7.12 RD379 PTZ SITE RECEIVER
7.12.1
Features
The RD379 is an intelligent pan/tilt/lens controller for use at a remote camera site. Its
primary function is to operate the pan/tilt unit and zoom/focus lens controls.
Features include:
•
providing simultaneous control of up to 16 site receivers per network. All data traffic
is managed by a RD315 two-wire transmitter module located in the equipment
subrack. Sites can be wired star or delta configuration and all sites are protected
against high voltage destruction with line isolation transformers on the two-wire line.
•
lens functions at two speeds.
•
views (presets).
•
approached.
•
•
to the main System Controller.
•
known as AF-232.
•
normal RS-232 asynchronous protocol is required.
•
used to the first site and then two-wire lines to the successive sites. Or perhaps two-
wire to the first site, and then fiber optic cables continuing to the successive sites.
•
direct contact or current-loop sensing alarm inputs are available. The board also
provides eight separate relay output contacts, and an iris output for control of
motorized manual iris lenses.
