Mykerinos Connection

• J6 – 16 pin ribbon cable to the primary (master) Mykerinos card for TimeCode and sync. In order for

the MTCHIO Sync board’s TimeCode & Video functionalities to be fully operational, it is necessary to

connect the J6 socket to the primary (TimeCode Master) Mykerinos card, with the 16 pin ribbon cable

provided. In multi-board systems, by convention, the primary Mykerinos card is the one fitted in the PCI

slot closest to the graphics adapter. Note: video termination Jumper 4 on the TimeCode Master

Mykerinos should be set to OPEN when used in conjunction with MTCHIO.)
