o Interface LVUART (UART with TTL/CMOS-consistent signal levels).

• Backup drive controller;

• Indication mechanisms;

• Headset adapter circuit.

External interface:

• 4 lines of digital current inputs;

• 4 lines of powerful control switches (for the current up to 1А), which can

commutate the load both for “+” of the energy supply and for the common wire.

The switches configuration depends upon the modification of the item. Such

version can be supplied:

o 4 switches for “+”;

o 4 switches for the “common” wire;

o 2 switches for “+”, 2 switches for the “common” wire.

• 2 analog voltage measuring inputs (ADC0,ADC1). The range of the measured

voltages (-250mV)-(+24250mВ), accuracy +/- 100mV;

• Bus-line I2C master. (for connection of several I2C Slave devices to the

Terminal);

• Input for connection of the DC energy supply 9-30V.

Attention!

The metallic housing of the device is connected to the common wire of the control assembly.

The common wire of the coaxial antenna connector is also connected to the housing. The

energy supply and interface circuits are connected to the galvanically isolated common wire of

the discontinuous terminal connector. Power supply can be fed only relating to the terminals

“-“. If the common wire of the energy supply turns to be connected with the Terminal

housing, the system will save its operability, but all the advantages of the galvanic isolation

will fail.
