LTC 4629 Transceiver Series is also compatible with the
ENV Series of Bosch AutoDome
®
Cameras that incorporate
an integral fiber optic transceiver.
LTC 4671 Series
The LTC 4671 Series are Transceivers designed especially
for the transmission of RS-485 signals used by system
keyboards in the Allegiant Series of switcher/controller
systems, the Divar Series of digital video recorders, and
the System4 Series of multiplexers. The unit contains
both a transmitter and a receiver operating in the 850 nm
range to allow bidirectional communication using two
fibers between the main control site and its remote
keyboard.
LTC 4651 Series
The LTC 4651 Transceivers are designed especially for the
transmission of Bi-Phase control code signals used in the
Allegiant Series of switcher/controllers, various DVRs,
multiplexers, and other camera control systems. They are
also compatible with Manchester code and standard
RS-232 signals. These units operate in the 850 nm range
and contain a removable screw terminal type connector
that allows easy connection to the shielded twisted pair
cable carrying the control signal. These units can also be
used as an RS-232C transceiver that is compatible with
EIA Standard RS-232C levels. The system is suitable for
simplex asynchronous data transmissions using one fiber,
or full duplex asynchronous data transmissions using two
fibers up to 64 kbaud.
LTC 4637 Series Rack
The LTC 4637 Series Rack Units provide the option to
rack-mount LTC 4600 Series Fiber Optic Modules in a
standard EIA 48 cm (19 in.) rack. The unit incorporates an
integral power supply that supplies power to all modules
installed in the rack-mount unit. The supply also utilizes a
standard IEC AC power connector for easy power cord
replacement or exchange with various worldwide
AC power plug configurations. Modules installed in the
rackmount unit can be hot-swapped, so it is not necessary
to power down the rack when removing or replacing
modules. The integral power supply incorporates an
automatic electronic current limiting feature for each
individual rack-mount slot. This design eliminates the
possibility of a single-point failure causing a complete
shut down of the entire rack. The current limiting function
is also self-resetting, should the fault or overload be of a
temporary or intermittent nature.
