LTC 8903 Series Camera bays will always be providing video signals (either directly, or via
asecond LTC 8903 Series bay) to a specific LTC 8902 Series Monitor bay. Determine the
applicable LTC 8902 Series Monitor bay, then set switches 5 through 7 on dipswitch S2 to the
same settings as switches 5 through 7 on S2 of the Data Receiver module installed in the
corresponding LTC 8902 Series bay. These will be the same settings as listed in the Monitor
Number Range shown in , page 23.ON dipswitch S2 of the LTC 8918, verify that switch 8 is
ON.If switch 4 on S1 has been set to the ON position (for use as a secondary camera bay as
described above) set switches 3 and 4 of S2 OFF and set switches 1 and 2 of S2 according to
which primary camera bays it will be connected to per , page 24 below:

LTC 8934/00 Video Output Modules
The appropriate number of LTC 8934/00 Video Output Modules should be installed in the LTC
8902 Series main bay starting with the left most slot. Each output module handles 8 outputs.
If fewer than the maximum number of Video Output Modules are installed, they should be
installed from left to right, with empty spaces on the right.
In some system configurations, 8 or less LTC 8934/00 modules may be distributed between
two (2) LTC 8902 Series Video Output bays. This configuration assures partial system
operation in the unlikely event of an LTC 8902 Series failure. Since this creates a gap in the
monitor number order, the optional Allegiant PC-based system software allows renumbering
of the logical monitor numbers. For example, if the system was designed for 64 monitor
outputs, four LTC 8934/00 modules (handling monitors 1 to 32) would be installed in the first
LTC 8902 Series bay. Another four LTC 8934/00 modules would be installed in a second LTC
8902 Series bay. The default monitor number range for this second module would be 65 to 96.
Since this would be inconvenient to operators of the system, the logical numbers of the
monitor numbers in the second bay can be renumbered to range from 33 to 64 using the
optional Allegiant PC-based system software. , page 35 shows an example of this type of
configuration. It is also possible to number the monitors so that one bay contains the odd
numbered monitors and the other bay contains even numbered monitors. This way, a viewing
location containing an even mix of monitors from each bay would lose every other one in the
unlikely event of a LTC 8902 Series bay failure.
