Fixture Linking
You will need a serial data link to run light shows of one or more fixtures using a DMX-512 controller or to
run synchronized shows of two or more fixtures set to a master/slave operating mode. The combined
number of channels required by all the fixtures on a serial data link determines the number of fixtures the
data link can support.
Important:
Fixtures on a serial data link must be daisy-chained in a single line. To comply with the
EIA-485 standard, no more than 30 devices should be connected on one data link.
Connecting more than 30 fixtures on one serial data link without the use of a DMX optically
isolated splitter may result in deterioration of the digital DMX signal.
Maximum recommended DMX data link distance: 100 meters
Maximum recommended number of fixtures on a DMX data link: 30 fixtures
Data Cabling
To link fixtures together you must obtain data cables. You can purchase DAP Audio certified DMX cables
directly from a dealer/distributor or construct your own cable. If you choose to create your own cable
please use data-grade cables that can carry a high quality signal and are less prone to electromagnetic
interference.

Explanation options DMX port
1. Disp Type
With this option you can choose between two display formats: Hexadecimal (0-F)
or Decimal (0-255).
2. DMX Status
This option is for setting the status of the port. It can be an Output, Input or Disable.
3. DMX Mode
With this option you can set the DMX mode depending on which status the port is
given.
If the port is an Input you can choose between two options: NORMAL or BACKUP.
NORMAL: The DMX port receives the DMX signal and sends it to the first
selected ArtNet universe.
BACKUP: In case of a failure, or when there are no DMX values on the first
selected ArtNet universe for more than 3 seconds, the NET 8/3 automatically
starts sending the DMX values from the backup port.
If the port is an Output you can choose between three options: SINGLE, HTP or LTP.
SINGLE: The DMX signal is sent to the DMX port from the first selected ArtNet
universe.
HTP (Highest Takes Precedence): The DMX signal is sent to the DMX port from
the merging of the 1st and 2nd ArtNet selected universe. It will compare the
values on the inputs and sends the highest value to the DMX port for each
DMX channel in both universes.
LTP (Latest Takes Precedence): The DMX signal is sent to the DMX port from the
merging of the 1st and 2nd ArtNet selected universe. It will compare the values
on the inputs and sends the last changed value to the DMX port for each
DMX channel in both universes.
Note: DMX Merging is when two or more sources of DMX are combined into one
control stream in order to control a single set of lighting fixtures.
For example: You can use two different DMX consoles to control the same lighting
fixtures. The first DMX console with 24 DMX channels on board, controls the first 24
DMX channels. The second DMX console with 24 DMX channels on board, controls
DMX channels 25 till 49.
4. Protocol
This option is for choosing a control protocol, you can choose between ArtNet,
sACN or KlingNet.
5. Framerte/fs
With this option you can set the DMX frames per second which will be sent. The
factory setting is 40 fr/second. You can change it to 10, 15, 20, 25, 30 or 35
fr/second.
6. Network
This option is for defining your network from 0-127.
7. Sub network
This option is for defining your sub network from 0-15.
8. Primary
With this option you can select the 1st Artnet Universe dedicated to this port,
from 0-15.
9. Secondary
With this option you can select the 2nd Artnet Universe dedicated to this port,
from 0-15.
This function only works if the DMX Status is set to Output and DMX Mode is HTP/LTP.
10. Resend
With this option the merged signal from the 1st and 2nd ArtNet selected universe
keeps sending data if there is no activity. You can select to which Artnet universe
(from 0-15 and DISABLED) the data has to be sent to.
This function only works if the DMX Status is set to Output and DMX Mode is HTP/LTP.

03) Mechanically moving parts like axles, eyes and others may not show any traces of wearing.
04) The electric power supply cables must not show any damages or material fatigue.
The Showtec Net-8/3 requires almost no maintenance. However, you should keep the unit clean.
Disconnect the mains power supply and then wipe the cover with a damp cloth. Wipe the front glass
panel clean with glass cleaner and a soft cloth. Do not use alcohol or solvents. Do not immerse in liquid.
Keep connections clean. Disconnect electric power, and then wipe the DMX and audio connections
with a damp cloth. Make sure connections are thoroughly dry before linking equipment or supplying
electric power.
Replacing the Fuse
Power surges, short-circuit or inappropriate electrical power supply may cause a fuse to burn out. If the
fuse burns out, the product will not function whatsoever. If this happens, follow the directions below to do
so.
01) Unplug the unit from electric power source.
02) Insert a flat-headed screwdriver into a slot in the fuse cover. Turn the screwdriver to the left, at the
same time gently push a bit (Turn and Push). The fuse will come out.
03) Remove the used fuse. If brown or unclear, it is burned out.
04) Insert the replacement fuse into the holder where the old fuse was. Reinsert the fuse holder. Be sure
to use a fuse of the same type and specification. See the product specification label for details.
Troubleshooting
No Light
This troubleshooting guide is meant to help solve simple problems.
If a problem occurs, carry out the steps below in sequence until a solution is found. Once the unit
operates properly, do not carry out following steps.
If the light effect does not operate properly, refer servicing to a technician.
Suspect three potential problem areas as: the power supply, the distributor or the fuse.
01) Power supply. Check if the unit is plugged into an appropriate power supply.
02) The distributor. Return the Net-8/3 to your Showtec dealer.
03) The fuse. Replace the fuse. See page 17 for replacing the fuse.
04) If all of the above appears to be O.K., plug the unit in again.
05) If you are unable to determine the cause of the problem, do not open the Net-8/3, as this may
damage the unit and the warranty will become void.
06) Return the device to your Showtec dealer.
No Response to DMX
Response: Suspect the DMX cable or connectors, a controller malfunction, a light effect DMX card
malfunction.
01) Check the DMX setting. Make sure that DMX addresses are correct.
02) Check the DMX cable: Unplug the unit; change the DMX cable; then reconnect to electrical power.
Try your DMX control again.
03) Determine whether the DMX recorder, light controller or light effect is at fault. Does the controller
operate properly with other DMX products ? If not, take the controller in for repair. If so, take the DMX
cable and/or the light effect to a qualified technician.
