ations for
connecting to
other devices
When interfacing to other devices, ensure the transmit data
output and the signal grounds from the VR1000 are connected to
the data input, and signal grounds of the other device.
The RS-422 is a balanced signal with positive and negative signals
referenced to ground; ensure you maintain the correct polarity.
When connecting the transmit data output positive signal to the
receive line of the other device, it should be connected to the
receive positive terminal.
The negative transmit data signal from the VR1000 is then
connected to the receive data negative input of the other device.
For a list of Hemisphere GNSS commands, please refer to the
Hemisphere GNSS Technical Reference Manual

unit through the WebUI, please refer to
Power/Data

The VR1000 uses a single 3 m cable for power and data input/
output.
The receiver end of the cable is terminated with an
environmentally-sealed 23-Pin connection while the opposite end
is terminated with multiple connectors. Ensure that the PWR-/B-
wire is connected to a clean chassis ground.
DO NOT
