Installation Manual

8903 Series Input Bay configuration must be duplicated for each output bay. The camera
signals to the first input bay configuration are looped using video ribbon cables to the next
group of input bays. This sequence continues for each LTC 8902 Series Output Bay in the
system.Each LTC 8903 Series Input Bay includes one Data Receiver module (LTC 8918) and a
power supply (LTC 8805).
LTC 8934/00 Video Output Modules
The LTC 8934/00 Video Output modules are installed into LTC 8902 Series Output Bays to
provide video output to monitors and DVR/VCRs. Each output module handles 8 outputs. Up
to 8 modules can be installed in each LTC 8902 Series Output Bay.
LTC 8921/00 Video Input Modules
The LTC 8921/00 Video Input modules are installed into LTC 8903 Series Input Bays to accept
input from cameras and other video sources. Each input modules accepts 32 video inputs. Up
to 16 modules can be installed in each LTC 8903 Series Input Bay.
LTC 8943/95 System Controller PC
(Applicable to redundant system configurations only.)
The LTC 8943/95 Series System Controller is an industrial grade PC system supplied in a rack-
mountable enclosure and includes a rack-mounted monitor, a rack-mounted keyboard,
Windows operating system and preloaded configuration software. The LTC 8943/95 PC is
supplied only if the system is purchased in the redundant design configuration.
The PC runs the System Supervisor Software that manages the CPU data mirroring and
automatic switchover functions. Since the PC is intended to configure and monitor the
operation of the LTC 8900 system, Bosch strongly recommends using the PC solely for this
purpose, not as an operator’s workstation or for any other purpose which could interfere with
its ability to provide automatic switchover functions.
LTC 8944/93 and LTC 8945/93 LAN Switches
(Applicable to redundant system configurations only.)
The LTC 8944/93 and LTC 8945/93 units are 10/100Base-T Ethernet LAN switches that
provide a communication link between the LTC 8901 Series main CPU bay and the system’s
LTC 8902 Series and LTC 8903 Series matrix bays. In redundant system configurations, the
LTC 8944/93 and LTC 8945/93 switches are factory-configured to communicate directly with
the LTC 8943/95 System Controller PC.
LTC 8946/93 LAN Switches
The LTC 8946/93 is a 10/100Base-T Ethernet LAN switch that provides a communication link
between the LTC 8904 Series main CPU bay and up to 11 of the system’s LTC 8902 Series and
LTC 8903 Series matrix bays. LTC 8946/93 switches can be cascaded together for use in large
systems to provide additional LAN ports when the number of LTC 8902 Series and LTC 8903
Series matrix bays exceed a combined quantity of 11 in standard configuration systems or 18
in redundant design system configurations.
LTC 8809/00 Video Ribbon Cable
The LTC 8809/00 are 16-channel ribbon cables used to provide video connections between
various system components. They are specifically designed for use with video signals and are
equipped with locking keyed connectors on each end.
