Transcripts:

[16:11]        Rick: Hello, how may I help you.

[16:12] Customer: Hi, I recently bought an Elite Screens Spectrum, 125-inch Diag 16:9, Electric online

[16:12] Customer: I’m trying to setup the 12V trigger to open the screen when I turn on my projector.

[16:13] Customer: I have found a mono 3.5mm cable from Projector 12V and measured the current with multimeter it shows 12V.

[16:13] Customer: However, after connecting with 12V trigger cable cat5-- the screen is not opening.

[16:14] Customer: Elite screen trigger has - Red and Green wires on end and other cat5 goes to screen.

[16:14]        Rick: Okay if the unit is not responding please check the polarity. Here is how. Red is positive and green is negative.

[16:15]        Rick: You can use a 9V battery to test the trigger.

[16:15] Customer: 3.5mm has Red and white wires

[16:15] Customer: a 9V battery can open the screen?

[16:16]        Rick: Yes, the 9v battery simulates the projector once you connect the green/red wire to its terminals the screen will deploy and once your remove the battery the unit will retract on its own.

[16:16]        Rick: This is a good for testing the 12 volt trigger and its wires.

[16:17] Customer: Ok just in case checking Green is -ve ? red is +ve?

[16:17]        Rick: Also, check your projector setting if the 12 v trigger out is on.

[16:18]        Rick: Your last comment is correct. You will be able to confirm the polarity of the wires using the battery method.

[16:18] Customer: Yes I have called Optima tech support and they showed how to Turn ON 12V trigger in the menu.

[16:19] Customer: 3.5mm cable I have got from Amazon has Red and white wires. From the video you sent it shows Red and Green.

[16:21]        Rick: Red will go with red and green with white cable.

[16:22] Customer: OK that’s how i have twist the wires.

[16:22] Customer: Let me check with Batteries

[16:22] Customer: 9v battery confirms that 12V trigger cable is good or bad right?

[16:23]        Rick: Correct. If you have a bad wire, you can make your own with an Ethernet RJ45 cable. You can use pin 7 and 8, these are the brown pair wires.

[16:24]        Rick: 7 is positive and 8 is the negative. Also, check the polarity and make sure it is a mono jack and not an audio jack.

[16:24] Customer: Okay,  looks like I had a bad connection because everything is working fine now.

[16:24] Customer: Thanks for the information

[16:24]        Rick: My pleasure, I’m glad to help.

[16:24] Customer: Thanks again.
