Connection scheme for the sequential switcher in double configuration
In order to control two SW82REM sequential switchers from a DCMT8 keyboard, as described in the following
paragraph, it is necessary to connect them according to this scheme:
Cables
In the above schemes, different lines have been used to show different types of functions:
video cable:
coaxial RG 59 or equivalent cable.
For longer distances it is advisable to use a video transmission system via twisted pair cable.
multipolar cable:
each pan & tilt function is enabled / desabled by a relay inside the receiver.
Define the number of wires in the multipolar cable:
•
7 wires for pan & tilt movement (230 V~ or 24 V~): right, left, high, low, autopan, common, ground (only 230 V~)
•
6 control wires for reverse polarity zoom lenses (zoom wide, zoom tele, focus near, focus far, iris open, iris close)
•
4 control wires for common ground zoom lenses (zoom, focus, iris, common)
•
2 reference wires for preset handling, and 1 additional wire for each preset function.
For each auxiliary function, wiper and wash, provide for a couple of wires.
For further information, refer to DTRX instruction manual.
cable for control digital transmission:
Two couples of twisted pair cable, minimum diameter 0,6 mm ( section 0,22 mm.² AWG 24):
a couple Transmission / Earth + a couple Reception / Earth.
The maximum connection distance is about 15 m in RS232; 1500 m in Current Loop towards the telemetry. The maximum connection distance
between the keyboard and the switchers SW42REM/SW82REM is about 500m in Current Loop.
The telephone cable supplied is 1,5 m long: for longer distances, use RJ connector blocks.
