SYSTEM DESCRIPTION
Applications
All the Arthur Holm and Albiral motorised devices provide an open
source AHnet protocol to externally control them by using a RJ45 RS422
bus.
The ERT is an Ethernet IP to RS422 interface, that allows the user to use
the local network to send AHnet commands to the Arthur Holm or Albiral
motorised devices. By opening an IP ERT port, the system can send
the AHnet commands using a local network and the ERT will send the
commands to both RS422 RJ45 buses. Up to 60 units can be conneted
in one ERT (ERT-60) by using the two RS422 ports (30 units on each RS422
port).
Note: ERT-30 model has only one AHNet RS422 port. The user can control
up to 30 units.
The ERT interface Unit and the AHnet Communication Protocol have
been developed to control, congure and diagnose Arthur Holm
devices such as motorised monitors, motorised microphone solutions,
motorised cable systems and motorised cable cubby solutions.
Box Contents
Before the installation of your ERT unit, please check the contents of the
shipping box, it must contain the following items:
• ERT unit.
• Power cord.
• Power supply 100-240Vac, 50-60Hz. Output 12V.
• User guide.
Important note: This device can only work with the power supply
included in the shipping box. This power supply can not be replaced by
any other rather than the original one.

CONTROLS AND CONNECTORS
Ethernet: RJ45 network connector. Connect the ERT to the local
network to open the 2002 port and send AHnet commands to the units
connected to the RS422 ports (AHnet1 and AHnet2).
Service: USB connector used only for rmware upgrades.
AHnet1: RJ45 RS422 port. To control the units using AHnet commands,
connect the Arthur Holm or the Albiral units on this connector.
AHnet2: RJ45 RS422 port. To control the units using AHnet commands,
connect the Arthur Holm or the Albiral units on this connector.
Note: The ERT-30 has one AHnet RS422 port connector, only. With one
ERT-30, the user is able to control up to 30 devices, and with one ERT-60,
the user is able control up to 60 devices by using the two AHnet port
connectors (30 devices connected on each port).

12
CONTROLS AND CONNECTORS
LEDs system indicators
LED1: Change the state when a AHnet command is received from the
two RS422 ports (AHnet1 or AHnet2).
LED2: Change the state when the unit receives data from the local
network port (ETHERNET).
LED3: Not used.
LED4: Change the state when the unit sends a AHnet command when
the automatic AHnet ID conguration is activated (DIP2). The ERT
interface sends commands to the units connected on AHnet1 and
AHnet2 to automatically set-up the AHnet ID on each unit.
RF: Lights up when a mobile or tablet is connected to the unit to control
and set-up the ERT by using the AHlink app.

13
SYSTEM CONFIGURATION
Use the ETHERNET unit port to connect the ERT to your local network area.
This port opens the 2002 ERT IP port and sends the AHnet commands
to control the devices connected to the RS422 ERT ports (AHnet1 and
AHnet2). The Arthur Holm or the Albiral devices have a AHnet IN and a
AHnet OUT port to easily install a RS422 BUS. The next picture shows a
schematic connection diagram:
The main device controller connects to the ERT interface by using a local
network. When opening the 2002 ERT port, the main device controller is
able to send AHnet commands to the ERT interface, and the ERT sends
AHnet commands to the units using the RS422 ports.
The user is able to connect up to 60 units to the ERT using the two RS422
RJ45 buses (30 units on each bus). Please, follow this user guide to set-up
the AHnet address on each unit and to connect the unit to the RS422
bus.
To set-up the ERT IP address, it is necessary to download the AHlink
app. First, you need to activate the radio signal. Activate DIP1 on the
SETTINGS device and turn the ERT unit on.

14
AHLINK
To control and set-up the unit
using the AHlink app, download
the AHlink from the App Store
(IOS system) or from Google
Play (Android system). The app is
free. Execute the AHlink on your
mobile phone.
On the AHlink app options, it
is recommended to not select
Auto Connect and select Portrait
on Orientation. To connect to
the device, select Scan for local
devices.
The AHlink name always begins
with ERT characters and the fourth
last MAC radio address. Select
the device to control and set-up
the unit.

AHNET ADDRESS CONFIGURATION
There is an ERT functionality that helps users set-up the AHnet address.
To send AHnet commands to a unit, the user needs to set-up the
AHnet address to individually send the commands. When installing the
unit (monitor, microphone or other device) the user should set-up a
different AHnet address on each unit. The ERT has a utility that helps the
assignation of the AHnet address task.
Please note that this utility it is only available on the devices that have
the LCD screen conguration (ISD). The devices that have AHnet
address rotary switches don’t provide this functionality.
To activate this function, activate DIP2 on SETTINGS ERT switches and
turn the unit on. The ERT will periodically send a special AHnet command
to set-up the AHnet address on each unit. When the units receive the
special AHnet address conguration command, the user will hear the
sound of a beep. By pressing the UP button on the device’s cover plate,
the unit set-ups a new AHnet address. The conguration is incremental.
The rst unit, in which the up button has been pressed, gets the AHnet
address number 1, the second one will get the AHnet address 2, and
so on.

AHNET PROTOCOL
AHnet protocol
Using 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 AHnet address unit to send the command. To send the
command to all the devices, there is a special AHnet address used as
broadcast. Please, refer to the user guide of the device, as there are
different family broadcast addresses.
BYTE 2 is the function to execute on the unit.
BYTE 3 is the rst value of the function.
BYTE 4 is the 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
families of devices. You will nd more AHnet commands on each
particular user guide.
