Connecting the Boxer controller to intercom systems

When connecting the Boxer controller to intercom systems, you should be guided by the diagram presented below (For analog intercoms)
Power supply to the device
The device has two power supply inputs
Version 1.3.1


1. To use with Domovoy RS485 modules, you must connect the V1 POWER 9-12V input to a 9 Volt power supply. The use of power supplies for other voltages is PROHIBITED, as the modules may fail due to high voltage.
2. To control the power supply, the V1 POWER 9-12V input is connected to the 9...12 Volt Power Supply, and the +V2 UPS (battery) input is connected to the battery. If you need to control the power supply and simultaneously use it with Domovoy RS485 modules, you must use a 9 Volt power supply at the V1 POWER 9-12V input.
Version 2.1 and higher
1. In this version, for connecting Domovoy RS485 modules there is a separate output with +5V power supply (6.3V for the Boxer v.3.4 + version). In addition, this output is equipped with protection. If the specified current is exceeded (for example, a short circuit of the power wires on the module), the protection will operate and the power will be turned off, which will be indicated by the message MODSHORTCIRCUIT. Every few seconds, the Boxer will attempt to reapply power.
2. Power supply to the Boxer can be supplied through the V1/V2 terminal blocks, as well as through the LAN connector. Plus of the power supply is for blue (4th contact) and blue-white (5th contact). Minus of the power supply is for brown-white (7th contact) and brown (8th contact). Supply voltage is from 9 to 48 V. That is, it can be powered via a standard passive POE power supply. Please note that Boxer does not know how to request voltage via POE itself, so it cannot be powered from the port of the POE switch.
3. Input V2 can be used to monitor batteries up to 48V
All modules can be powered from a separate power supply, or from a special Boxer output. When designing a power supply system for modules from a special Boxer output, it is necessary to take into account the voltage decreasing the conductors.

Domovoy RS485 v1.2
They require a supply voltage of no lower than 4.5V and no more than 9V, therefore they work with any version of Boxer or with a separate power supply 5...9V

Domovoy RS485 v1. 5
Require a supply voltage of no lower than 5.5V and no more than 8V, so they work only with the Boxer v.3.4 + version or with a separate 7.5V

Barrier.
They require a supply voltage of no lower than 4.8V and no more than 9V, so they work with any version of Boxer or with a separate power supply 5...9V.

IMPORTANT!
If the line is long, due to voltage sag, the modules may receive a voltage lower than the operating voltage. In this case, it is necessary to turn off the power supply to the module from Boxer and use a separate 7.5 V power supply to power the module. Power supply of the modules v1.5, in the range of 5.5...8 Volts, so you need to use Boxer v3.4+, or install a separate 7.5V power supply directly on the module.

If it is necessary to connect the Boxer controller to digital intercom systems, you should use the Domovoy RS485 digital module (labeled V1.2.1), the connection should be made according to the following diagram

Connection diagram of the Domovoy RS485 V1.5 module to digital intercom systems

To connect the Domovoy RS485 module version 1.5 to digital intercoms, you must turn on the “Digital” switch and connect it according to the connection diagram to digital intercoms. To connect to an analog coordinate intercom, you need to turn off the “Digital” switch

Connection diagram of Domovoy RS485 digital modules to the Boxer controller, in case of using several modules

The operating mode of the system is Master - Slave, that is, all slaves (modules) execute the commands of the master (boxer). Each module must have an address. If modules with the same addresses are connected to Boxer, the system will not work. All addresses must be unique within the same RS485 line.
If possible, use the module address equal to the entrance address.
There is a memo on the module with the rules for addressing modules.

In Domovoy RS485 v1.2 modules, the fourth switch labeled 5V LOGIC must be turned on when connecting intercoms with five-volt logic (Eltis, Metakom). In Domovoy RS485 v1.5 modules, you can turn on the 120 Ohm matching resistance via the RS485 bus with a switch, and turn on the module for working with digital intercoms.
