GlobalLink 520

1. Introduction
Thank you for purchasing a GlobalLink 520. It allows you to connect other Victron equipment (VE.Direct), such as your Battery
Monitor (BMV); SmartShunt; Solar Charger; IP43 Charger; or Phoenix Inverter, to the Victron Remote Management (VRM) portal.
The portal is available to use free of charge, and from it you can view the status of your installation from anywhere in the world
using your desktop device or mobile phone. Here are some examples of the kind of information you will be able to view:
•Inverter demo
•MPPT Solar Charger demo
The first five years of cellular connectivity is included in the purchase price. The unit will come pre-configured and ready for use
out of the box. No need to change any settings.
Make sure you have LTE-M coverage in your country before purchasing this device: https://1nce.com/en/coverage/

• 2 pluggable terminal blocks
What's not in the box
• VE.Direct cables
2.2. Assembly instructions
1. Make note of the VRM Portal ID denoted on the sticker on the GlobalLink 520.
2. Mount the GlobalLink 520 close to the device you wish to monitor.
3. Connect VE.Direct cables between your devices and the GlobalLink 520.
4. Connect the DC Power (8V - 70V).
5. The LED will start blinking blue while it is trying to connect to the network (this could take up to 5 minutes).
6. The LED will blink green and yellow when one VE.Direct device is connected, or only green when two VE.Direct devices are
connected.
7. Visit to the VRM portal to 'add' your installation to your account using the Portal ID you wrote down in step 1. You can only
add your device to VRM once it has connected to the network (blinking yellow and/or green).

3. The status LED
LED state Meaning
Blinking blue Connecting. If the LED keeps blinking blue, check network coverage.
Blinking green Everything is OK: A connection has been made both to the LTE-M network and to two VE.Direct
devices.
Blinking green &
yellow
The device is connected to LTE-M, but only to one VE.Direct device: Check the cable &
power to the second VE.Direct device.
Blinking yellow The device is connected to LTE-M, but not to a VE.Direct device: Check the cable & power
to the VE.Direct device.
Continuous red The device detected a problem and will automatically reboot to try and rectify it.
Blinking purple The device is updating its software. This process usually takes a few minutes.

4. Cellular connectivity
The GlobalLink 520 is a cellular device which connects to LTE-M compatible 4G networks. The cellular provider of the included
SIM card is '1nce'. Their global network of operators is constantly expanding and you can check LTE-M coverage in your area
here: https://1nce.com/en/coverage/.
4.1. 4G LTE-M
LTE-M is the abbreviation for LTE Cat-M1 or Long Term Evolution (4G), category M1. This cellular technology is designed to
connect Internet of Things devices to existing 4G towers while using low energy. LTE-M does support handovers and roaming so
it is possible to use this device in a moving vehicle like a campervan (with an extrernal antenna).
4.2. Antenna
The GlobalLink 520 has an internal antenna and an SMA connector for an optional external antenna. A switch on the top of the
device determines which antenna is used. If the switch is set away from the SMA connector the internal antenna is used, when
set towards the connector the external antenna is used.
Do not set the switch to "external" if there is no external antenna connected, as this can permanently damage
your device.
The GlobalLink 520 is not rated for outdoor use. You can however connect your own outdoor antenna to the device to improve
your signal strength if the internal antenna does not have good enough reception (note: you can find the signal strength in VRM).
LTE-M uses the following frequencies: 703-803 and 2520-2620 MHz.
RSSI Signal strength Description
>= -65 dBm Excellent Strong signal with maximum data speeds
-65 dBm to -75 dBm Good Strong signal with good data speeds
-75 dBm to -85 dBm Fair Fair but useful, fast and reliable data speeds may be attained, but marginal
data with drop-outs is possibley
-85 dBm to -95 dBm Poor Performance will drop drastically
<= -100 dBm No signal Disconnection
4.3. Internal SIM card
Inside the device is a nano SIM card which is used for connectivity. This SIM is locked and can only be used in combination with
this specific GlobalLink device. It has a limited data bundle for the device to operate and receive updates over the air.

7. Data transmission to VRM
After power-up, the GlobalLink 520 will connect to the LTE-M network. Once connected, it will gather information from the
connected VE.Direct device(s), and transmit it to the VRM portal.
Every 24 hours, all available data is transmitted. In between, it will transmit the most important data every 15 minutes:
BMV Battery Monitor
• Battery Voltage
• Battery Current
• Battery Power
• State of Charge
• Alarm status & reason
SmartShunt
• Battery Voltage
• Battery Current
• Battery Power
• State of Charge
• Alarm status & reason
MPPT Solar Charger
• Solar Power
• Battery Voltage
• Battery Current
• Battery Power
• Error code
• Charge state (Off, Bulk, Absorption, Equalize, Float)
IP43 Charger

8. Digital inputs
The GlobalLink 520 comes with two digital inputs which also act as pulse counters; you can view their current state the number of
detected pulses (rising edge, 1000Hz max) in VRM.
Pinout Input
pin1 input1
pin2 input2
pin3 gnd

Page 8 Digital inputs

9. Relay switch
The GlobalLink 520 comes with one relay which can be operated from VRM from the device list page.
Pinout
pin1 NO
pin2 COM
pin3 NC
You can queue changes to the relay state in VRM. Changes will be propagated the next time the device connects and transmits
its data, and can thus take up to 15 minutes to take effect (or longer if the device has no connection).

Page 9 Relay switch

10. Input Voltage Measurement
The GlobalLink measures the voltage on its own power connector. If none of the connected VE.Direct devices is able to measure
voltage, this value is used instead in VRM.
Note that this measurement is not very accurate. At 14V it's +/- 0.2V, at 24V it's +/- 0.5V and at 48V it's +/- 1V.

11. Firmware updates
The GlobalLink automatically checks and updates it's firmware to the latest stable version. When the units starts updating the
LED will blink purple. This can take up to 10 minutes. Do not power down the unit even if the LED stops blinking for a while.
All updates are currently rolled out automatically, it is not yet possible to manually update the device.

12. Troubleshooting
Step 1: Check the device has power.
The LED on the device should be blinking in some color. If it is not blinking, check if the power cable is connected correctly and
supplies sufficient power. If you're using the included cable, be sure to also check its inline fuse which may be blown if the power
pins were accidently reversed.
Step 2: Check for cellular (LTE-M) coverage.
Verify that the LED is blinking either green or yellow. After powerup, the LED will first blink blue, indicating that it is establishing
communication with the LTE-M network and VRM. Once connected, it will start blinking green (when there is a VE.Direct device)
or yellow (when there is no VE.Direct device). In case it keeps blinking blue the unit will keep trying to establish a connection until
there is a timeout (+/- 15 min) and then automatically reboot the device.
You can check the signal strength in VRM on the advanced page where you can activate the RSSI graph. The
signal RSSI should be between -50dB (best connection) and -100dB (bad connection). Below -100dB the
connection will no longer work. You can also find the latest RSSI in the device list.
Check and make sure there is coverage in your country (https://1nce.com/en/coverage/). If there should be coverage but you
have no signal you can consider purchasing an external antenna.
Step 3: Check the connected VE.Direct devices.
Make sure the LED is blinking green or geen & yellow which indicates that only one VE.Direct device is connected. In case its
only blinking yellow, check the cable to the VE.Direct device, and power to the VE.Direct device.
Step 4: Find the device in the VRM portal
Login to VRM, and add the module by going through the "Add installation" wizard. Only after the module has made an active
connection to the cellular network it is available in VRM.
