Anybody have any idea what the wiring for this connector is? Since I didn't get the remotes and control box I have no way to figure it out
I would like to connect a hard wired three position switch to it like dalite supplies. Any ideas would be greatly appreciated
IMPORTANT TIP TO OTHER OWNERS:
I took off the end cap on the connector end of the screen to try to figure out the wiring, and noticed that one of the pins is a green wire with a spade terrminal on it which was just hanging loose inside....guess the screw it was under came loose from shipping - worth checking - several other screws found loose.
My screen came hard wired to the control box, no connector such as yours. The four wires from my control box to the screen are AC power wires for the motors two for up and two for down. One could plug these wires directly into the wall and control the screen. There are limiters on the motors so if the screen reaches the end and is still plugged in it stops it's self. The control box is nothing more than a relay with a timer. It simply applies power to the motor for a certain amount of time, a minute or so after the screen as finished traveling, and then cuts the power. It also serves as the remote receiver which simply trips the relays the same as the buttons, except the remote never worked.
In short, if your screen is wired the same as mine, you could use any type of switch, relay or control that would turn the power on and off to the correct pair of wires. A three way toggle switch that is "On" when in either the up or down position and off in the middle would work.
The stop button on mine actually is the same as whichever button was not pressed last. If the screen is traveling down then pushing the stop button or up button stops the screen and if it's traveling up then stop or down stops the screen. If I need to stop travel with my rigged remote control which only has up or down then pushing the one opposite of travel works just the same as having a stop button.
Hope this helps, yes it's a cheap crappy screen but it's worked well for me so far and these days I use it almost every day. I'm using it now.
By the way, the green wire would be the ground or the round pin in a wall plug. Since my screen does not use standard color coding I would highly suggest letting an electrician look at it before trying to connect it. The connector can be found at mcmelectronics.com and I think it is called a CB plug. I had to buy one several years ago but I think they still carry them.
