Applications For The Dng485 - Philips dynalite DNG485 Installation Manual

The DNG485 can be used for several different applications, some of which are described below:
Implementing Trunk/Spur Topology
This style of topology is used in large installations, where there is one or more data trunk cables
that may interconnect DNG485s located at different floors or distribution boards. The other port on
the DNG485 is then connected to a spur that feeds the dimmers and control panels in that locale.
The recommended method of connection is to connect the Spur to the Port 1, and the trunk to the
Port 2. Some reasons for implementing Trunk/Spur topology include:
OPTICAL ISOLATION – A fault on a Spur will be localised to that Spur only, the rest of the system
will be unaffected.
QUANTITY OF NETWORK DEVICES – A finite number of devices can be connected to a single
RS485 data cable. The recommended maximum number of devices is 128. The use of DNG485‟s
gives a maximum of 128 devices per spur, with 128 spurs per trunk, a total of 16384 devices per
trunk. There can be as many trunks as required.

Interfacing To Other Systems
The DNG485 can be used to connect other manufacturers equipment to the Dynalite network. A
common example of this is converting DMX512 into DyNet. When setting up the DMX512 network
ensure that it is connected to Port 2 of the DNG485 and that both ends of the DMX cable are
terminated with 120Ω resistors.
DyNet DC Power Supply
The DNG485 has a 450mA power supply on Port 1 which will supplement the DyNet power supply
available for use by other peripherals.
