Question poster's level of knowledge: BEGINNER/NOVICE/MENTALLY CHALLENGED
A stage lighting pan/tilt motor, for one axis. Used in sets of two to provide remotely controlled X and Y movement of a spotlight.
It has been designed to be controlled indirectly THROUGH a followspot light fixture, which itself is DMX controlled. The DMX movement instructions sent to the light are sent to the LIGHT, and then are 'forwarded' to each of two motors over Cat5 cable by the light. The Cat5 is 'daisy-chained' such that the connections look like this: DMX_CABLE_INPUT_TO_LIGHT>LIGHT>Cat5CABLE1>MOTOR1>Cat5CABLE2>MOTOR2
Use motor control devices without having a light fixture
translating and forwarding the commands to the motor controller.
Reason for goal:
I have many of these motor units, but do not own the light fixture they are controlled by. I want to use the motors for the same purpose, but on different objects (Eg – a different model of follow-spot and/or other lighting).
I have made magic smoke come out one as I attempted to figure out what it's power requirements are. 5v makes it smoke. I don't want to ruin any more by guessing and hoping, because I actually want to use these, not just experiment with them.
J1 on the RJ45 input board connects to BOTH J2 and J3 on the main board. The two pins on J1 closest to the "J1" label connect to J3 on the main board, and these seem to me to be the power input pins for the board as well as the motor.
I am working under the assumption that if I can supply power to the boards properly, I can then begin to explore how to address it using the DMX protocol, since the DMX protocol is 'knowable' via Google and it's voltages/signal are searchable. The boards, it seems, are not Google-able.
Also – Forgive me for my awful diagram.
QUESTION, IN THREE PARTS:
1) Can the power needs of the board be determined by visual inspection?
2) If the answer to number 1) is 'yes': What is that power need?
3) If the answer to number 1) is 'yes': How was this determined, in terms a novice might understand?
