Goddard
Design Co. is pleased to offer these additions to our line of
DMX512
solutions. These single channel cards provide a simple and inexpensive
answer to interfacing individual items to your DMX512 system. It's the
ideal approach for interfacing the mirror ball - practicals - feeds to
house lights - dimmers mounted to scenery. Ideal for any situations
where
you have a stand alone 0-10 volt unit or stand alone switch closure
unit
that has to dance to the DMX tune.
These cards require a user provided DMX connector and a small transformer or source of DC voltage. Mounting is by two #28 holes that may also be used with mounting brackets for edge mounting. The mounting holes are centered on the front edge of the card. The center to center distance is 2.3". The holes are set back .25" from the edge of the card. Each card is about 1" high.

This single channel decoder converts DMX512 to a 0 to 10 volt signal, and features full 512 channel addressing via 3 on board decimal address switches. The DMX1 provides LED displays for monitoring power and data. It may be set to hold last frame or set to send black in the event of a data failure.
Link Settings
LK1 A Blackout on DMX failure. (factory
default)
LK1 B Hold last transmission on DMX
failure.
There is a second output on DMX/One - Decoder. It is designed to drive a solid state relay (5 mA Max). It may be of use when the DMX/ONE is used to drive flourescent dimming ballasts or similar loads.
LK2 A Relay drive high if addressed
slot
is 10% or greater.
LK2B Relay drive high if addressed slot
plus 1 is 10% or greater
Power requirements:
A center tapped transformer providing two outputs of 8 to10 VAC at
80mA or a supply of 12 VDC at 60mA.
External connections are made via an eight pin and a two pin header. Mating IDC connectors are ITW Pancon CE100F24-8,( CE100F24-2) AMP MTA 644775-8 (AMP MTA 644775-2), and AMP HE14-8 27176-8 (AMP HE14-8 27176-2).
