SplitBox – User Manual SPLI BOXUM.1.2
1. Introduction
he SplitBox from SBG Systems is a complementary accessory of the Ekinox and Apogee series. It provides
a simplified interface with standard connectors to ease both the setup and integration. It replaces the 19
pins Fisher Connectors of the Ekinox and Apogee by standards M-12, SMA, and DB-9 connectors
corresponding to each port.
he front face of the box gives access to the standard connectors, while the back face is connected directly
to the Ekinox or the Apogee using 5 meters cables.
1.1. SplitBox Versions
he SplitBox comes in different versions to meet all customer requirements. his manual is common for all
versions, so you should only look to the appropriate section of this document for your specific SplitBox.

1.2. Package content
In addition to the SplitBox module, a set of accessories and cables is included in the package to facilitate
user integration:
●International AC/DC power supply
●An Ethernet cable
●A set of NC / SMA / BNC adapters for synchronization signals
Note: In order to allow different cable lengths, the cables required to connect the Splitbox to an
Ekinox/Apogee should be ordered separately.

1.3. SplitBox Septentrio specifications (models -S)
he SPLI BOX-S D-S and SPLI BOX-SUB-S embed a very high end, survey grade, dual antenna, Septentrio
GNSS receiver that is perfectly fitted for the very demanding survey market.
It features L1/L2/L5 and L-Band signals tracking and uses GPS, GLONASS, BEIDOU and GALILEO
constellations to provide very accurate and reliable measurements even in harsh environments.
he internal dual L-Band demodulator supports errastar and Veripos Precise Point Positioning (PPP)
services to delivery world wide, with no specific infrastructure, a positioning accuracy better than 10 cm.
his latest generation GNSS receiver also features very accurate R K positioning with the world's leading
signal availability and minimal re-acquisition time after a GPS outage. With a refresh rate of 20Hz, this
receiver provides best accuracy and reliability in harsh GNSS environments thanks to a very advanced auto
mitigating algorithm that detects and eliminates multi-path situations or Inmarsat / Iridium jamming.

2. ypical connection diagrams
As a rule of thumb, all serial ports on the Ekinox/Apogee should be configured in RS-422 mode as the
communication between the SplitBox and the Ekinox/Apogee is using the RS-422 protocol. he RS-422
protocol is much more secure than the RS-232 especially over long distances.
Each SplitBox serial ports can however be individually configured, for RS-232 or RS-422 levels. his is done
using dedicated switched that are present on the back face of the SplitBox unit. Please refer to section
4.4 Configuration Switches for detailed information about switches usage and functions.
2.1. SplitBox without integrated GNSS
he SplitBox models without embedded GNSS receiver connections are quite straightforward, as all Ekinox/
Apogee ports map directly to a SplitBox port.
Warning: he subsea version doesn't support CAN communications. In addition, the Sync In C is not
available for subsea units.
2.2. SplitBox with GNSS (models -S or - )
On the SplitBox equipped with an internal GNSS receiver, the connections are also straight forward for all
ports except for the POR D.
As shown on the diagram below, the GNSS receiver COM3 is directly connected to the Ekinox/Apogee
POR D. his serial port is thus used by the Ekinox/Apogee to receive GPS data from the SplitBox to be
integrated into the navigation solution.
On the SplitBox side, the POR D has two functions that can be selected using the configuration switches
present on the back face of the SplitBox:
●GPS configuration, in this mode, the POR D Rx and x signals are directly connected to the internal
GNSS receiver COM 1. his serial link can be used to access and configure the GNSS receiver.

●R CM input, in this mode, the POR D Rx is connected to the internal GNSS receiver COM2 Rx so
differential correction data can be sent to the internal GNSS receiver for real time R K. Please note
that in this mode, the POR D x is sill connected to the GPS 1 x signal.
Note: Whatever the POR D function is, the POR D x is always connected to the internal GNSS
receiver COM 1. his is very useful if you would like to use the POR D to input R CM corrections
while sending GGA frames @ 1 Hz from the GNSS receiver.

3. Internal GNSS receiver configuration
he 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 POR D)
●COM 2 is set to 38 400bps and accepts R CM 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 rimble GNSS receiver with the Ekinox
and Apogee series, please refer to the Septentrio and rimble Integration Operating Handbooks.
4. Interface
his section describes the different connectors and indicators available on the SplitBox.
4.1. Front face
his face brings one connector for each port of the Ekinox / Apogee. he Ethernet, POR A, B, C, E, and CAN
connectors are linked to their Ekinox/Apogee counterparts.
he POR D has a different function depending on the SplitBox model. For the one without an internal
GNSS receiver, the POR D is directly connected to the Ekinox/Apogee but for the SplitBox with an
integrated GNSS receiver, the POR D is either used to input R CM 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. he Sync Out is generally used to output a PPS signal to third part equipment.

SplitBox – User Manual SPLI BOXUM.1.2
4.2. Back face
he back face includes the connectors to connect the Ekinox/Apogee to the SplitBox as well as a DC input,
to provide power to the SplitBox and the Ekinox/Apoge.
A master power switch controls the whole system power supply. On the bottom right corner, an eight ways
configuration switch is used to change the SplitBox behavior.
Finally for SplitBox with an internal GNSS receiver, the Main and Secondary GNSS antennas can be
connected using standard NC connectors.
4.2.1. Version Standard (S D)
On the standard version, 3 cables are used to connect the SplitBox to the Ekinox/Apogee.
4.2.2. Version Subsea (SUB)
On the Subsea version one single cable is used to connect the SplitBox to the subsea Ekinox.

4.3. Status LED Description
hose LEDS inform you about the GNSS receiver function as well as general status display.
4.3.1. Power LED
his LED turns red when the SplitBox is powered on.
4.3.2. Satellite LED
he main behavior of this led is: green when the GNSS board has a valid position and red when
entering R K mode.
4.3.3. Sync Out LED
his LED reflects the signal present on the Sync Out B.
Note: Please not that the default Sync Out B signal level is HIGH. If no Sync Out B signal is
configured on the Ekinox/Apogee or at startup, the signal level will thus be HIGH.
4.3.4. Network LED
he Network LED reflects the status of the Ethernet Link between the SplitBox and the user's
network. It turns green when a link is established and yellow when data is being transferred.
