Installing the Data Network
A
Do NOT connect DALI or mains power to DyNet data terminals.
1.
The data cable is connected to all devices as per the project
schematic following correct color code and DyNet terminations.
Devices may be wired in any order.
2.
The recommended connection method is to ‘daisy chain’ devices in sequence, starting at the first device,
then looping in and out of each device, with a single cable terminating at the last device. There should
not be any branching, and only the first and last device should terminate a single cable, all other devices
should terminate two cables.
3.
The cable tail can be returned to the original distribution board. Ground and Power can be connected in a
loop but D+ and D– must NOT be connected in a loop.
4.
A data cable that is connected to an energized device is live. Do not cut or terminate live data cables.
5.
Maximum data cable current = 2 Amps.
6.
The data cable should be segregated from mains cables by a minimum of 50 mm (2 in) for shielded cable
and 300 mm (12 in) for unshielded cable. If the data cable crosses over any mains cables, it should cross
at 90°.
7.
On Button Panels and Sensors, the Shield wires must be terminated into the shield terminal. Shield wires
are automatically earthed on each controller. For controllers that do not have a shield terminal, the shield
should be twisted together and taped to the cable sheath to maintain continuity.
8.
The maximum recommended length for DyNet cables between two network bridges is 800 m (2620 ft).
For cable runs over 300 m (1000 ft), (or baud rates over 9600 bps) a 120
Ω
end-of-line resistor must be
installed across the D+ and D- terminals of the DyNet connector strip on the first and last device.
