2.2.2
Connecting the Antenna or Signal Generator to the Receiver
Connect the antenna or signal generator to the receiver using high-quality coaxial cable, as discussed in
Section
2.1.2
on
Page 26
.
The EuroPak-15ab provides a TNC female connector, which can be connected to the antenna or signal
generator directly with any of NovAtel’s coaxial cables.
2.2.3
Applying Power to the Receiver
Connect the power supply to the
PWR
port of the EuroPak-15ab receiver.
2.2.4
Connecting the Oscillator
Connect the 10 MHz external oscillator to the
OSC
port of the EuroPak-15ab receiver.
2.2.5
Connecting Data Communications Equipment
In order to communicate with the receiver by sending commands and obtaining logs, a connection to some
form of data communications equipment is required. The default configuration available for each of the
receiver types is given in the table below. Consult NovAtel Customer Service for more details on factory
configuration. See
Appendix A, Technical Specifications
starting on
Page 112
for data connection details.
Table 1: Default Serial Port Configurations
Each port supports some, or all, of the following signals:
•
Clear To Send (CTS)
•
Transmitted Data (TXD)
•
Request To Send (RTS)
•
Received Data (RXD)
The EuroPak-15ab enclosure is Data Terminal Equipment (DTE) so that TXD and RTS are outputs while RXD
and CTS are inputs. A null modem cable is required to connect to another DTE like a terminal or a PC.

Additional Features and Information
This section contains information on the additional features of the EuroPak-15ab receivers, which may affect
the overall design of your receiver system.
2.3.1
Strobes
A set of inputs and outputs that provide status and synchronization signals are given on the EuroPak-15ab.
These signals are referred to as strobes. As shown in
Table 2
on
Page 30
, not all strobe signals are provided on
all receivers. However, for those products for which strobes are available, you may want to design your
installation to include support for these signals.
The EuroPak-15ab enclosure provides strobe signals at its I/O port, as described in
Table 53
on
Page 116
.
Strobe signals include an input and several outputs as described below:
•
Mark Input (Event1)
A pulse on this input triggers certain logs to be generated.
(see
Section 4.2.2, Log Triggers
on
Page 37
).
•
Measure Output (MSR)
Falling edge is synchronized with internal GPS
