Cables
Different types of stroke have been used in the previous examples, in order to indicate cables with different functions:
video cable:
RG 59 coaxial cable or equivalent cable
multipolar cable:
each control function of the positioning device is activated /deactivated by a relay positioned inside the receiver.
Fix the final numbers of wires according to the following directions:
7 wires for the motion of the positioning device: right, left, up, down, autopan, common, ground
6 wires for the control of polarity reversal lenses (zoom, focus, iris)
4 wires for the control of common wire lenses (zoom, focus, iris)
2 wires for the auxiliary device
3 wires for power cord
Note: We recommend the use of different multipolar cables for high tension and low tension functions.
Minimum section area recommended: 0.56 mm.² (AWG 20) for high tension wires (positioning device)
0.34 mm.² (AWG 22) for low tension wires (lens, auxiliary device)
0.75 mm.² (AWG 18) for power wires of DTMRX1
cable for the digital receiving / transmission of commands:
2 wires for to receive from the control unit (twisted telephone pair, section 0.22 mm.² AWG 24)
2 wires for the possible transmission to the next cascade-connected receiver (twisted telephone pair, section 0.22
mm.² AWG 24)
Note: Maximum distance for the connection: about 15 m in RS232; 1200 m in RS485; 1500 m in Current Loop.
If many receivers are cascade-connected, it is necessary to use two separated cables for the digital reception and
transmittion of commands (do not use multicouple cable) between the receivers
