Figure 1 Interface Unit Supplied with LTC 5136
The removable terminal blocks have three
connections: (+), (–), and (S [Shield]), as shown in the
diagram above.
Select and maintain a wire color convention to avoid
confusion at the camera site(s).
EXAMPLE: White to (+), Black to (–), and Shield to (S).
NOTE: The shield terminals (S) of the interface unit
are connected to the shield wire of the cable. Skip to
AutoDome Camera or Receiver/Driver Site Configuration
to
complete the installation.

Installation Using RS-232 Data
Direct to Camera Site
(See Figure 5)
In this application, the RS-232 data that is generated
by the Controller is connected directly to RS-232
Series AutoDome cameras or RS-232 Allegiant
Receiver/Driver units. The supplied interface unit is
not used in this application. The AutoDome camera or
receiver/driver must be set (via internal DIP switch or
on-screen menu) for 9600 baud operation.
Install one of the junction boxes supplied in the
LTC 8557 Series Kit (ordered separately) in a location
close enough to the Controller unit so that the supplied
3 m (10 ft) data cable can be used. If desired, four
holes are provided for mounting the LTC 8557 Series
junction box to a flat surface. The power supply (to
power the Controller) should also be located near the
LTC 8557 Series junction box. Connect the bayonet
style connector of the power supply cable into the jack
located on the side of the junction box. 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
junction box. The orientation is not important -- either
end may be connected to either device.
Connect an appropriate length of cable (not supplied),
suitable for use with RS-232 signals, between the
LTC 8557 Series junction box, and the camera site
receiver/driver location. If the distance between the
box and camera site is much over 20-30 m (60-90 ft),
the use of user-supplied short haul modems or other
RS-232 line extender devices may be required. These
devices must be able to support an RS-232 simplex
transmission rate of 9600 baud.
The LTC 8557 Series junction box provides a
removable screw terminal block for the data
connections. The terminal block has four connections,
marked 1, 2, 3, & 4, as shown in the junction box
diagram.

Pins 1 and 2 are not used. Pin 3 is the Controller’s
RS-232 TX output, and Pin 4 is the Signal Ground
connection. Connect the wire from terminal 3 to the
RX connection of the AutoDome camera or receiver/
driver. Respectively, connect the wire from terminal 4
to the data ground connection.
Only a single camera site can be connected in this
manner – RS-232 signals cannot be wired using a
daisy
chain
connection. Be sure to use cable suitable for
RS-232 signals.
