Important Safeguards
Read Instructions – We recommend that you read this Instruction Manual prior to the commencement of installation. Retain instructions and give to the end user.
Troubleshooting – If problems are encountered, read the troubleshooting section on page 11.
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 the main cables by a minimum distance of 300mm. If anticipated cable runs are over 600 meters 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 4 for mounting instructions.)
Internal View
Applications
The DTK932V7 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 DTK932V7s located at different
floors or distribution boards. The other port on the DTK932V7 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 Port 1, and
the trunk to Port 2. Some reasons for implementing Trunk/Spur topology
include:
OPTICAL ISOLATION – A fault on a Spur will be localized 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 64.
The use of DTK932s gives a maximum of 64 devices per spur, with 64 spurs per
trunk, a total of 4096 devices per trunk. There can be as many trunks as
required.
Interfacing To Other Systems
The DTK932V7 can be used to connect other manufacturers’ equipment to the Dynalite network. A common example of this is when using AV-type touch screens. The DTK932V7 can be programmed to allow only certain types of messages to pass to the lighting control network, which provides an increased level of network security, and guards against potentially detrimental messages from being accidentally sent by the AV system. High-level interface to other AV or Building Automation System (BMS) protocols can be facilitated with the message translation abilities of the DTK932V7. The DTK932V7 can be set to convert DyNet into DMX512. When setting up the DMX512 network ensure that it is connected to Port 2 of the DTK932V7 and that both ends of the DMX cable are terminated with 120 Ohm resistors.
Mounting & Supply Cable Connections
Select A Suitable Location
This device is designed for indoor use only. If installed in an external
location, the DTK932V7 must be housed in a suitable well-ventilated enclosure.
Choose a dry location, that will be accessible after the installation is
complete. The DTK932V7 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 DTK932V7 without its complete removal from the
mounting surface and to enable access to the service switches and LEDs.
Fixing the Device
The DTK932V7 has integral mounting brackets attached to the enclosure,
designed to accommodate 4 fixing screws up to 8mm in diameter. The DTK932V7
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 center of the enclosure and
consist of Neutral, Phase, and an Earth link which will accept up to two
2.5mm2 cables. The supply cables should have a capacity of 0.5 Amps minimum.
This device must be earthed.
Connecting Serial Control Cables
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 (DTK601). 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
- Garland:
- MCP3S
- Hartland:
- HCK603
- M &M Cable:
- B2003CS
- M &M Cable:
- B9503CS
- Multicables:
- AWM E120236 2092 20
- RS Components:
- 368-687
One pair is paralleled for GND, one pair paralleled for +12V, and one pair used for DATA+ and DATA -.
Recommended Cable Colour-Coding
- Green/White pair
- Paralleled for GND
- Orange/White pair
- Paralleled for +12V
- Blue/White pair
- Blue for DATA+
- White for DATA-
The color-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 energized 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. Both ports have the same connector
arrangements.

The power supply indicator LED lit, but no Service LED activity.| Supply voltage too low, a short circuit on the network, or a short circuit on analog inputs. Control PCB faulty.| Check 5V & 12V terminal voltages. Disconnect the network bus and restore power. Replace control PCB.
The device appears to be operating but not passing messages.| Incorrect Dip Switch settings. Faulty LTC485 Transceiver.| Verify Dip Switch settings. Replace LTC485 Transceiver.
The device passes messages in one direction only.| Incorrect Dip Switch settings. Incorrect software configuration. Message Pass Filter incorrectly set.| Verify Dip Switch settings. Reload the device & verify the Message Pass Filter settings. Re-compile event file.
Hardware Controls
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.
