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.
