Interlogix KTD-312 RS232 Interface Module/Data Merger, Bi-directional, RS422 Input and Output

The KTD-312 features a DTMF input port. It provides an RJ45 connector for the RS232 interface. All other cable connections are made on a removable terminal strip. An RJ45 connection cable, RJ45-to-DB9 adapter, and 9 VAC power transformer are included with the unit. When used as a computer interface, the KTD-312 establishes a communication link between a Digiplex CCTV control system and an external computer. This feature enables the computer to monitor alarms, download information, and control a variety of Digiplex systemdevices. These include PTZ domes and receivers, matrix switchers, and auxiliary receivers. Components are controlled via seven-character ASCII strings. A limited number of functions may be transmitted from the KTD-312 to the computer via five-character ASCII strings. When operating as a data merger, the KTD-312 can combine two Digiplex RS422 control signals into one common output signal.
