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.

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. See Figure 2, Junction Box Supplied with LTC 8557 Series Kit.

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.

Next, connect the biphase control code outputs of the interface unit to the data cable. Typically, a single camera site receiver/driver is connected to a single output, but each biphase output of the interface unit is 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). For 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 and the biphase output connections located on the interface unit. The removable terminal blocks have three connections: (+),
Select and maintain a wire color convention to avoid confusion at the camera site(s).

NOTE: The shield terminals of the interface unit are connected to the Shield wire of the cable.
