UHF Transceiver
The system comprises a GDT unit (IGDT-TR-UHF-XXX) and up to ten ADT units (IADT-TR-UHF-XXX). The GDT is capable of interfacing with a single ADT or up to ten ADTs simultaneously. The system is fully configurable to operate within any frequency in the XXX–YYY MHz UHF range, with frequency adjustments available to meet client-specific requirements.
The system employs a time-slot architecture consisting of 60 time slots, each 16.4 ms in duration, within a 0.984-second cycle. During each time slot, the GDT transmits a packet if payload data is available. If an ADT is assigned to the time slot and has payload data, it transmits immediately after the GDT.
All transmitted packets are secured using Twofish 256-bit encryption and incorporate Turbo Code 1/2 error correction for enhanced reliability. Notably, time-slot synchronization is achieved independently of GPS, ensuring robust and flexible operation.

GDT
- Controlled through an Ethernet 10/100 interface.
- Can be sent settings messages and payload messages.
- Sends status reports and any payload received from the ADT.
ADT
- Controlled through a RS-422 interface
- The ADT can be sent settings messages and payload messages.
- Sends status reports and any payload received from the GDT
Note : the system is based on software controlled transmitters and receivers.
Accordingly operation parameters can be changed according to customer needs
(payload size, timeslot length, control interfaces, bit rate,ICD)
