Dome connection cable [REQUIRED]
The supplied Dome connection cable is 10 m long, and is fitted at both ends with a
standard RJ45 connector. The Dome end should be connected using the supplied
weatherproof connector, the XTU end should be connected to the RJ45 connector.
A special split rubber M20 cable gland for use on the XTU end of the Dome
connection cable is supplied, this allows a weatherproof seal to be made on the
cable without having to pass the RJ45 connector through the sealing rubber. See
Section 9.5: Wiring guide.
Twisted pair from controller [OPTIONAL]
D-type (RS485) telemetry should be connected to this terminal, the cable type
should be a suitable twisted-pair cable 100-120 Ohms designed for high-speed
communication purposes, e.g. Belden 8205.
The two extremities of the RS485 network should be terminated. Generally this will
be the last Dome and the control equipment. LNK1 on the XTU will perform
termination and should be either 'made' which is terminated or 'open' which is un-
terminated.
Alarm contacts [OPTIONAL]
Connection to these alarm inputs must be from volt free contacts, connect from
ALM1 to COM, ALM2 to COM, ..., ALM7 to COM as shown in the XTU connection
diagram. Example use - point the Dome camera module to a chosen preset when a
PIR device is triggered.
Relay outputs [OPTIONAL]
Use the outputs COM to N/O and/or N/C to control an auxiliary device, such as an
alarm system.
Warning: 1.5 A, 24 V DC max.
2-core telemetry cable from Photon controller [OPTIONAL]
Connect to this terminal if Photon telemetry is to be used (not polarised).
