Getting Started 23
Getting Started
1. Connect the female plug on the power cable to the J301 male connector on
the DG16.
2. Connect the power cable to the power supply.
Once power is connected, the LED on the DG16 Board flashes red.
When you apply power to the power input pins on connector J301, the DG16
starts operation.
When you remove power from the power input pins on connector J301, the DG16
stops operation.
Sensor
The power for the DG16 Sensor connects through the serial connector on the unit.
1. Connect the serial cable to the serial port on the DG16.
2. Connect the power cable to the serial cable.
3. Connect the power cable to the power supply.
Once power is connected, the LED on the DG16 flashes red.
Antenna
The DG16 is designed to work with an antenna Low Noise Amplifier (LNA) that
requires five volts and is isolated from DC ground. The gain of the antenna LNA
minus the loss of the cable is between 20 and 30 dB. Table 2.1 outlines the
antenna requirements.
CAUTION
To avoid damage to the DG16, always connect to cable to the DG16 Sensor
before connecting the cable to the power source, and turn off the power
supply before connecting or disconnecting power to the DG16.
