Introduction
A Digital Camera Station forms the receiver end of a digital remote control system. A digital
remote control system is used to control camera functions such as pan, tilt, zoom, focus and
iris, light on/off and open/close gates etc..
A digital remote control system has the advantage of long transmission distance and low cable
installation cost due to the fact that a standard 2 x 0.6 mm twisted pair cable may be used for
the control of up to 12 functions.
The Digital Camera Stations BDR-510/2 and BDR-514/2 is designed with special attention to
transmission safety and stability.
The BDR-510/2 and BDR-514/2 camera stations are addressable which means that up to 64
units can be controlled via one twisted pair line.
The BDR-510/2 and BDR-514/2 are delivered as self-contained units with a mains change-over
switch for selection between 230 VAC and 115 VAC mains voltage.
The BDR-510/2 and BDR-514/2 is housed in an IP65 rated ABS-box and can be used in
connection with SYSTEM 500M and SYSTEM 1000M. Besides the BDR-510/2 and BDR-514/2
can be controlled and programmed directly from the keyboards 1500M, 1501M, 1502M and
1503M.
1.1
ERNA Format:
The BDR-510/2 and BDR-514/2 are controlled via the ERNA protocol (Ernitec Asynchronious
Serial One-way Camera Control).
With this camera control protocol it is possible to use standard modems between a system and
a camera station (or between two BDR-5XX) if the distance is more than 1200 meter.
The new ERNA protocol can be generated from a PC, which means that camera control can be
made via the PC's RS-232-C port.
The format of this protocol is as follows (Version 2.0, Release 961016):
