3.
Mount the XTU in the selected position and orientation using appropriate
fasteners for the mounting substrate. See Section 9.2.2: Mounting the XTU.
4.
Set the RS485 termination resistor if required.
5.
Route and connect all of the required cabling to the XTU (use the supplied
special M20 split rubber cable gland for the Dome connection cable)
6.
Power up the XTU.
7.
Orientate the LCD display to suit the mounted position.
8.
Set-up the XTU to operate correctly with your chosen controller, set the
protocol (e.g. MOLYNX V3), set the interface (e.g. RS485 or Coax control),
set the receiver address (e.g. camera '1'). See Section 12: Telemetry
controller operation and setup.
9.
Optional video test. Press the
view of what the Dome camera is pointing at.
Press the
key to resume normal operation.
10. After the XTU has been fully set-up fit the lid on the XTU securely using the 4
lid mounting screws to ensure a weatherproof seal.
The XTU should be located in a position which allows the most suitable and
convenient routing and connection of the required cabling. Factors to consider are
the proximity to the Dome unit (10 m cable supplied as standard, extendable to
30 m maximum), power supply, connections to telemetry controller, alarms and the
security/protection of the chosen location. The XTU is fitted with a tamper switch
that is activated upon opening of the enclosure, but the enclosure itself is not
tamper-proof.
If a cable longer than 10 m is required, it can be increased to 30 m maximum,
using Cat-5e UTP 4 pair 24 AWG type cable. Ensure the correct coloured wires are
wired to the correct pins (see Section 9.5: Wiring guide).
Once a suitable location has been found, mark the positions of the four mounting
holes at 235 mm x 160 mm. The mounting holes in the enclosure have a diameter
of 4.5 mm, so select fasteners to suit this and drill holes to match the chosen
fasteners and mounting substrate. The head of the fasteners used should not
exceed 9 mm in diameter.
To ensure that the unit is weatherproof (IP67) the cable glands must point
IMPORTANT
downwards.
Remove the required gland knockouts by punching through the plastic around the
edge of the knockouts using a small screwdriver. Knockouts are available in the
enclosure for the following metric cable glands:
7 x M12/M20
–
2 x M16/M25
–
Offer the enclosure up to the mounting holes and fix in place with the chosen
fasteners.
