But it is also a useful feature when Link IO is enclosed within a panel: the external display can be panel mounted and be accessible from outside of the panel door, providing all the useful I/O live readings and all the capabilities of the on-board display. -
Page 16: How To Connect The External Display To The Main Link Io Unit
How to connect the external display to the main Link IO unit The Link IO external display comes with an RJ12 6 pin connector on the back. You will need to provide a cable to connect the RJ12 to the J3 Display port on Link IO, following the schematics below. -
Page 17: I/O Readings
If a function is enabled and using an output, the function will bypass any command from the BMS (and BMS watchdog) and the Link IO main unit will be in full control of the output autonomously. icon will be shown next to such output to know it is being controlled by a function •... -

Page 21: Auto/Manual
On the main unit 2 extra Analog Outputs are available to be configured in either AUTO (controlled by BMS, watchdog or functions) or in MANUAL mode, where a fixed value is set. In the example below, Analog Output 2 is fixed to a manual position of 7.5V (75%) Document name: Link IO - Manual Document date: 1.2 10/02/2020... -

In a DIRECT control operation, the output will be triggered ON when the analog input value is equal or above set-point + hysteresis. It would be then maintained ON until the analog input value goes below set-point. Document name: Link IO - Manual Document date: 1.2 10/02/2020... - Page 26 - hysteresis.

All Universal Channels configured to read “passive analog inputs” (any NTC, PT1000, PT500, PT100, PTC) will display a temperature, and by default they are shown in ˚C (Celsius). It is possible to convert the temperatures to ˚F (Fahrenheit) within the Link IO module, so no conversion is required on the BMS. -
Page 31: Buzzer "Beeping" Mode
If you plan on using ambient tracking, a solution would be to filter the required set-point changes within the BMS and send them to Link IO only every 15 minutes for example. Buzzer “beeping” mode By default, the on-board buzzer gives a feedback “beeping”... -

USB. Saves the file on the root directory of a connected USB memory stick (USB 2.0 max). This operation is very useful as the same file can be used on other Link IO main devices and restore (RESTORE DATA) all the settings contained in the txt file within the Link IO, effectively reducing massively configuration time for extended repeatable configurations. -
Page 33: Restore Factory Defaults
Restore factory defaults From the general settings menu it is possible to restore the Link IO device to the factory settings, by changing the setting from “NO” to “YES” and press Enter There are special cases where the device might not be accessible (“setting log in password” lost is probably the main example). - Page 34 Gateway 192.168.80.1 0.0.0.0 Expansions Number of expansions Temperature readings Celsius of Fahrenheit CELSIUS General settings Pulse counter function Flash saving frequency Every 15min Display user access password change Password 1234 Document name: Link IO - Manual Document date: 1.2 10/02/2020...

Link IO power supply type can be showing “AC” (alternating current), “DC” (direct current), “PSU” (when a dedicated super capacitor module is connected and the mains power supply is missing) or “N.A.” (when there is a problem with the voltage reading internal module). -
Page 36: The Web Configurator
Examples of file name: EXPORT_0.txt, EXPORT_5.txt, EXPORT_67.txt Note2: the file saved from the configuration tool is compatible with both the IP and RS version of Link IO. Settings that are not applicable for the destination unit will be simply disregarded. -
Page 37: Web Tool Sections - General
This configuration section starts with common settings applicable to both the IP and RS version of Link IO You will be presented then with specific settings for the RS and IP version of Link IO. Configure them both if you want to use the same file for both type of devices: the file will be compatible Note: you will notice that the only missing configuration is the ethernet port IP, subnet, DNS. -

Page 43: Using A Usb Memory Stick
On the USB memory stick, we need to create a folder called “UPGRADE” and place the “Autorun.ap1” file within that folder With the USB stick ready, we are going to plug it to the USB port of Link IO. Once the USB memory stick has been recognised, the screen will automatically prompt for confirming the upgrade. -
