Professional Video Distribution Switch: CNX-PVID8x4
Operations Guide - DOC. 8166A
Conditions of this configuration;
please read carefully!
This configuration allows for up to 24 sources. However, those sources cannot
exceed more than eight component, more than 16 S-video (assuming no component
sources), more than 24 composite (when there is no S-video and no component). The
illustration after this paragraph provides a visual depiction of a system that utilizes
the limited quantity of any-type configuration. Some of the sources also include
digital audio. Notice that component sources can only be connected to input 9
through 16 (levels 1, 2, & 3) and that S-video sources can only connect to input 1
through 8 (levels 1 and 2). Installation of the cable assembly and removal of jumpers
splits level 3 (thus component sources are restricted to inputs 9 through 16) and
extends level 1 with eight composite-only connections. Of course, if there are fewer
than eight component (or eight S-video) sources in the system, the number of
S-video and/or composite sources can increase as long as the total number of sources
does not exceed 24.

Cabling and Jumpering Internal
Boards:
Cable between level 1 and level 3
is in place.
Nine jumpers are removed from
their original location and stored
on the jumper holder.
**S-VIDEO SOURCES CAN CONNECT TO
LEVELS 1 OR 2, INPUTS 9 THROUGH 16
(WHEN THERE ARE LESS THAN
EIGHT COMPONENT SOURCES).
HOWEVER, THE TOTAL NUMBER OF
S-VIDEO AND COMPONENT
SOURCES CANNOT EXCEED 16.
COMPONENT SOURCES:
PHYSICALLY CONNECT TO LEVELS 1, 2, & 3
(INPUTS 9 THROUGH 16) ONLY.
DIGITAL AUDIO (IF AVAILABLE):
PHYSICALLY CONNECTS TO LEVEL 4 AND IS
SWITCHED WITH COMPOSITE, S-VIDEO, OR
COMPONENT SOURCES, BUT NOT ON THE
SAME INPUT NUMBER.
EIGHT (OR
MORE) COMPOSITE
SOURCES*
ARE PERMITTED.
EIGHT (OR
MORE) S-VIDEO
SOURCES**
ARE PERMITTED.
UP TO EIGHT
COMPONENT
SOURCES ARE
PERMITTED.
NOTE:
THE LABELING OF INPUTS 17
THROUGH 24 BECOMES USEFUL
WHEN PROGRAMMING.
NOTE:
THE SAME IS TRUE FOR PAIRED INPUTS 2&18,
3&19, UP TO 8&24. HOWEVER, WHEN
PROGRAMMING DIGITAL AUDIO, USE THE
INPUT NUMBER LESS THAN 8.
DIGITAL AUDIO CAN ONLY BE DISTRIBUTED
FOR A TOTAL OF 16 SOURCES. IF DIGITAL
AUDIO IS DISTRIBUTED WITH THE S-VIDEO
DEVICE CONNECTED TO INPUT 1, INPUT 17
WOULD BE PROHIBITED FROM USING LEVEL
4 FOR DIGITAL AUDIO (AND VICE VERSA).
