  • MicroVision (and FX) Control of Analog Strand CD80 Dimmers

    For MicroVision (and FX) Control of analog Strand CD80 a lot depends on what vintage and configuration of CD80 you have.

    Based on information from Pathway Connectivity and the Fall, 2000 edition of ESTA's Protocol magazine:

    "Four-pin XLR type connectors are newer, and meet the USITT standard for AMX192 connections.  Earlier equipment has TA4/TY4 series Mini-Switchcraft connectors.

    Adapters are required to use TA4/TY4 equipped devices with newer AMX192 devices.  When wiring adapters, you should be aware that the two connectors' pinouts are different.

    Sources (Consoles): MALE
    Receivers (Dimmers): FEMALE

    TA4/TY4 Connectors 
    All equipment: FEMALE
    All cables: MALE/MALE

    NOTE:
    CLOCK+ and CLOCK-  are one twisted pair, ANALOG and COMMON are the other twisted pair."

    The TA4/TY4 connector pin-out for the CD80 was clock- on pin 1, common on pin 2, clock+ on pin 3 and mux analog on pin 4. 

    Depending on when the CD-80 was made, it might use a 4-pin XLR, in which case the cable is 1-1.  However, if it is an older CD-80 pack, with a TA4, then you need the following adapter:

    If the CD-80 pack is analog, as in 0-10vdc, then you need an analog output card [36-pin Centronics on rear panel]
