Hardware
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. A data cable that is connected to an energized device is live. Do not cut or terminate live data cables.
4. The cable tail can be returned to the original distribution board. Ground wire and power wire (+V) can be
connected in a loop but D+ and D– must NOT be connected in a loop. Do not connect power wire (+V) in
a loop where segmentation is required between network sections that have multiple power supplies
deployed, to ensure Network cable current limits are not exceeded.
5. Maximum allowed power supply rating and data cable current for any section of the network is the
lowest of either 2 Amps or the Cable rating per local wiring code or cable manufacturer specification.
Where required, apply power wire (+V) segmentation per network design to prevent exceeding limits. Use
only approved DyNet power supplies to ensure network reliability and safety.
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 or as per local wiring code specification (whichever is greater).
If the data cable crosses over any mains cables, it should cross at 90°, whilst maintaining correct
segregation. The wiring segregation distance may be reduced if either data cables, mains cables or both
are fitted in separate grounded metal conduits.
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), 120 Ohm, 2 W end-of-line resistors must
be installed across the D+ and D- terminals of the DyNet connector
strip on the first and last devices.
