Chapter 4: Powering the DL422
The DL422 provides power to the connected Instruments, GPS, and Radio.
Total power input to the DL422 is dependent on the quantity and types of
instruments connected.
The wire size used for the power connector must be sized to handle the
maximum current requirements of the DL422 circuit board plus the
instrument(s), GPS, and Radio power requirements.
DL422-E-Series
The DL422-E-Series receives power through the 3-pin power connector. A mating 3-socket
connector is packaged with the DL422-E-Series unit. The user is responsible for correctly attaching
the wires from an appropriate rated and certified power source to the mating connector, and for
properly sealing the connector-to-cable interface.
The largest wire accepted by the 3-pin circular power mating connector is 20 AWG.
The input voltage range is 5V to 60V, and can be sourced from an external power supply or battery.

The descriptions in this section refer to labels imprinted on the DL422 circuit board. An image of the
circuit board is shown at Figure 8, Chapter 6, below.
Power Block
The DL422 circuit board is powered through the (J4) screw terminal connector labeled “V_IN”. The
DL422 provides power to the connected instruments, GPS, and Radio.
The largest wire accepted by the screw terminal connector (J4) is 18 AWG.
The input voltage range is 5VDC to 60VDC and can be sourced from an external power supply or
battery. There are two input terminal each for power and ground. These pins are connected and can
be used for daisy-chaining power connections with other devices.
