LTC 8780 Series Data Converter Units

6.14 LTC 8780 Series Data Converter Units

The LTC 8780 Series are accessory units that convert the Allegiant system's biphase control code into RS-232, or converts RS-232 back to biphase code. This provides the capability of transmitting the control code over conventional RS-232 transmis- sion mediums such as phone modems, fiber optics, microwaves, etc. The unit will accept the Biphase control code generated by an Allegiant main CPU bay, an LTC 8568/00 Signal Distribution unit, or an output from an LTC 8569, an

LTC 8570, an LTC 8571, or an LTC 8572 Series Code Merger unit.

6.15 LTC 8781 Series Data Converter Units

The LTC 8781 Series are accessory units that decode the Allegiant system's encoded time/date information generated on the biphase control code line and convert it into an RS-422 GPS format. This time/date information can be used to interface into external time/date inserter products (such as the Kalatel KTS-53-16), which are designed to be synchronized via a GPS signal.

6.16 LTC 8016/90 Bilinx™ Data Interface Unit

The LTC 8016/90 Allegiant Bilinx Data Interface unit is an accessory used for com- municating over-the-coax, with up to 16 Bilinx-capable AutoDome and/or Dinion™ Series cameras. The LTC 8016 provides complete control of pan/tilt/zoom, auxilia- ries, and pre-position functions of Bilinx enabled AutoDome Series cameras. In addition, complete programming of Dinion Series cameras and AutoDomes via their on-screen menus is supported. Bilinx technology also supports camera-gener- ated event reporting to the Allegiant. This connection allows remote alarm inputs and motion event data to be sent by the camera to the Allegiant without the need for additional wiring between the camera site and the main control location. The LTC 8016 can also be used to transmit Bilinx communications over a number of video transmission systems. Example devices include fiber optic links and external balun devices that use CAT5 twisted pair cables for video communication.

6.17 LTC 8785 Series Code Converters

The LTC 8785 Series code converter units are designed for use in older Allegiant systems that have been upgraded to support 'variable speed' control code protocol. The LTC 8785 units are used to provide a source of 'fixed speed' control code when the system is generating the newer 'variable speed' control code preferred by the AutoDome Series of PTZ cameras. The LTC 8785 would receive the variable speed control code from the Allegiant via its LTC 8568/00 Signal Distribution unit and convert it into the appropriate fixed speed control code. The 'fixed speed' control code outputs from the LTC 8785 Series connect to the older TC8561 Series receiver/ drivers using the existing field cabling.

6.18 LTC 8782 Series Code Translator Units

The LTC 8782 Series Code Translators are accessory units that convert biphase code to other manufacturers’ control codes, or convert other manufacturers’ codes to
