Features

Built-in GPS receiver

• The GX LTE 4G includes a built-in GPS receiver. When the optional active GPS antenna is installed, the system can be tracked as well as geo-fenced on the VRM Portal.
• The required accessory part number is GSM900200100 – Active GPS Antenna for GX GSM.

GX compatibility

• The GX LTE 4G can be used with any of the GX devices and requires Venus OS v2.60 or newer to be installed on the GX device.

SIM card

• It requires a SIM card in the Mini-SIM format.

When to use a mobile router instead

• The GX LTE 4G provides only an internet connection for the GX device. Sharing the internet with laptops, phones, or other devices is not possible.
• For installations where more devices require internet, as is often the case on a yacht or RV, or where a reliable failover/backup solution is needed, consider installing a mobile router with this functionality instead.
• A mobile router can share cellular data with multiple devices such as smartphones, tablets, laptops, and other devices via its Ethernet port or WiFi and can switch to a previously configured WiFi connection in the event of an Ethernet connection failure or vice versa.

Antennas and accessories

• A small indoor LTE antenna is included. Optionally, we also sell an outdoor LTE antenna, which increases the range:
• Part number GSM900100400 – Outdoor 4G GSM Antenna

What’s in the box?

• GX LTE 4G (with integrated USB cable)
• GSM 2G/3G/4G mini rod antenna (for indoor use)
• DC power cable (with inline fuse and terminal block)

Installation and configuration

Installation step-by-step

Follow the steps below to install the GX LTE 4G:

1. Mount the device in a place that is not covered by metal objects. Consider using the optional outdoor antenna when installing the GX LTE 4G in a closed metal enclosure, car, or van to increase the range.
2. Mount the included antenna to the SMA connector labeled LTE.
3. An optional active GPS antenna is screwed onto the SMA connector labeled GPS.
4. Insert the SIM card. You will need to eject the SIM card tray with a pen or other pointy object. Be aware that the SIM card tray sits slightly recessed inside the unit. Be sure to push it in.
5. Connect the GX LTE 4G to the GX device with the supplied USB cable. Use a USB hub if all USB sockets are already in use.
6. Connect the DC power supply (8 to 70 VDC). A 1.4 m cable with M10 cable lugs and a built-in Slow Blow fuse 3.15A 250V, 5x20mm is included. Pay attention to the correct polarity as labeled on the front sticker.
7. After power-up, the blue LED will be solid blue. Once it has registered on a network, the LED will start blinking slowly. Finally, when the internet connection is established, the LED will blink quickly.

• The ground of the GX LTE 4G power supply must match that of the GX device.vic
• This is usually battery minus if the devices are supplied via the battery.

Configuration

• The GX LTE 4G is configured entirely via the connected GX device.
• Setting a SIM PIN helps reduce the risk of the SIM card being stolen and used.

Use a mobile phone to set the SIM-PIN, and thereafter configure it on the GX device as follows:

1. When using a SIM card with its SIM-PIN security disabled, the system will work without further configuration.
2. Setting a SIM PIN helps reduce the risk of the SIM card being stolen and used. Use a mobile phone to set the SIM-PIN, and then after configuring it on the GX device as follows: Go to Settings → GSM modem → PIN.
3. Enter the same PIN that was previously set in the mobile phone or provided by the network operator.
4. Go to Settings → GSM Modem → APN and set the APN name if necessary. Some mobile networks require manual configuration of an APN especially when roaming. Contact your network operator for details.
5. If you are installing the GX 4G LTE in an area where you can expect internet coverage to be occasionally disrupted, you should enable the “Reboot device when no contact” option in the GX device’s VRM menu. This will automatically restart the GX device and power cycle the GX if it has failed to transmit data to VRM for the configured time.

• Note that if you are leaving internet service coverage areas (such as an RV on the move, or a boat leaving the dock to go to sea), then it is recommended to disable this setting so that your GX is not rebooting itself for no reason.
• Or set it, for example, to a two-hour time-out and accept a reboot every two hours when underway.
• Watch this video to learn how to connect via LAN, WiFi, and the GX GSM which is the same as the GX LTE: Connecting a Victron GX Device online and setting up a GX GSM

Operation

SIM status

The SIM status is displayed on the GSM overview page on the GX device. The following table shows all possible states and their meaning:

tray might hang out a little.
PIN required| SIM card requires a 4-digit PIN for unlock.
PUK required| SIM is locked due to wrong PIN inputs. 8 digit PUK is required to release the lock state.
SIM failure| SIM does not respond – might be broken.
SIM busy| SIM is in a busy state.
SIM wrong| The type of SIM is not supported.

Status Bar

Cellular modem status can be checked at a glance by looking at the status bar .

GPS

When the optional active GPS antenna is added, the position is sent to the VRM portal and also displayed in the GX device as follows:

Troubleshooting

Troubleshooting guide

• There are many reasons for a modem internet connection not working.
• Carefully go through each step of this troubleshooting guide.
• Make sure to start at the first step.
• When asking for help, make sure to mention each step taken and the result.

Settings → GSM modem menu.
3| SIM card status| Check the SIM Status in the menu; it must show “Ready”. It will show “SIM not inserted”, “PIN required”, or “PUK required”, and more related errors when there is a problem. Please refer to the SIM status list [6] for details.
4| Signal strength| One bar is the minimum for VRM logging; 2 or 3 bars are necessary for a working remote console. An outdoor antenna typically increases the received signal by 15 to 25 dB.
5| Carrier Registration| Check that the name of a Cellular provider is visible in the “Carrier” field. If it is not, check signal strength and otherwise contact your SIM card provider and/or insert the SIM card into a phone to double-check its operation and subscription status.
6| Internet connection| Verify that the Internet shows “Online”. Reasons for the system to not go “Online” whilst properly registered on the Network are:

1)  APN not configured, contact the network operator for details.

2)  The network is a different one than the home network (ie. roaming), and the setting to permit Roaming is disabled.

3)  Signal strength is strong enough to register on the network but not to open the data connection to the internet.

7| Connection to VRM portal| Verify that the VRM Portal menu shows a recent last connection time. See Settings → VRM Portal. For more details, see the VRM Connection troubleshooting chapter of the GX Manual.

• Note that Ethernet and WiFi connections have priority over the cellular connection.
• Even when the available Ethernet or WiFi connection does not have a good connection to the internet, there is no automatic detection in place which in such cases switches over to the GX GSM.
• In more technical language : when the cellular data connection is active, it is configured with a high routing metric.
• This way, the Linux kernel prioritizes Ethernet or Wifi when these are available.

What to do if the GX LTE 4G is not staying connected?

• Enable the “Reboot device when no contact” configuration setting in the VRM menu of the GX device.
• That will reboot the GX (and with it the GX GSM) automatically if the internet connection is not available. See also the configuration chapter [4] for more details.

Appendix

Accessory / Antennas

Outdoor 2G and 3G GSM Antenna

This antenna can be used with the GX LTE 4G, for 2G, 3G as well as 4G bands.

Outdoor 4G GSM Antenna

• This antenna is optimised for 4G frequency bands and as such will have slightly better reception on the 4G network. It can be used with the GX LTE 4G for 2G, 3G, and 4G bands.
• If the 2G/3G variant does not provide sufficient signal quality in an installation, the solution is to contact a local GSM antenna provider.
• All the necessary information, including a link to the cellular modem (Simcom) used, can be found in this manual.

Active GPS Antenna

Notes regarding regional coverage

A good reference to check frequencies is the 4G world Coverage Map. Note that the page also contains 2G and 3G information, which is on its GSM World Coverage link at the top.
