DZ ILDA Breakout Board (3rd Generation)
Current Status: Out of Stock *In the middle of making the Z-5 Consoles, these will be out of stock for a while*
Hi all, I've just finished testing the new breakout board and it appears everything is working as designed!
Each breakout board will be sold as a complete, fully assembled kit. This will help to ensure that at the end of this run I don't have any parts left over that I have to eat the cost for. So, what you get in the kit is a breakout board, a DB-25M ILDA in cable and a DB-25F Passthru cable. The use of Invert switches are optional, when you receive the breakout board there will be 2 jumpers on each invert pin header, remove these jumpers and install an invert switch to use this feature. To use the invert feature, simply wire a DPDT switch to the crimp pins and connector block. Each breakout board kit will include 12 crimp pins and 2 connector blocks to plug into the two 6 pin headers. Also, the when using the invert switches, this will only invert the signals at the screw terminals, this will not invert the signals on the pass-thru cable.
There are a couple other unique items about the breakout boards that need to be covered. First, is the "-" color channels (-R, -G, -B, -Db, -Ye, -Cy and -i). These are all tied to ILDA pin 25 on the input cable and the output cable. I'm not aware of any confirmed DAC that outputs differential for color, with exception to the early QM2K's, current QM2K's have the "-" color lines tied to pin 25. Having the "-" color lines tied to pin 25 *should* not be an issue for your DAC, if you are unsure, check with the person that created your DAC or ask around here.
The next item is the interlock lock. This 3rd generation breakout board has a completely redesigned loop circuit. Since every projector should have it's own interlock loop, inter-mixing projectors together with passthru cables create problems with these independent loops. So, the breakout board now features an active loop circuit. The passthru cable interlock loop is competely isolated from the ILDA in cable. If the ILDA in loop comes disconnected from the DAC, the passthru cable interlock loop will also go open and interupt the 2nd projector. This is an optional feature to take advantage of, if you do not wish for the passthru interlock loop to be dependent on projector 1's interlock loop being satisfied, then you can attach a jumper to the "bypass" pin header. This will make projector 1 appear as a DAC to projector 2 since projector 1 cannot interupt the passthru cable interlock loop. (Have I lost you yet?!) Ok, in order to make this work correctly, your interlock circuitry in your projector must have a common connection to ground, including the breakout board's GND connection (which is basically ILDA pin 25). You then run the + side of your loop thru what ever makes up your loop circuit, cover switches, EPO switches, etc. Then, that + voltage needs to connect to the "L" screw terminal on the breakout board. This will send the +V out on ILDA pin 4 to your DAC, which will return the +V back on pin 17 which is tied to the "LR" screw terminal. If, +V is present on the "LR" screw terminal, this will feed a small LED on the board to show that the interlock loop is satisfied, it will also feed the base of a transistor, which will close a relay to short ILDA pins 4 and 17 together on the passthru cable. So, if properly working and the bypass does not have a jumper, disconnection from your DAC will open both interlock loops.
Another thing to consider, these boards and being populated with a G5V-1 5VDC relay. If you use an interlock loop that exceeds 5V (I would say that your safe up to 8 or 9VDC), then you may need to replace the relay. I do not have any 12V relays, I did order a couple 24V relays that I'm willing to put on at special request, once they are gone though, I wont stock anymore 24V relays.
That pretty much sums up the new breakout board, if you have questions, please feel free to ask here in this thread or via PM.
Pricing:
10% of each kit sold will be donated to the janitor to help support PhotonLexicon!
Each kit will be $30 shipped within the USA.
I've been having a difficult time determining international shipping, my best estimate leave me to this conclusion, which may go up or down depending on what actually happens at the post office! Shipped worldwide for $30 plus $4 shipped for the first board, additional $2 for each board after that. (Example: 3 boards ($30*3)+4+2+2=$98)
Send me a PM with the number of board kits you'd like to purchase, along with your ship to address and paypal ID, I will send you an invoice from paypal.

edit - I've edited the above information to show that the invert switches will no longer be shipped with the breakout boards. Two things bring me to this decision, first was the issue with the current switches where they have shown to be unreliable at switching low voltage signals. Second, not everyone will want to use this style switch. So, if anyone has a preference, you are welcome to send me the switches you want to use and I will wire them up to the crimp pins and connector block free of charge. If not, I will provide the crimp pins and connector block with the kits so that you can wire them, if you decide to use the invert capabilies of the board. Thanks!
