3. Internal GNSS receiver configuration
The embedded GNSS receiver is shipped with a pre-configuration that allows easy connection to the
Ekinox / Apogee.
●
Ethernet interface is configured in DHCP mode
●
COM 1 is set to 115 200 bps (Used for external configuration through Splitbox PORT D)
●
COM 2 is set to 38 400bps and accepts RTCM input
●
COM 3 is set to 460 800 bps for GPS data input to Ekinox / Apogee)
●
PPS Signal is sent at 1Hz, with a Rising Edge polarity.
Note: For more details about how to interface a Septentrio or Trimble GNSS receiver with the Ekinox
and Apogee series, please refer to the Septentrio and Trimble Integration Operating Handbooks.
4. Interface
This section describes the different connectors and indicators available on the SplitBox.
4.1. Front face
This face brings one connector for each port of the Ekinox / Apogee. The Ethernet, PORT A, B, C, E, and CAN
connectors are linked to their Ekinox/Apogee counterparts.
The PORT D has a different function depending on the SplitBox model. For the one without an internal
GNSS receiver, the PORT D is directly connected to the Ekinox/Apogee but for the SplitBox with an
integrated GNSS receiver, the PORT D is either used to input RTCM corrections or to have a direct full duplex
serial link to the internal GNSS receiver.
Finally, the front face also provides an easy access two SMA connectors for Sync In A (right) and Sync Out B
(left). Sync In signals are used to time stamp data such as a PPS input signal from an external GNSS
receiver or for event markers. The Sync Out is generally used to output a PPS signal to third part equipment.
