of the DLC50. The I/O connector has been expanded to 25 pins and requires an adapter
to connect to the wiring harness in existing HCP50-II installations.
1. Connect the appropriate adapter cable, listed below, from the 10-pin connector of the existing wire
harness to the 25 pin I/O connector on the DLC50. BMS provides the following cables for these
connections:
a. 7314395011 – DLC50 TO HCP50 ARINC (used when DLC50 replaces an HCP50 with a
CTxx40ARINC transmitter)
b. 7314395012 – DLC50 TO HCP50, CCII/HCII (used when DLC50 replaces an HCP50 with
a CCII/HCII transmitter)
2. Connect the power and actuator cables to the appropriate rear-panel connectors.
3. Position the DLC50 into its mounting slot in the control panel and turn fasteners ¼ turn to lock in
place. Consult Figure 5 for nominal panel size and dimensions.
4. Secure wire harness and adapter.
2.2
Installing the DLC50 (new installation)
A new installation of the DLC50 will vary depending on the types of microwave hardware to be
controlled in the system and how much of the system wire harness has been already prepared by
BMS. (Contact BMS for assistance with wire harness design and prefabrication.) If the cable harness
has been prepared by BMS, then most connections will already be made in the harness. Additional
