SETUP
Video Output Module Switches
The 2024VOM (Video Output Module) adds character
information in the form of titles and time and date to switched
video from 2016AVIM modules. Each 2024VOM card
contains 2-pin jumpers and one 8-position DIP switch (see
Figure 28). These are set with the module removed from the
bay.
Four 2-pin jumpers for setting monitor identification are set at
the back of the card (end with gold-plated connections). Each
card can be set for monitors:
one, two, three, and four; or
five, six, seven, and eight; or
nine, ten, eleven, and twelve; or
thirteen, fourteen, fifteen, and sixteen.
There is no other variations, only the four types described
above.
Note: The silkscreen labeling on the VOM board shows which
jumper is for which monitor; these are labeled M1 through
M16. When setting monitors over sixteen, subtract multiples
of sixteen from the monitor number you want to set. For
example, to set monitors 33-36, subtract 32 to obtain monitors
one through four (33-32=1; 35-32=3, etc).
For selection of video type (Phase Adjusted Line, PAL or
National Television Systems Committee, NTSC), locate the
2-position jumper terminal near the center edge of the card.
Position the plastic 2-pin jumper to the appropriate location.
For selection of bay configuration (Standard or Condensed),
locate the 2-position jumper terminal near the center of the two
gold connectors. All bays are configured with the jumper
position set to "standard bay". In Condensed Bays, the jumper
is set to "standard bay" for cards corresponding to monitors 17
to 32, while the jumper is set to "condensed (or split) bay" for
cards corresponding to monitors 1 to 16.
Note: The bay configuration switch was implemented on Rev
"B" boards. Before Rev "B" boards, resistors were placed on
the solder side of the board (Condensed Bays only).
The 8-position DIP switch S2, located on the circuit board,
must be set to identify the video inputs and outputs the module
must respond to. Switch settings are dependent on the slot
location in the matrix bay as well as which matrix bay the card
is located. Switch settings are shown in Tables 4a, 4b, and 5.
Table 4 represents the first four switches of S2, which
identifies video input. If the video output is located in a matrix
switching bay that includes video input cards its video input
would be considered internal. If the video output card is
located in a matrix switching bay which contained only output
cards its video inputs would be considered external.
Table 5, on page 17, identifies which video outputs the card
will be controlling.

Note: Table 4a is used when the 2024VOM is located in a
matrix switching bay which includes 2016AVIM. Table 4b is
used when the 2024VOM is located in a matrix switching bay
which does not include 2016AVIM modules. In both
instances, the Filter DIP switch S2 on the 2010DB/2010DBVL
Data Buffer Module must be set to pass all data (see page 12).
DIP Switch S1 and slide Switch S3 are not used on the
2024VOM card.
