OEM6 family cards contain a DC-to-DC converter, tolerant to input noise and ripple. A tightly regulated
input supply is not required, as long as it falls within the given input range. The power supply used for any
OEM6 family card should be capable of providing the specified power requirements stated in
Voltage Input Requirement for OEM6 Family Cards
.
Table 2: Voltage Input Requirement for OEM6 Family Cards
for further information.
The OEM6 family cards also provide protection during a voltage event of short duration. It is
recommended that appropriate fuses or current limiting be incorporated as a safety precaution on all
power lines used. Use a sufficient gauge of wire to ensure the voltage at the connector is within the
OEM6 family card’s requirements.

Card Installation Overview
When the appropriate equipment is selected, complete the following steps to set up and begin using the
NovAtel GNSS receiver.
1. Install the OEM6 family card in an enclosure with a wiring harness (refer to
OEM6 Family Card with Wiring Harness and Enclosure on page 26
2. Mount the GNSS antenna to a secure, stable structure.
3. Connect the GNSS antenna to the receiver using an antenna RF cable (refer to the information in
Section 2.3.3 Connecting the Antenna to the Receiver on page 24)
.
4. Apply power to the receiver, as described in
Section 2.5.2 Applying Power to the Receiver on page
.
5. Connect the receiver to a computer or other data communications equipment (refer to
Connecting Data Communications Equipment on page 30
for instructions).
If the voltage supplied is below the minimum specification, the receiver suspends operation.
If the voltage supplied is above the maximum specification, the receiver may be
permanently damaged, voiding the warranty.
