Sunhillo's Surveillance Gateway Unit (SGU) is a robust, versatile and
modular platform designed for surveillance sensor data formatting
and protocol conversions. The SGU is scalable, providing the capability
to add modules and capabilities as mission requirements dictate. The
SGU is the ideal solution for networks requiring high-density system
interfacing to multiple serial ports with the ability to scale to future
network demands.

The SGU's flexible platform enables synchronous, asynchronous,
Bi-sync plus HDLC serial/LAN interconnectivity and can be
programmed to perform essentially any data format
conversion. Generally, the modules are pre-configured
to your specifications at the factory. Common
conversions performed by the SGU include
message format transformations between
surveillance data in CD-2, ASR, various
ASTERIX categories (e.g. CAT 01, 02,
33, 34, 48, and others) in addition
to sync serial and LAN formats.

The SGU main chassis assembly is a 19" EIA standard rack mount unit
with an elevation of 4U and can be provisioned with up to 32-serial ports.

The basic building block of the SGU is the Active Receptor assembly.
Each Active Receptor assembly serves as the interface to 8-serial ports
of data. Standard serial cables connect directly to the rear of each SGU-AR
maintaining independent high speed connectivity. Dual power feed
inputs are provided from the redundant power supply configuration.
The SGU-AR provides IP-based network connectivity via dual ethernet
ports located on the front panel.
