1 DESCRIPTION
The LTC 8786 Series of data converters are designed to convert Bosch "Receiver/driver and AutoDome RS-232
Control Code Protocol" into Allegiant biphase control code.
These units are specifically designed to transform the single data output from a DÉSA DVR (or a similar device) into multiple control code outputs for operating AutoDome cameras.
The Bosch "Receiver/driver and AutoDome RS-232 Control
Code Protocol" is a simplex RS-232 data format designed to communicate with the Bosch line of receiver/drivers,
AutoDome cameras, LTC 8786 converters, and other compatible accessory devices. Complete information on the protocol can be obtained by downloading the manual from the AutoDome section of www.boschsecurity.com.
The input RS-232 baud rate of the LTC 8786 Series is fixed at 9600 baud, 1 stop bit, 8 data bits, no parity, and no handshake.
The LTC 8786 Series units can be connected directly to the
RS-232 serial port of a PC using an industry standard null modem cable. If another connection type is required, an interface cable can easily be constructed using the supplied
9-Pin D connector.
The supplied power supply provides power to the LTC 8786
Series unit.

Installation
5 INSTALLATION
5.1
Mounting
The LTC 8786 Series Data Converters are rated for indoor use only. If desired, four (4) holes are provided for mounting the unit to a flat surface. See MOUNTING DIMENSIONS at the end of this document.
If using on a desktop, attach the supplied rubber feet to the bottom of the unit.
A cable suitable for use with RS-232 signals (not supplied) must be used between the RS-232 device and the LTC 8786 unit. If the distance between the RS-232 device and the LTC
8786 unit is over 20-30 meters (60-90 ft), the use of 'short haul modems' (not supplied) or other RS-232 line extender devices may be required. An RS-232 simplex transmission rate of 9600 baud will need to be supported by the link.
5.2
Power Supply Connections
Install the LTC 8786 unit within 1.8m (5.75) of the mains power source. Connect the 'bayonet' style connector of the power supply cable into the jack located on the side of the converter unit. Plug the power supply adapter into a suitable AC power source.
If the power supply must be located beyond 1.8m, the provided power supply cable can be extended, or replaced with an appropriate user-supplied cable. The LTC 8786 is not polarity-sensitive, so it does not matter which direction the cable is attached to the power supply adapter.
If desired, a user-provided power supply may be used with the data converter. A power supply having either a
15-20 VDC ± 10%, 400 mA or 12-18 VAC ± 10%,
400 mA output is required.
If necessary, replacement power supply adapters can be ordered as noted below:
120 VAC input: KBD-120PS Power supply and power cable.
230 VAC input: KBD-220PS Power supply and power cable.
5.3
Data Input Connections
Two (2) data input connections to the converter unit are available. Only one can be used at a time, and the choice varies depending upon the specific application. Although various connection options are possible, typical applications are described in the sections that follow. Use whichever application is most suitable to your configuration. Typical configuration diagrams are included in this manual for reference.
5.4 PC RS-232 Interface Using a 9-Pin
Connector
In this application, the LTC 8786 is connected directly to the serial port of a PC. The user-supplied software installed on the PC must be designed to output "Receiver/driver and
AutoDome RS-232 Control Code Protocol" data. This RS-232 data is converted into Allegiant biphase protocol using the
LTC 8786 unit. The biphase data is then connected to the
AutoDome cameras or Allegiant receiver/driver units as described herein.
Attach an RS-232 standard null modem cable (part No.
S1385) to the serial port of the PC. Connect the other end of the data cable to the 9-pin connector on the LTC 8786 converter unit.
Skip to the section on AUTODOME CAMERA OR
RECEIVER/DRIVER SITE CONFIGURATION to complete the installation.
5.5 RS-232 Interface Using RJ-11
Connector
Connect one end of a suitable data cable to the RJ-11 jack on the LTC 8786 converter unit. The other end of the cable must now be interfaced to the RS-232 communication link.
Only the RX and SIGNAL GROUND connections are required. The remaining pinouts should remain 'un-connected'.
If the distance between the RS-232 communication link and the LTC 8786 converter unit is greater than 3 m (10), install an appropriate length of cable suitable for use with RS-232 signals (user-supplied). Since the data format is an RS-232 simplex transmission, only 2 signal wires (DATA and
GROUND) will be required.
If the distance between the LTC 8786 unit and the camera site is over 20-30 m (60-90 ft), the use of short haul modems
(user-supplied) or other RS-232 line extender devices may be required. They must be able to support an RS-232 simplex transmission rate of 9600 baud.
The wiring pinouts of the LTC 8786 series is shown in the
PINOUTS section.
5.6
Remote RS-232 Device Interface
In this application, Allegiant biphase control code is being converted into RS-232 which is then transmitted over an
RS-232 communication link (fiber optics, microwave, dial-up phone modems, etc.). At the camera side end of the RS-232 transmission link, the RS-232 data is converted back into
Allegiant biphase protocol via the LTC 8786 unit. The biphase data is then connected to AutoDome cameras or
Allegiant receiver/driver units.
The RS-232 communication link must be able to support an
RS-232 simplex transmission rate of 9600 baud.

Operation
5.7 Data Output Connection
The LTC 8786 Series provides sixteen biphase control code outputs. Connect a shielded twisted-pair cable (BELDEN
8760 or equivalent) from a biphase control code output of the converter unit to the camera site. Typically, a single camera site receiver/driver or AutoDome is connected, but the biphase output of the converter unit is rated to handle up to
8 devices 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. Only the last unit in the daisy chain connection should be terminated. All other receiver/drivers should have their terminating resistor removed when the looping cable is connected.
The removable terminal blocks for the biphase code outputs have three connections: (+), (S) (Shield), and (–) for each of the sixteen biphase code outputs as shown in FIGURE 1.
5.8
AutoDome Camera or
Receiver/Driver Site Configuration
Follow the standard installation instructions provided with the AutoDome Camera or Allegiant Series Receiver/Driver unit for setting device address and connecting the data cable to the unit.
Video signals from the camera site are NOT associated with this product. The video signal(s) from the camera site(s) should be connected to an appropriate viewing monitor or other video processing equipment (switcher, PC video capture card, etc.).
6 OPERATION
Operation of the LTC 8786 Series is automatic. An LED, visible on the top cover of the unit, will flash to indicate that the unit has converted RS-232 data into biphase control code. No programming or other user adjustments are required.
