Compact design
The LTC 8786 Series of data converters are designed to
convert Bosch "Receiver/Driver and AutoDome RS-232
Control Code Protocol" into Allegiant Bi-Phase control
code.
These units are specifically designed to transform a single
data output from a PC-based 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.boschsecuritysystems.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.
