Caution - Do not operate the Vector Sensor with the fuse bypassed. Such a
modification will void the product warranty.

2.7.6 Turning the Vector Sensor On

When connected to a suitable power source, the Vector Sensor may be turned on and off using
the ON/OFF switch located on the rear panel.
To turn the Vector Sensor on:
Ensure that the red wire of the supplied power cable is connected to DC positive (+).
n
Ensure that the black wire of the supplied power cable is connected to DC negative (-).
n
Connect the keyed, two-conductor socket connector of the power cable to the Vector Sensor.
n
Turn the Vector Sensor on, by pressing the ON/OFF switch located on the rear panel
n
To power the Vector Sensor down, press the ON/OFF button one more time instead of
disconnecting the power cable.

2.7.7 Connecting the Vector Sensor To External Devices

The dual serial ports of the Vector Sensor are compatible with the RS-232C interface level to
communicate with navigation systems and other devices.
You may use either the A or B port for operation of the system, however Port A should be used
for firmware updates. Either port may be used for the input of external differential corrections, if
desired. The Display Only port is present only for firmware upgrades of the secondary GPS and
for possible future expansion of the Vector Sensor with a display unit.
The following two tables provide the pin assignments for both ports.
