important safeguards
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.
Read Instructions –We recommend that you
read this Instruction Manual prior to
commencement of installation. Retain
instructions and give to the end user.
Troubleshooting - If problems are
encountered, read the troubleshooting section
on page 7.
Special Programming –This device will only
operate in basic modes unless programmed
via a computer. If programming is required,
contact your local agent for details. You
should have all terminations made and be able
to turn all lighting circuits on and off from
control plates before the programming
engineer arrives at the job.
Check Connections –Treat this device as a
switchboard that has been shipped. Tighten all
screw connections, as vibrations from transport
can cause MCB and terminal block screws to
become loose.
Power Sources –This device should only be
operated from the type of supply specified on
the front panel. This device must be earthed.
Data Cable –The recommended cable for
connections to the serial port is screened,
stranded RS485 data cable with three twisted
pairs. Part numbers for various manufacturers
are listed on page 6. This cable should be
segregated from mains cables by a minimum
distance of 300mm. If anticipated cable runs
are over 600 metres for serial cables, consult
your dealer for advice. Do not cut or terminate
live data cables.
Megger Testing –Do not megger test any
circuitry connected to the control system, as
damage to the electronics may result.
Mounting Location –This device should be
mounted with a minimum clearance of 100mm
for all sides, to enable access to the service
switches and LEDs. Install in a dry, well-
ventilated location. (Refer to page 5 for
mounting instructions.)
Warning
TO REDUCE THE RISK OF FIRE OR
ELECTRIC SHOCK, DO NOT EXPOSE
THIS DEVICE TO RAIN OR MOISTURE.
DO NOT ENERGISE UNLESS THE
FRONT COVER IS IN PLACE.
THIS DEVICE MUST BE EARTHED.
INSTALLATION, PROGRAMMING AND
MAINTENANCE MUST BE CARRIED
OUT BY QUALIFIED PERSONNEL.

applications
DNG485 Instruction Manual Rev F.doc 4
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 120Ωresistors.
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.

Select A Suitable Location
This device is designed for indoor use only. If
installing in an external location, the DNG485
must be housed in a suitable well-ventilated
enclosure. Choose a dry location that will be
accessible after the installation is complete.
The DNG485 should be mounted with an air
gap of 100mm on each side and at the top
and bottom of the device. This air gap is
required to ensure the serviceability of the
DNG485 without its complete removal from
the mounting surface and to enable access to
the service switches and LEDs.
Fixing the Device
The DNG485 has integral mounting brackets
attached to the enclosure, designed to
accommodate 4 fixing screws up to 8mm
diameter. The DNG485 can be fixed to the
wall without opening the cabinet or removing
covers. Make sure no dust or other debris
enters the device during installation. Do not
leave the front cover off for any length of
time. Excessive dust and dirt can degrade
internal components.
Allow For Cable Entry
Supply cables enter the enclosure at the top.
If these cables are fed from below the
mounting position, they should be routed
around the enclosure to enter at the top. The
control cables enter at the bottom of the
enclosure. Control cables should never be
run in the mains voltage sections of the
enclosure.
Supply Cable Connections
The supply terminals are located toward the
centre of the enclosure and consists of
Neutral, Phase and an Earth link which will
accept up to two 2.5mm2cables. The supply
cables should have a capacity of 0.5 Amps
minimum. This device must be earthed.

connecting serial control cables
DNG485 Instruction Manual Rev F.doc 6
Serial Cable Connections
There is one RS485 port for DyNet signals, in the
form of a RJ12 socket, on the front panel, which is
used for the temporary connection of a PC or a
Portable Programmer (DPP601). There are data
terminals on the control card, for permanent
connections. The recommended cable for
connections to the serial port is screened,
stranded RS485 data cable with three twisted
pairs. Recommended cable types include:
Belden: 9503
Dynalite DYNET-STP-CABLE
Garland: MCP3S
Hartland: HCK603
M&M Cable: B2003CS
M&M Cable: B9503CS
Multicables: AWM E120236 2092 20
RS Components: 368-687
Dynalite DYNET-STP-CABLE
One pair is paralleled for GND, one pair paralleled
for +VE, and one pair used for DATA+ and DATA-
.Recommended Cable Colour-Coding
Green/White pair Paralleled for GND
Orange/White pair Paralleled for +VE
Blue/White pair Blue for DATA+
White for DATA-
Brown/White pair Spare or Shield
If using unshielded cable terminate the brown pair
to the Shield terminal. The colour-coding scheme
used is not critical, as long as the same scheme is
used throughout the installation.
Serial Cable Connecting Method
The recommended connecting method is to „daisy
chain‟ devices (ie. starting at the first device, then
looping in then out of devices, with a single cable
terminating at the last device. There should not
be any spurs or stubs, and only the first and last
device should terminate one cable, all other
devices should terminate two cables). Devices
may be wired in any order. The Data Cable
should be segregated from any Mains Cables by
at least 300mm, or to meet local wiring rules. A
data cable that is connected to an energised
dimmer is live. Do not cut or terminate live data
cables. If the Data Cable has to cross over any
Mains Cables, it should do so at a 90angle.
Connections for the Left & Right Ports
The Left port is the preferred port for connection
to Dynalite devices such as dimmers and smart
panels on a spur. The Right port is the preferred
port for connection to a data trunk or backbone,
and third party devices such as AV
controllers/touch screens and BMS.

Service Switch and LED
On each side panel of the device is a red LED (Service LED) and a small push button switch
(Service switch).
Service LED
The Service LED has 3 signalling modes, which are useful for troubleshooting:
Normal operation
The Service LED should turn on and off at 50% duty approximately once per second when the
dimmer is operating correctly on a “quiet” network or with no data cable connected.
Network activity detected
When network activity is detected, the Service LED will blink on and off at approximately twice the
normal speed for a few seconds and then revert to normal speed. This will happen even when no
network cable is connected if a control panel is connected to the Control Panel Inputs as the
directly connected panel actually communicates with the dimmer channels via an internal network
connection.
Internal variable updated
When a network message is processed which results in changes to data within the device, the
Service LED will blink rapidly at approximately 5% duty for a few seconds and then revert to
normal.
Service Switch
The Service Switch, when pressed, causes a “sign-on” message to be transmitted onto the
network. If the transmission is successful, the Service LED will indicate “network activity detected”.
The Sign-on message contains information about the device, such as: box number, device type
and embedded software version. This information is captured by DLight configuration software to
speed up commissioning of large systems.
