Setting Velocity Mode:
Hook the unit up to your computer’s serial port.
Use a terminal program to interface with the unit.
Make sure the switch is in the up position so that the unit can receive computer commands.
Turn on unit. Wait for the startup message to appear on display.
Hit the space bar twice within the first 5 seconds of turn on.
Sometimes it takes a few tries to get the hang of this.
Wait for the data string to start transmitting.
Now the unit will take in keyboard commands.
To set the velocity mode, type &.
This will bring up the menu:
Typing in 5' will bring up this menu:
To set to GPS Ground Velocity type ‘1’. This is the mode when using the GPS module. After this is set up the switch
needs to be in the down position. In this mode, the GPS module may still need to be switched on to provide heading
data.
To set to Analog Velocity type ‘2’. This is the normal DMS mode (non-GPS). Make sure that the proper analog
velocity signal is applied. In this mode, the GPS module may still need to be switched on to provide heading data.
To make this selection the default the next time you power the unit on type in " (double quote)
Setting Heading Calibration:
Hook the unit up to your computer’s serial port.

Now the unit will take in keyboard commands. Align the vehicle such that forward points accurately to True North.
The GPS antennas must be accurately spaced, but may be aligned to any heading with respect to the vehicle forward
vector. To calibrate the heading, type “G”, only uppercase will be accepted.
It is ESSENTIAL that this be done if the antennas are not physically aligned to the vehicle forward vector. Failure to
do this may have serious consequences on dynamic error corrections.
