DC Power and DC Power Control Connections
DC power to the DLC50 must be applied to pin A of the four-pin power connector. DC return (GND) is
connected to pin C of the four-pin power connector. DC input power to the DLC50 should be powered
from the same circuit breaker as the rest of the microwave system components, including any external
relays. The power switch on the DLC50 can control DC power to all components of the microwave
system when a Power Voltage Relay (PVR) is used as a power distribution hub for the microwave
system components. The PVR will provide continuous power to the DLC50. The DLC50, when
switched on, will signal (using the "system power on/off" signal on pin D of the 4-pin power connector)
the PVR to provide DC power to the connected equipment. BMS manufactures cable P/N 7314189010
to provide the power and power control connections between the DLC50 and the PVR. Contact BMS
Customer Service for more information.

Transmitter Connections
Transmitter connections to the DLC50 are generally limited to RS232 serial port COM2. Transmitter
commands from the DLC50 to the transmitter are output on pin 4 of the 25 pin I/O connector. Status
back from the transmitter will come back to the DLC50 on pin 5 of the 25 pin I/O connector. Data
ground for the COM2 serial port is on pin 6 of the 25 pin I/O connector. CCII and HCII transmitters have
the ability to daisy-chain RS232 signals. The CCII/HCII serial connections are labeled PC Status, and
PC Command. CTxx40ARINC-HD transmitters use DATA_TX as status, and DATA_RX as command.
In addition, the CTxx40ARINC-HD transmitter requires a switched 5V and switched 28V signal to be
provided by the DLC50 controller. Switched 28V is available on pin 16, and switched 5V is available on
pin 15 of the 25 pin I/O connector. Signal return (GND) for the switched voltage signals is available on
pin 21. Do not attempt to power any devices from the switched 28V or switched 5V outputs from the
DLC50. These are signal level only. The transmitter type must be set up in the configuration menu. See
Configuration section.
