Venus GX manual

Note: this manual corresponds to the latest firmware. When internet connected, the device will update to the latest version automatically. Check our blog posts for the latest firmware:

1. Comparison to the CCGX

In many ways, the Venus GX is exactly the same device as the Color Control GX. A lot of the hardware is the same. And it runs the same software, our Venus OS. Their software therefore shares the same version numbering, and new versions are released at the same time for both devices.

This section explains all the differences between the two devices, to get everyone that is familiar with the CCGX up to speed on the Venus GX as fast as possible.

  1. The maximum number of VE.Direct devices on a CCGX is 5 (2 normal and 3 via USB. Max number of VE.Direct devices on a Venus GX is 6 (2 normal, and 4 via USB).
  2. Though the CCGX has no built-in WiFi, it can easily be added by inserting a USB-WiFi dongle. See CCGX Manual, section 1.4.2 for details.
  3. The built-in WiFi in the Venus GX has (unfortunately) a very low signal strength. Making it good enough to connect to with a phone, tablet or laptop for setup and readout. 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. And make sure to run v2.06 or later on the Venus GX, the first batch of Venus GX-es is shipped with v2.05.
  4. The hardware of the Venus GX contains a Bluetooth Smart chipset, but there is no function for it in software yet.
  5. Larger SD cards are SDXC, and these are not supported. The SD cards can be used for two purposes:
  6. The second CANbus port is accessible via the GND, CAN-H and CAN-L terminals on the left of the product. This is a future function: there is no functionality behind this yet.
  7. The programmable relay can be set to act as an alarm relay, automatic genset start stop, or just an on/off switch, controlled via the GUI and/or ModbusTCP.
  8. In the Venus GX hardware there are two relays, but for now only one of them can be used.
  9. The tank level inputs are resistive: connect them to a resistive tank sender. Such tank senders are not supplied by Victron. The tank level ports can each be configured to work with either European tank senders (0 - 180 Ohm), or US (240 - 30 Ohm).
  10. The Venus GX has two temperature inputs. Which can be used to measure & monitor all kinds of temperatures. The temperature senders are not included. The required sensor is the same as used with Multis, Quattros and many other Victron products.
  11. The Venus GX has five digital IO channels. The IO is not supported yet in software. The channels are accessible via the RJ-12 socket on the side. A customer/installer needs to self-wire this. The first implemented function will probably be to count pulses from (water)pumps. Harware description: The IO inputs are non isolated. These digital inputs operate at 3V3 levels, and can withstand 5V input. Each input has an internal 10k pull-up resistor to 3V3, so it can be connected to a potential free relay or open collector/optocoupler output.

2. Accessing the device

Because the Venus GX has no display nor any buttons, this works differently than with the CCGX.

The way to access the device for setting up, as well as monitoring, is via Remote Console. Either via VRM, via the built-in WiFi Access Point, or on the local LAN/WiFi network.

2.1 Accessing Remote Console via VRM

Connect the Venus GX to the internet by plugging it into a working Ethernet network which as a DHCP server (most networks do). It will immediately connect to VRM.

Go to, follow the instructions to add the device. More information about this is in the VRM Manual.

And once done, click the Remote Console link to open the window, like this:

More information about Remote Console on VRM is explained here.

2.2 Accessing Remote Console via the built-in WiFi Access Point


  1. Make sure to be close to the Venus GX (a few meters maximum)
  2. Go to the WiFi settings on your phone / tablet / laptop.
  3. After searching, it will show up in the list:
  4. Connect to the WiFi, using the WiFi key which is printed on a label on the side of the box. The same label with that key and identifiers is also found in the plastic bag: store that somewhere safe.
  5. Once connected, navigate to

Note that, for security, it is possible to disable the WiFi Access Point. See Settings → Wi-Fi → Create access point.

Be careful: once disabled, the only way to get it back enables is by using Remote Console on VRM (requires a working internet connection) or via Remote Console on LAN (requires a working network connection, but not internet).

2.3 Finding the IP address

In case you've accidentally disabled Remote Console on VRM, the only way to re-enable that is via Remote Console on LAN. And to do that you need to find the IP address of the Venus GX. There are several ways to find that:

IP Address on VRM

On VRM, you'll find the IP address on the Device List page of the installation. Note that this does require the Venus GX to be connected to the internet.

Network (on Windows)

In a local network, for example in a home, you can also find the Venus GX in the Windows Network overview:

Double clicking the icon will open up Remote Console on LAN.

Open the properties window to see the IP address.

This uses upnp broadcast technology.

3. LED and Push button

3.1 LED

On the side of the Venus GX, there is a LED. during power-up it has different states [TBD insert states]. After a good power-up, it will always blink green.

During a forced factory re-install, a very uncommon operation, the LED has these meanings:

  • off, no image found
  • red blinking, busy
  • green on, done
  • red on, error

3.2 Small push button on the right of the long green connector

No function yet.
