LTC 5136 Series | Instruction Manual | Installation EN | 11 Pin 1 Pin 6 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. 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. 4.3 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 Figure 2 Junction Box Supplied with LTC 8557 Series Kit 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.
