OPERATING VIA A
LIGHTING CONTROLLER
All effects in the Roboscan Pro 1220 are fully DMX 512 and Martin RS-485 implemented, i.e you
can use any DMX board or the Martin 3032 controller to operate it. All control data are transmitted
from the controller’s output, via XLR data link cables, to the data input on the Roboscan Pro 1220
(that is the 3 pin XLR male on the front). The data output (3 pin XLR female) on the Roboscan Pro
1220 allows the serial data link to be continued to further fixtures, and this way up to 16 Roboscans
Pro 1220s can be connected on the same data link.
Connecting the Data Link
You should follow this instruction carefully in order to make a proper serial data link:
1.
Connect the data output on your lighting controller to the data input on the Roboscan Pro
1220. If you are using a Martin lighting controller then use the XLR-XLR / DSUB-XLR cable
supplied with the controller. Otherwise, use a cable that fits your DMX lighting controller and
the Roboscan Pro 1220. This would normally be a cable that adapts from 5 pin XLR to 3 pin
XLR and reverses the (+) and (-) signal wires. The following figure shows the proper connec-
tions in such a cable (P/N 309162). Please note that the (+) and (-) signal wires swap from the
DMX output to the input on the Roboscan Pro 1220.
2.
If you are using one Roboscan Pro 1220 only, then insert a XLR terminating plug into the
unused data output socket on the Pro 1220. If a Martin lighting controller is being used then
insert the termination plug that came with the controller (120 Ohm XLR-male). Otherwise, use
a termination plug as specified by the DMX controller's manual.
3.
If you are using more than one lighting fixture with the controller then connect the data output
on each fixture to the data input on the following fixture using XLR-XLR cables. The order, in
which you connect the fixtures, is not important and has no influence on the channels as far as
the controller is concerned - use an order which gives the easiest and shortest cable routing.
To ensure proper transmission on the data link it is
very important
to insert the XLR terminat-
ing plug in the last fixture in the link.
NOTE: It is possible to insert other DMX fixtures in the link with 5 pin XLR in and out. In that
case you will need a cable that adapts from the 3 pin female output on the Martin fixture to the 5 pin
input on the following DMX fixture. The cable should reverse the (+) and (-) signal wires This
cable is shown in number two of the following figures (P/N 309163).
