Figure 5.6: Typical Video Output Module Insertion
The LTC 8934/00 Video Output Modules contain five (5) 8-position dip switches. DIP switch
S1001 is reserved and all switches should be left in the ON position.
Dip switches S1002, S1003, S1004, and S1005 are video termination switches for each of the
video bus inputs. All of these switches should be set to ON (terminated). This is the factory
default.
All LTC 8934/00 Video Output Modules are identical and can be swapped anywhere within the
bay without changing the module.

LTC 8921/00 Video Input Modules
For the LTC 8903 Series Bays, termination switches (S1001 through S1004) on the LTC
8921/00 Video Input Modules must be set to the correct position prior to installation. Read
the Termination Practices section prior to actually installing the Video Input Modules on these
systems. As shipped from the factory, all terminated switches are in the ON (terminated)
position.
Locate and use the diagram(s) that best fit your system configuration (, page 66 to , page
66 in this manual). The appropriate number of Video Input Modules (LTC 8921/00) should be
installed in the LTC 8903 Series main bay, starting with the left most slot. Each input module
handles 32 inputs by 32 outputs.
Since the LTC 8903 Series supplies 64 outputs, two (2) LTC 8921/00 input cards are required
for each set of 32 cameras. Odd numbered slots provide video for monitors 1-32, and even
numbered slots provide video for monitors 33-64. If 32 or less monitors are being served by
the LTC 8903 Series bay, the Video Input Modules are not required in the even numbered
slots. This concept is shown in , page 66 and examples of system configurations are shown
in , page 66.
Cards in even numbered slots should have all termination switches OFF. If looping is not being
used, cards in odd numbered slots should have the termination switches ON. See Termination
Practices for more details.
