4 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.
