Description

The Control L or LANC interface is an industry standard for many audio and video devices. It uses a bit serial format that is similar to RS232, but differs enough that devices cannot be directly connected to one another. The ELM624 provides the necessary logic to allow almost transparent transfer between the two systems.

In operation, commands are sent to the ELM624 using an RS232 serial connection, translated to the Control L format, and sent to the controlled device on the LANC port. The resulting responses are then converted to a series of ASCII characters and transmitted back to the controlling serial device.
