INSTALLATION
4.1
General
The desktop Controller unit should be installed in a
location convenient to the operator. The Controller
contains a single RJ-11 connector, which is used for
both power and data connections. In most applications,
the supplied 3 m (10 ft) power/data cable is connected
directly to the supplied interface unit. The interface
unit converts the RS-232 data generated by the
Controller unit into Allegiant biphase control code.
The interface unit also provides a path to connect
power to the Controller unit.
An LED visible on the top cover of the interface unit
will flash to indicate that the RS-232 data coming from
the Controller has successfully been converted into
biphase control code.
There are no video connections to the Controller. The
video signal(s) from the camera site(s) should be
connected to an appropriate viewing monitor, or other
video processing equipment (switcher, multiplexer,
etc.).
If the application will utilize an RS-232 data
communication link, or will be connected directly to
RS-232 Series AutoDome cameras or RS-232 Allegiant
Receiver/Driver units, the installation is done without
using the supplied interface unit. For RS-232
applications, an LTC 8557 Series Remote Keyboard
Hookup Kit should be purchased to simplify the
installation process. One of the junction boxes supplied
with the LTC 8557 Series Kit can then be used to
connect the RS-232 wires TX and GND from the
Controller's output to the user-supplied RS-232
communication link. The RS-232 protocol requires a
simplex link operating at 9600 baud.
Three installation sections are detailed below; select
the type of application you will be using.
This document also includes various diagrams of
typical applications, that will be helpful to refer to
during installation.

4.2 Installation Using Biphase Code
(See Figures 3 and 4)
Install the supplied interface unit in a location close
enough to the Controller unit so the that supplied
3 m (10 ft) data cable can be used. Note that the
interface unit is rated for indoor use only. If desired,
four holes are provided for mounting the interface unit
to a flat surface. The power supply (to power the
Controller and interface unit) should also be located in
a convenient location near the interface unit. Connect
the bayonet style connector of the power supply cable
into the jack located on the side of the interface unit. If
the power supply cable must be attached to the power
supply, the polarity is not important; the Interface Unit
is not polarity sensitive. Plug the power supply into a
suitable AC power source.
Connect the supplied 3 m (10 ft) data cable with two
RJ-11 connectors, between the Controller unit and the
interface unit. The orientation is not important -- either
end may be connected to either device.
The next step is to connect the biphase control code
outputs of the interface unit to the data cables.
Typically, a single camera site receiver/driver can be
connected to each output, but the outputs of the
interface unit are rated to handle up to eight (8)
receiver/drivers when connected in a daisy chain
configuration, to a maximum of 1.5 km (5000 ft). In a
daisy chain connection, the cable is looped through each
AutoDome camera or receiver/driver along the way.
The last (and only the last) unit in the daisy chain
connection should be terminated. All other receiver/
drivers should have the terminating resistor removed
when the looping cable is connected.
Connect shielded twisted pair cable (Belden 8760 or
equivalent) between the camera site receiver/driver
location and the biphase output connections located on
the interface unit.
