Introduction

Overview

I/O Modules are such a key component in any building automation system, that we wanted to see how we

can perfect every aspect of its operation looking at the hardware, software, and overall usability.

Together with Carel, an Italian controls manufacturer trusted all over the world in critical control

applications for more than 40 years, we have created Link IO - ascalable and fully integrated BMS product

that will last you for many years to come! Now available World-Wide.

Wiring the RS485 networks

Some useful links to our knowledge base website:

How to wire an RS485 network https://know.innon.com/howtowire-non-optoisolated

How to terminate and bias an RS485 network https://know.innon.com/bias-termination-rs485-network

Note: the RS485 ports are not opto-isolated. Carefully check the orientation of the G and G0 terminals on all

devices to be the same and the shield to be connected correctly to avoid damaging the units.

Setting the expansion

The expansion (part number LNK-IO16-EXP) setup is done using the dipswitches on the top side, near the

RS485 connector (J6 BMS). Remember to power cycle the device when the setting is changed.

The dipswitches corresponding to “Ext”, “Baud” and “Prot” must be configured to a fixed position.

The dip-switched are numbered in the front from 1 to 4 and the position is as follow:

Prot

Baud Ext

The “Address” dipswitches will need to be configured according to the expansion number, from “1” to”10”.

Expansion addresses will be always consecutive, so if you have 2 expansions, you will use addresses “1” and

“2”, if you have 3 expansions you will use addresses “1”, “2” and “3” and so on

Address 4 dip-switches configuration is shown for all 10 expansions as follow:

Address 1

Address 2

Address 3

Address 4

Address 5

Address 6

Address 7

Address 8

Address 9

Address 10

Example of configuration for expansion 1, view from the top-down:

Display navigation

Display and keys

The display in Link IO is a graphical B/W display with backlight with 132x64 pixels.

All the settings are accessible using the display and the navigation keys

Cursor on top-left of the screen or no cursor: go to previous page.

Cursor on top of setting: increase value.

Within a menu: scroll menu up.

Move cursor to next position and confirm setting.

Within a menu: enter menu selection.

Cursor on top-left of the screen or no cursor: go to next page.

Cursor on top of setting: decrease value.

Within a menu: scroll menu down.

Cursor on top-left of the screen or no cursor: go back one menu level.

Cursor on top of setting: send cursor to the top-left of the screen.

If on “warnings and alarms”, return to the last page visited.

Go to the main settings menu.

Go to “configuration warnings and alarms” screens

Settings are password protected and users will have to login to view and edit. The password screen is

displayed when trying to enter any configuration menu to allow the user to login (see in the next chapter

how). “I/O readings” is the only part always accessible without logging in.

Settings of all expansions are configured from the main device. The expansions will not work in isolation.

The display backlight is automatically turned OFF if no button is pressed for more than 5 minutes. This

function makes sure also that the user is automatically logged out and the screen goes back to the main Link

IO page.

The menu button has an independent backlight. If ON, it indicates the user is currently logged in.

The button has independent red backlight. If ON, it indicates there is a problem that needs to be fixed,

such as a configured expansion being offline or a wrong configuration on the Universal Channels.
