ELM624 Control L (LANC) to RS232 Interpreter
Description
The Control L or LANC interface is an industry standard introduced by the Sony Corporation for controlling audio and video devices. It uses a bit serial data format, and requires that the controller be synchronized to the controlled device – something which is difficult to do using standard serial interfaces. The ELM624 is an 8 pin integrated circuit that performs the synchronizing function for you.
All user interaction with the ELM624 is by standard ASCII characters over an RS232 interface. There is no special formatting required, other than perhaps an understanding of the hexadecimal numbering system, nor is there a need for a powerful PC - virtually any model with a serial port will do.
