    Default Single laser setup

    someone who have tried to use a CAT5 or CAT6 cable as a ilda cable?
    25pin connector in one end(from laser controller) and a JR45 plug in the other. (to projector) Ofcource in the projector has a jr45 female and wired to galvos/laser/ground etc..

    regards

    Big Fan or CAT5 here... I use them for DMX for a long time and been using it lately for my projector (one color).
    made 2 ILDA/CAT5 female short cables, and use a regular CAT5 cable to connect them.

    they are excellent for DMX as they are 100ohm which is what RS485 wants

    Evening All!
    Brought a bunch of chinese scanners recently, very reasonably priced and not bad for for beam shows, graphics at 15kpss ish. Anyway, the pre-loaded 'show board' came with one of these handy little chaps:

    You know, because of the differential nature of ILDA signals, it is appropriate to use unshielded twisted pair cables instead of D-25 cables. You can use ordinary CAT-5 flexible network cables, and buy D-25 to RJ-45 adapters at each end for $1.50 (e.g. http://www.pccables.com/01915.htm, http://www.pccables.com/01916.htm). You can also use the common type of RJ-45 joiners along the cable without any problem.

    The advantage of this technique is that CAT-5 network cable is lighter and more flexible than D-25 cable, it's also cheaper and easier to buy in long lengths. In typical circumstances, signal degradation should be unnoticable over a 500ft cable. With good quality line drivers and receivers, much longer lengths are possible.

    One important point of this technique is that you must use ILDA-compliant DACs (which produce differential signals), and amplifiers which sample the differential signals. Also, remember that the +/- components of each signal must use the same twisted pair. Some cheaper DACs only produce single-ended signals, and some cheaper amplifiers only sample single-ended signals. If you use either of these, you must put the DAC quite close to the projector because there is no way to use long ILDA cables without signal degradation. You will even notice it using high quality and shielded D-25 cables.

    CAT-5 network cable is ideal for single colour projectors, because there are four pairs which can be used for X, Y, blanking/intensity, and ILDA interlock. If you have an RGB projector, you need to use another type of cable which has more pairs, or use two CAT-5 network cables in parallel.

    Best regards,
