Martin Roboscan 812 / 2504 Controller System, Choose 1 or all, Tested & Works GC

Description

This listing is for my Martin effects lighting system being sold by piece.  There are 5 pieces, a Martin 2504 controller, and 4 ea. Martin 812 Roboscan light units.  You pick which you want, if you want the whole set, please contact me for a system quote that includes shipping.  Best to do that before any units are sold.
I'm the original owner and have taken good care of these.  They all come with their original boxes and styrofoam shipping corner guards.  As the pictures show, they are fully working.  However, being used please note they have marks and wear from age and use.  Unit #010 has a copy of the manual, not the original.  Unit #005 has a few small marks at the edge of the mirror.  The boxes have a fair amount of wear, which is one of the reasons the Roboscans don't.
No cables are included.  Not even the power cords.  These, however, are common 3-prong cords like the ones used for desktop computers in the US.
Returns accepted.  Item must be returned in same condition with all accessories, packing material, manuals.  Buyer pays return shipping.
Please let me know if you have any questions.

MARTIN 2504 LIGHTING CONTROLLER
The Martin 2504 controller is an easy-to-use preprogrammed intelligent lighting controller. The 2504 controller controls up to 8 Roboscans individually, and even more (up to 32 Roboscans) may be connected by allowing several Roboscans share the same control address. Please note that all Sequences and Shows are programmed for 4 or 8 Roboscans, and additional Roboscans on the same address will all perform in exactly the same way.
The 2504 controller lets you choose between 40 preprogrammed Sequences, 5 Shows and a non-repeatable random Sequence. These can be triggered either manually, automatically or by music. It is also possible to enable a total blackout function manually.
The controller has an extra feature, which allows it to convert a standard RS232 input-signal to a Martin RS-485 output-signal. This function can be used for those who wish to control the Roboscans (or other Martin intelligent lights) with their own controller. You may obtain further information about the protocol converting ability from your local Martin dealer.
