Parallel Digital Video Cable
PARALLEL DIGITAL VIDEO INTERFACE STANDARD CCIR 656 satisfied cable
MOGAMI Part No. W3037. MOGAMI Parallel Digital Video Interface Cable is
available from stock as well as the only one existing cable in the world
now that meets the computer interface SCSI - II. It resembles others in
execution of very high speed transmittance through twisted pair conductors
in parallel, though there is a slight difference in applicable frequency
and difference between balanced (differential) for digital video and unbalanced
(single ended) for SCSI.

| WIRING INSTRUCTION: |
Use YELLOW COLOURED INSULATION TWISTED PAIR only for
CLOCK SIGNAL, as the pitch of this twisted pair is made shorter
than other twisted pairs. |

How much the difference of delay time between each pair can be made smaller is the key to how long the
cable can be used, as the transmitted parallel signals must be received at the same time in the parallel
digital video interface (fast parallel transmittance) system. Therefore, specification of #W3037 parallel
digital video cable is subject to change without notice, as it may be improved for longer distance
application.
