1.1 Rear Panel Connectors
The rear panel features three connectors.
Note that two additional connectors may be present on your receiver. These additional connectors are
not connected.
1.1.1 MAIN (TNC)
Connect an active GNSS antenna to this connector. The gain at the connector (antenna gain minus
cable losses) must be in the range 15 to 50dB.
By default, the receiver provides a 5V DC supply on the MAIN connector to feed the antenna. Other
voltages can be imposed through pin ANT_EXT of the IN connector on the front panel (see section
1.2.6). The maximum supported current is 200mA.

_______________________________________________________________________ 1 PolaRxS_PRO
PolaRxS Product Family Hardware Manual v1.3.0 7
Never inject a DC voltage into the MAIN connector as it may damage the receiver. For instance,
when using a splitter to distribute the antenna signal to several receivers, make sure that no more than
one output of the splitter passes DC. Use DC-blocks otherwise.
1.1.2 PPS OUT (BNC)
xPPS output (5V, output impedance 50Ohms). The rate and polarity of the xPPS output signal are
specified by the setPPSParameters command. The pulse duration is 1.2ms.
1.1.3 REF OUT (BNC)
This connector provides access to the 10-MHz reference signal from the internal ultra low noise
OCXO. It is a sinusoidal signal with an unloaded peak-to-peak amplitude of 1.1V. Output impedance
is 50 Ohms.

This 7-pin connector can be configured in two modes:
COM3 and COM4 mode
USB mode.
The electrical level at pin#7 defines the operating mode.
1.2.3.1 COM3-4 mode
This mode is selected by leaving pin#7 unconnected.

7
ANT_EXT, external antenna power. Can be used to apply an external supply
voltage to the antenna. The voltage applied to ANT_EXT (VANT) determines the
voltage source on the MAIN and AUX1 connectors, as follows:
if VANT<2.0V or ANT_EXT left open, the antenna is powered by the internal
5V supply;
if 3.0V<VANT<4.0V, there is no power provided to the MAIN connector;
if 5.0V<VANT<12.0V, the antenna power supply is taken from ANT_EXT.
Warning:
Exceeding 12.0V for VANT, or drawing more than 200mA from the antenna
connector can permanently damage the receiver.

1.6 Internal Logging on SD Memory Card
The receiver incorporates a SD memory card for internal logging. Refer to the “How-to…” section of
the Firmware User Manual to learn how to use this feature.
To prevent data corruption, logging is protected against accidental power outages. There is no need to
unmount the SD memory card before switching off the receiver.
1.7 Applicable Software Package
The PolaRxS_PRO is compatible with Septentrio’s SSRC3 Software Packages.
1.8 Hardware Specifications
Power consumption: Nominal operation: 6.5W typical
During initial OCXO warm-up: up to 10W.
