User manual EC Normative and Security Norms
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy, and if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can
be determined by turning the
equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
All the Arthur Holm and Albiral motorized units, has an open source AHnet protocol to external control the units using a RJ45
RS422 bus.
The ERT interface unit, is an Ethernet IP to RS422 interface, in order to use the local network to send AHnet commands to
the Arthur Holm or Albiral units. Just only opening an IP ERT port, the system can send AHnet commands by network, and the
ERT will send the commands to both of the two RS422 RJ45 buses. You can connect up to 60 units in one ERT, using the two
RS422 ports (30 units on each RS422 port)
Note: ERT-30 model has only one AHNet RS422 port. You can control up to 30 units
The ERT interface Unit and AHnet Communication Protocol have been developed to control, configure and diagnose Arthur
Holm units, such as, motorized monitors, motorized microphones, motorized cables, motorized connection box….

User manual 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 figure 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 respec-
tive user manual to configure the AHnet address on each unit and to connect the unit to the RS422 bus.
To configure 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 configure 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.

User manual AHnet adress configuration
AHnet adress configuration
There is an ERT functionality that helps the users to configure the AHnet address. To send AHnet commands to a unit, first
do you need to configure the AHnet address to individually send commands. Installing the unit (monitor, microphone or oth-
er device), do you need to configure 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 configuration. 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 configure the AHnet address on each unit. When the units receive the special AHnet address
configuration command, you hear a BEEP sound. Pressing the UP button on unit cover plate, the unit configures her new
AHnet address. The configuration is incremental. First unit that the user pres the UP button, gets AHnet address 1. Second,
AHnet address 2……..

User manual AHnet protocol
AHnet Protocol:
Using 5 bytes to communication:
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 first 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 is some AHnet commands used to control the different devices family. You will found more AHnet commands on
the particular user manual
