out of the box plug and play

paddyk, 06.08.2017
works straight out of the box DMX to analogue converter +ve or -ve voltage 10/12/15V easy to select requires 25 pin D plug to dimmer pack lots of options on this individual to the dimmer pack type
the multi exchanger will work with them all and better value than replacing dimmer packs with newer DMX ones

Very confusing mode of use

Técnico, 01.07.2017
The product was purchased to implement the DMX control in an old dimmer battery with analog voltage control.
The device fulfills its function. However there are certain details of his design that play against him.
As it is a device capable of controlling up to 72 analog channels through three 25-pin d-sub ports, it is likely that it will be necessary to control various equipment with different command and polarity voltages. In such cases this equipment will be very useless, since it has voltage and polarity selections that act on all of the 72 outputs, not allowing different configurations at least in each of the 3 ports, which would be desirable.
The second significant detail is the limited documentary support that accompanies the team, making a simple task such as the construction of the necessary wiring of interconnection between dimmer and device a real headache. There is no reference in the manual on the distribution of the signals on the d-sub 25 (Pin-out) port, so discovering which pins supply each signal (except the common one) must be done by trial / error.
Likewise, there is no guide to the implementation of DMX channels in the manual either. The first DMX channel does not correspond to the first analog channel, but to a "full-on" dimmer control, the second DMX channel being the one corresponding to the first analog channel and so on.
Finally, it is worth mentioning that in this case, the "scene" and "chase" functionalities have not been used because they are not necessary for the application, so they can not be evaluated.
In short a device poorly made in general, although apparently the few existenetes for such use in the market.
