1 INTRODUCTION

The DLC50 (Figure 1) is a control panel for airborne microwave systems in rotary or fixed-wing aircraft.
It is user configurable for a large range of equipment and capabilities and is software upgradable. While
the DLC50 is intended to functionally replace the HCP50-II, its capabilities extend far beyond those of
the HCP50-II.

The DLC50 can control a transmitter, a receiver, an antenna actuator, RF Power Amplifier, and several
external relays. See Figure 2. Control of transmitter and receiver are accomplished via dedicated or
shared serial ports (user selectable).
Remote control of DLC50 is possible by connecting another DLC50 via the remote control port. The
remote DLC50 and the primary DLC50 will have equal priority control of all functions except the
antenna actuator which remains dedicated to the primary DLC50. Alternately, the primary DLC50 may
be slaved to an external flight computer for remote control, or a laptop may be used for direct access to
the transmitter and/or receiver for transmitter/receiver maintenance.
Updates of the DLC50 firmware may be made via the front panel serial port, while updates to channel
plans, presets, preferences, etc. may be made via the front panel USB host port using a USB thumb
drive. Configurations, preferences, and channel plans may also be saved to a USB thumb drive
connected to the USB host port. A generic system diagram is shown below.
