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.
