- Page 6 Statement 0001/WARNING: The power supply provided by Septentrio (if any) should not be replaced by another. If you are using the receiver with your own power supply, it must have a double isolated construction and must match the specifications of the provided power supply.
- Page 7 Electronic components and assemblies, such as Septentrio OEM receivers, can be permanently damaged or destroyed when near or in contact with electro-statically charged objects. When you handle components or assemblies that are not in protective bags and you are not sure whether they are static-sensitive, assume that they are static-sensitive and handle them accordingly.

Page 10: Antenna Connectors
AsteRx4_OEM 2.2 Antenna Connectors Type: MMCX, right angle DC voltage: As provided by pin#14 of the 80-pin connector Gain range: 15 dB to 50 dB (antenna gain minus cable losses) The right-angle MMCX connectors are mounted on the bottom side of the board and protrude 1.2mm beyond the edge of the PCB. - Page 11 AsteRx4_OEM Sleep/off mode can be detected by the fact that the voltage at pin#29 (VCC_3V3_OUT) is zero. Pin#29 can be used as an “enable” for the drivers driving the input pins. When pull-up resistors are needed, 10k is recommended. Always pull-up to 3.3V even when using another voltage at the Vin pins.

AsteRx4_OEM 2.4 Frequency Reference Selection The receiver can get its 10-MHz frequency reference from its internal TCXO, or from an external reference source. The clock selection is controlled by the EXTREF_STAT pin (pin#55), as follows: EXTREF_STAT pin level Reference clock Signal at REF_O pin (pin#39) source Pin left open (there is... -
Page 15: Usb Device
AsteRx4_OEM USB Device The user can configure the USB bus (pins#3 and #5) in either USB 1.1 (full speed) mode, or in USB 2.0 (high speed) mode. USB 2.0 allows higher bandwidth, but may not be supported by all host hardware. By default, the USB bus is configured in USB 1.1 mode. -
Page 16: Sd Memory Card Usage
AsteRx4_OEM After having requested to enter stand-by mode, it takes up to 0.5 seconds for the receiver to actually enter low-power state. This time is required to unmount the SD memory card (if applicable) and to stop all software activities. Waking up from stand-by mode is done in one of the following ways: 1. -

Page 23: Antenna Connector
AsteRx4 Evaluation Kit 3.4.7 Antenna Connector The interface board has no antenna connector, the antenna has to be connected directly to the main or aux MMCX connector of the AsteRx4_OEM board. When the jumpers are set in their default configuration as defined in section 3.2, a 3.3V- DC voltage is available at the antenna connector. - Page 24 Appendix A LED Status Indicators Appendix A LED Status Indicators A.1 AsteRx4_OEM LEDs The LED pins of the 80-pin connector (see section 2.3) can be used to monitor the receiver status. They can be used to drive external LEDs (max drive current 8mA). It is assumed that the LED lights when the electrical level of the corresponding pin is high.
- Page 25 Appendix A LED Status Indicators A.2 Interface Board LEDs The 28 red LEDs on the interface board report the current state of selected pins of the 80- pin connector. A LED lights when the electrical level at the corresponding pin is high. The following table indicates which pin of the 80-pin connector corresponds to each of the LEDs.
