SYSTEM DESCRIPTION
General
ERT interfaces provide an easy and convenient system to control and
diagnose motorised monitors, microphone lifts and other automated
solutions by Arthur Holm helping to reduce the installation costs in terms
of both equipments and time.
Easy to install and set-up, they facilitate a quicker installation and
eliminate the need of external relay boxes and extra power outlets. It
is also possible to have Arthur Holm’s virtual support on site as long as
there is an Internet connection available.
AHlink wireless control is also integrated in ERT interfaces, providing an
easy and direct access to the most common settings through an app
and making the start-up and future interventions hassle free. This means
there is no need to access physically the unit to set-up or diagnose its
installation.

RF: Brigths when a mobile or tablet is connected to the unit to control
and congure the ERT using the AHlink APP.

13
SYSTEM CONFIGURATION
Use the ETHERNET unit port to connect the ERT to your local network area.
Using this port, opens the 2002 ERT IP port, and send AHnet commands
to control the devices connected to RS422 ERT ports (AHnet1 and
AHnet2). The Arthur Holm or Albiral units, has an AHnet IN and AHnet
OUT port to easily install a RS422 BUS. Next gure shows a schematic
connection diagram.
The main device controller connects to the ERT interface using the local
network area. Just opening the 2002 ERT port, the main device controller
can send AHnet commands to the ERT interface, and the ERT sends the
AHnet commands to the units by the RS422 ports.
You can connect up to 60 units to the ERT using the two RS422 RJ45 buses
(30 units on each bus). Please, follow the respective user manual to
congure the AHnet address on each unit and to connect the unit to the
RS422 bus.

14
SYSTEM CONFIGURATION
To congure the ERT IP address, do you need to download the AHlink APP.
First, do you need to activate the radio signal. Activate DIP1 on SETTINGS
device, and power the ERT unit. To control and congure the unit using
AHlink APP, download “AHLink” from App Store (IOS system) or from
Google Play (Android system). The App is free. Execute the “AHLink” on
your mobile phone.
On App options, is recommended not select “Auto Connect” and select
“Portrait” on “Orientation”. To connect to the device, selects “Scan for
local devices”

15
SYSTEM CONFIGURATION
The name always begins by
“ERT” characters and the fourth
last MAC radio address. Select
the device to control and
congure the unit.
Selecting the device, the rst

phone. This page is used to
check the device. When the
mobile APP is connected to the
unit the RF LED will bright.

AHnet ADDRESS CONFIGURATION
There is an ERT functionality that helps the users to congure the AHnet
address. To send AHnet commands to a unit, rst do you need to
congure the AHnet address to individually send commands. Installing
the unit (monitor, microphone or other device), do you need to congure
a different AHnet address on each unit. The ERT has a utility that helps
the assignation of the AHnet address task.
First of all, note that this utility it is only available on devices that has
LCD screen conguration. The devices that has AHnet address rotary
switches, don’t have this functionality.
To activate this function, activate DIP2 on SETTINGS ERT switches, and
power the unit. The ERT will periodically send a special AHnet command
to congure the AHnet address on each unit. When the units receive the
special AHnet address conguration command, you hear a BEEP sound.
Pressing the UP button on unit cover plate, the unit congures her new
AHnet address. The conguration is incremental. First unit that the user
pres the UP button, gets AHnet address 1. Second, AHnet address 2...

AHnet PROTOCOL
AHnet protocol
Uses 5 bytes communication:
BYTE 0 START BYTE
BYTE 1 ADDRESS BYTE
BYTE 2 COMMAND BYTE
BYTE 3 VALUE 1
BYTE 4 VALUE 2
BYTE 0 is the header and should always FA in HEX mode
BYTE 1 is the unit AHnet address to send the command. To send the
command to all the devices, there are special AHnet address used as
broadcast. Please, refer to the user manual unit as there are different
family broadcast addresses
BYTE 2 is the function to execute on the unit
BYTE 3 rst value of the function
BYTE 4 second value of the function. In some functions this value is
not used and should be “00”
Below, there are some AHnet commands used to control the different
family devices. You will nd more AHnet commands on the particular
user manual.
