How to turn the controller line from 3-pins into 5-pins (plug and socket)
d. DMX512 Chain with Termination
A DMX terminator is recommended for installations where the DMX cable has
to run a long distance or is in an electrically noisy environment (e.g. discos).
The terminator prevents corruption of the digital control signal by electrical
noise. The DMX terminator is simply an XLR plug with a 120
Ω
resistor
between pins 2 and 3, which is then plugged into the XLR output socket of
the last device in the chain.
Please see illustrations.
e. DMX512 Start Address
All DMX-controlled devices need a digital start address so that the correct device responds to the
signals. This start address is the channel number from which the device starts to “listen” to the DMX
controller. Enter the correct number and read it from the display located on the base of the
VDP250MHS18FL2
.
You can use the same starting address for a whole group of devices or enter an individual one for
every device.
When all devices have the same address, all the
VDP250MHS18FL2
s will “listen” to the control
signal on one particular channel. In other words: changing the settings of one channel will affect all
devices simultaneously. If you set different addresses, each device will “listen” to a separate channel
number. Changing the settings of one channel will only affect the device in question.
In the case of the 18-channel
VDP250MHS18FL2
, you will have to set the start address of the first
VDP250MHS18FL2
to 1, the second
VDP250MHS18FL2
to 19 (1 + 16), the third to 37 (19 + 18)
and so on.
6. Cleaning
and
Maintenance
1. All screws should be tightened and free of corrosion.
2. The housing, visible parts, mounting supports and the installation location (e.g. ceiling,
suspension, trussing) should not be deformed, modified or tampered with e.g. do not drill extra
holes in mounting supports, do not change the location of the connections.
3. Moving mechanic parts must not show any signs of wear and tear.
4. The electric power supply cables must not show any damage. Have a qualified technician
maintain the device.
5. Disconnect the device from the mains prior to maintenance activities.
6. Wipe the device regularly with a moist, lint-free cloth. Do not use alcohol or solvents.
7. There are no user-serviceable parts apart from the lamp and the fuse.
8. Contact your dealer for spare parts if necessary.
WARNING
