2. PRODUCT DESCRIPTION
The DB800 is a digital radio housed in a metal casting,
whose function is to send data communication. The Data
Brick can transmit information such as position, traffic
flow, or atmospheric conditions. Three mounting holes are
provided to attach the DB800 to an indoor wall or post or to
mount inside an enclosure for outdoor use. The DB800 is
also suitable for vehicle mounting.
The DB800 operates in OpenSky Trunked Protocol (OTP)
mode and supports voice grouping, priority scanning, pre-
emptive emergency calls, late call entry, and dynamic
reconfiguration. It performs autonomous roaming for wide
area applications.
Features and user profiles for DB800 are software-defined
and can be reprogrammed over the air. This feature allows
communications protocols to be changed and added at any
time.
