3.2.1 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.)
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)
3.3 Switching on and off
Before connecting to the power supply:
• Make sure the supplied material corresponds to the required specifications by examining the identification
plates as described in section 1.5 Identification Data
• Make sure the matrix and other components of the system are closed properly so that there is no possibility
of direct contact with live parts
• The matrix and other devices in the system should rest on a large, solid base.
• The power supply cables should not get in the way of the installer technician when he is carrying out normal
operations
• Make sure the power outlet and extension cables, if used, are sufficient for the system power consumption.
SWITCHING ON: insert the power supply plug in the power outlet and connect the corresponding jack
to the matrix connector labelled 12VDC. The front side led must be lighted.
SWITCHING OFF: remove the external power supply plug from the power outlet and disconnect the
jack from the matrix.
