Installation
RF cables, the performance specifications of the EuroPak-15ab receivers are warranted only when used with
NovAtel-supplied accessories.
2.1.3
10 MHz External Oscillator
The EuroPak-15ab receiver requires the use of a 10 MHz external oscillator. Choose an external 10 MHz
reference oscillator with a signal power level of +3 to +13 dBm.
Installation consists of connecting a cable from the external oscillator to the EuroPak-15ab's external oscillator
input connector.
The BNC external oscillator port, labelled OSC, is used for input signals on the EuroPak-15ab. See Figure 2 on
Page 23.
2.1.4
Power Supply Requirements
This section contains information on the requirements for the input power to the receiver. See Appendix A,
Technical Specifications starting on Page 112 for more power supply specifications.
WARNING: If the voltage supplied is below the minimum specification, the receiver will suspend
The receiver is designed to prevent internal damage when subjected to a reverse polarity power connection. It
also provides protection from short over voltage events. 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
that the voltage at the connector is within the receiver's requirements.
2.1.4.1
EuroPak-15ab Enclosure
The EuroPak-15ab is supplied with a 12 V power adapter with a built-in slow-blow fuse for use with a standard
12 VDC power outlet.
If a different supply is desired, the input range required is +9 to +18 VDC. The type of connector required to
mate with the receiver's power connector is a 4-pin LEMO socket connector labelled PWR. The supply should
be capable of 25 W. See Appendix D, Replacement Parts starting on Page 129 for the LEMO connector part
number.

Installation Overview
Once you have selected the appropriate equipment, complete the following steps to set up and begin using your
NovAtel receiver.
1. Mount the antenna or signal generator to a secure, stable structure, see Section 2.1.1 on Page 26
and Section 2.2.1 on Page 28.
2. Connect the antenna or signal generator to the receiver with an RF cable, using the information
given in Section 2.2.2 on Page 29.
3. Apply power to the receiver, as described in Section 2.2.3 on Page 29.
4. Connect the 10 MHz external oscillator, as described in Section 2.1.3 above and Section 2.2.4 on
Page 29
5. Connect the receiver to a PC or other data communications equipment by following the
information given in Section on Page 29.
