DyNet Cable Length

The maximum recommended length for DyNet cables between two

network bridges is 800 meters. For cable runs over 300 meters 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 last device. For more information, contact Philips Dynalite.

Read Instructions – We recommend that you read this guide prior

to commencement of installation.

Warning – This is a class A product. In a domestic environment

this product may cause radio interference in which case the user

may be required to take adequate measures.

Special Programming – Once powered and terminated correctly

this device will only operate in basic mode. Advanced functions are

commissioned via the Envision software. If commissioning services

are required, contact your local distributor.

Check Connections – Tighten all load-bearing screw connections,

as vibrations from transport can cause the terminal block screws to

loosen.

Mounting Location – Install in a dry, well-ventilated location.

Data Cable – Use screened, stranded RS485 data cable with three

twisted pairs. Segregate from mains cables by at least 300mm.

Connect devices in a 'daisy chain' configuration. A data cable that

is connected to an energized device is live. Do not cut or terminate

live data cables.

1.

Mount the device on a DIN rail inside an appropriate enclosure.

Alternatively there are 3 holes provided to fix the device to a

surface without the use of DIN rail. Remove the front cover to

access these holes. Pull back the DIN rail clip detail to reveal

the mounting holes.

2.

Connect data cables to the device as per diagrams. Note that

the device is powered from the DyNet network segment that is

connected to Port 1. When implementing Repeaters, connect

the link to Port 2 of both Gateways. Shielded cable must be

used for long runs. When implementing Trunk / Spur topology,

connect the Trunk to Port 2 and the Spur to Port 1. Note that

up to 375mA of power from the DyNet network on Port 1 is fed

to Port 2, so provided there is surplus power available on the

Spurs it is normally not necessary to provide a network power

supply for the Trunk.

3.

If using the device as a DMX receiver, ensure DMX termination

rules are obeyed and use a 120 Ω terminating resistor across

the D+ and D- terminals at the end of the line. Note that Port 2

should be used for DMX Reception.
