LTC 8786 Series Description
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.
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.
