GX GSM manual
1. Introduction
The GX GSM is an accessory for GX-devices. It is a cellular modem; providing a mobile internet for the
system and connection to Victron Remote Management (VRM).
It requires a SIM card of the Mini-SIM format; and connects to the GX-device with a (supplied) 1m USB
cable.

purchase the GPS Antenna.
GSM900200100 - Active GPS Antenna for GX GSM
See bottom of this manual for photos and specs of both optional antennas.
Compatibility
The GX GSM can be used with any of the GX Devices.
The GX GSM requires Venus OS v2.22 or newer to be installed on the GX Device.
When to use a mobile router instead
The GX GSM only provides an internet connection for the GX-device: there is no option to share the
internet to laptops, phones, or other devices.
For installations where more devices need internet, such as a yacht or RV, consider installing a mobile
router instead. More information here.
2. Installation
Mount the device and connect the antenna. Consider using the outdoor antenna when installing the
GX GSM in a closed metal enclosure.
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 all the way in.
Connect the GX GSM to the GX-device with the supplied USB cable. Use a USB hub if all USB sockets
are already in use.
Connect DC power supply (8 to 70 VDC). A 1.4M wire is included, with M10 lugs and an inline fuse.
After power-up, the blue LED will be solid blue. Next, once it has registered on a network, it will start
blinking slowly. Finally, when it has established the internet connection, it will be blinking fast.
3. Configuration

Victron Energy - https://www.victronenergy.com/live/
When using a SIM card with its SIM-pin security disabled, the system will work without further
configuration.
Setting a SIM pin helps reducing the risk of the SIM card being stolen and used. Use a mobile phone to
set the SIM pin, and there after configure it on the GX-device.
Settings → GSM modem → PIN code
Some mobile networks require manual configuration of an APN specially when roaming. Contact your
operator.
APN name can be configured in Settings → GSM Modem → APN.

Either on purpose, because an ethernet or WiFi connection is available.
GSM modem is properly configured, the 3G/E/etc icon reflects that the GSM modem internet
connection is in use.
WiFi is available and its internet connection is in use. WiFi has priority over GSM.
SIM PIN code is required.
Roaming, only informative. To use internet connection while roaming it needs to be enabled
in
Settings → GSM modem → Allow roaming.

6. Trouble shooting
There are many reasons for modem internet connection to not work. Carefully go through each step
of this trouble shooting guide. Make sure to start at the first step. When asking for help, make sure to
mention each step taken and the result.
Step Details
1 Power Check that the blue LED is either lit continuous or blinking
2 USB connection The modem must be connected to USB, and visible in the Settings → GSM
modem menu
3 Simcard status
Check the SIM Status in the menu, it must show “Ready”. It will show “SIM not
inserted”, or “PIN required”, or “PUK required” and more related errors when
there is a problem. Please refer to the SIM Status list for details.
4 Signal strength 1 bar minimum for VRM logging, 2 or 3 bars are necessary for a working remote
console
5 Carrier registration
Check that a name of a Cellular provider is visible in the “Carrier” field. If it is
not, check signal strength and otherwise contact your simcard provider and/or
insert the simcard in a phone to double check its operation and subscription
status.

Step Details
6Internet
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.
7Connection 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.
An outdoor antenna typically increases received signal by 15 dB to 25 dB.
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 case 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 prioritises Ethernet or Wifi when these are available.
This screenshot shows how all details look when everything is OK:
7. Supported Frequencies (2G/3G)
GX GSM, part number GSM100100100:
2G (GSM/GPRS/EDGE): 850/900/1800/1900 MHz (Quad-Band)
3G (UMTS/HSPA+): 900/2100 MHz (Dual-Band)
The used module is a Simcom SIM5360E.
A second model is coming, expected in 2020 Q3, having below frequencies, suitable for the common
networks in Mexico, USA & Canada as well as various countries in Southern America.
2020-01-18 23:28 7/8 GX GSM manual
Victron Energy - https://www.victronenergy.com/live/
2G (GSM/GPRS/EDGE): 850/900/1800/1900 MHz (Quad-Band) - same between both models.
3G (UMTS/HSPA+): 850/1900 MHz (Dual-Band)
This new product will be based on the Simcom SIM5360A.
Regional Coverage Information
USA, Mexico, Canada and most of South America: 1900 MHz is the most common frequency for 3G,
which is unsupported for the current version of GX GSM. But a second model is coming in 2020, see
above.
Australia: The 900MHz 3G frequency in remote areas is typically provided by Optus. Telstra's rural 3G
network operates at 850MHz which is not supported with the current version of GX GSM. Both Telstra
and Optus operate 2100Mhz networks in urban areas, and are supported.
In case of uncertainty please double-check: GSM World Coverage Map
