3.2 Cables
Cable for transmission/reception of commands: unshielded twisted pair with minimum section 0.22
mm² (AWG 24):
• a pair for RS485 transmission both for KEYBOARD lines and AUX lines (max. length of connection 1200m.)
• a pair for powering the keyboards, which can be remote powered (max. length of connection 700m.)
1,5 m phone cable equipped with the keyboard
Cable for DB25 connector: multi-polar cable with minimum section 0.22 mm² (AWG 24)
Video cable: RG59 coaxial cable or equivalent
as well as being used for video transmission it can also be used for transmitting telemetry data (in this case the
max. length of the connection is 350m)
Multi-polar cable:
every pan & tilt control function is enabled/disabled by a relay inside the receiver.
• To determine the final number of wires, follow the instructions below:
• 7 wires for the pan & tilt movements (230 V~ o 24 V~): right, left, up, down autopan, common, ground (only
for 230 V~)
• 6 wires for reverse polarity lens control (zoom, focus, iris)
• 4 wires for common wire lens control (zoom, focus, iris)
• 7 wires for preset management: 5 connected to reference potentiometers, +5 V
• 4 wires for the Wiper
• 3 wires for the Washer
• 2 wires for each auxiliary used
• 3 wires for power supply cable
Note: we recommend using different multi-polar cables for low and high voltage functions.
Recommended minimum section:
PC cable: 9 poles- standard serial extension cable (max 15m)
0.56 mm² (AWG 20) for high voltage wires (pan & tilt, wiper, washer)
0.34 mm² (AWG 22) for low voltage wires (lenses, auxiliaries, preset)
0.75 mm² (AWG 18) for power supply wires the receiver
