2. Though the CCGX has no built-in WiFi that functionality can easily be added by attaching a
USB-WiFi dongle. See CCGX Manual, section 1.4.2 for details.
3. The built-in WiFi in the Venus GX has a very low signal strength - unfortunately. It is strong
enough to connect to a phone, tablet or laptop in order to access setup and monitoring. But to
connect the Venus GX to the internet either use the built-in Ethernet port or add a USB-WiFi
dongle. See CCGX Manual, section 1.4.2 for details. Make sure the Venus GX is running v2.06 or
later - early shipments of Venus GX units ran v2.05.
4. The hardware of the Venus GX and Octo GX includes a built-in Bluetooth Smart chipset which
hasn't proved satisfactory. Bluetooth Smart for GX devices is coming soon but will not use built-
in chipsets.
5. Larger SD memory cards (SDXC) are not supported. SD cards can be used for two purposes:
1. Logging data, see this section in the ccgx manual for details.
2. Updating firmware, see this section in the ccgx manual for detials.
6. The second CANbus port is accessible via the GND, CAN-H and CAN-L terminals. Note that the
port is not Isolated. See Settings → Services for configuring that port.
7. The programmable relay can be set to act as an alarm relay, automatic genset start stop, or an
on/off switch, and is controlled via the GUI and/or ModbusTCP.
8. In the Venus GX hardware there are two relays - at present only one of them is available for use.
9. The tank level inputs are resistive and should be connected to a resistive tank sender. Victron
does not supply tank senders. The tank level ports can each be configured to work with either
European (0 - 180 Ohm); or US tank senders (240 - 30 Ohm).
10. The Venus GX has two temperature terminals which can be used to measure & monitor all kinds
of temperature-inputs. Temperature senders are not included. The required sensor is
ASS000001000 - Temperature Sensor QUA/PMP/Venus GX. (Note that this is not the same as the
BMV temperature accessory.)
11. Octo GX comes with a small Wifi antenna. You may remove and replace it with any other Wifi
antenna having an RP-SMA connector.
12. Requires the CANvu GX IO Extender and wiring kit
13. The 5V output on the Venus GX can be used to power, for example, a USB hub. Note that its
output is not current limited or otherwise protected, and it shares the internal power supply in
the Venus GX: overdrawing from it will result in shutdown(s) of the Venus GX. It is recommended
to install a fuse for prevention.
14. Though the Maxi GX, MultiPlus-II GX and EasySolar-II GX all have a dual set of RJ-45 sockets
labelled VE.Can, this port is actually a dedicated BMS-Can port. It can only be used to connected
to managed batteries like Freedomwon, BYD, Pylontech and others, at 500kbps. The hardware
does not meet the requirements for a VE.Can port; and thus it is not possible to use to port to
connect Victron products such as the SmartSolar VE.Can MPPT product range. Note that current
version of Venus OS firmware still allows to select the VE.Can function and other baudrates. The
result will be unreliable, and future firmware versions will lock the feature to BMS-Can only and
500kbps.
15. A BMS-Can port is a port dedicated to be used for connecting managed batteries, like BYD,
Pylontech, Freedomwon and others, only. It is not possible to connect Victron VE.Can products to
that port. To connect such managed battery, use our special cables, and see documentation
here. Connect the side labelled 'VE.Can' into the BMS-Can/VE.Can port on the GX Device. And
connect the other side to the battery. The baudrate of a BMS-Can port is fixed to 500kbps.
16. The GX Touch 50 connects to the Cerbo GX using a single cable; fixed permanently to the GX
Touch 50, which on the other end splits into a USB and a connector for the video signal. Both
need to be inserted into the Cerbo GX, taking one of the three USB ports. The USB part of the
cable is used to power the GX Touch 50. The cable is 2 meters in length; and can not be
extended in length.
