Use an inexpensive television remote control to control up to three separate devices. Handy if you just want to start up your shop vacuum, or turn off the lamp next to the television. This IC can't drive power line level outputs directly, but with suitable relays or triacs it will provide all the control you are likely to need.

This circuit receives Sony® TV remote control codes from an IR module, and retransmits them as serial ASCII data to a microcontroller or PC. Great for use as an alternative input device for control applications, or as a hidden enabler/disabler for security systems.
Visit the Linux Toys web site to see a complete implementation - the "X Infrared Remote Control". Linux users will appreciate the software provided for converting the ELM622 codes to X-Window keycodes.

This device allows you to talk to your OBD (On Board Diagnostics) equipped vehicle using a standard RS232 serial connection. It transparently converts between a 41.6KHz J1850 PWM data stream (typically used in Ford Motor Company vehicles) and standard ASCII characters. The user need only issue the desired commands - the data formatting, error checking, bus arbitration etc. is all handled by the ELM320. Allows experimenters to inexpensively create their own 'scan tool'.

Similar to the ELM320, the ELM322 allows you to talk to your OBD equipped vehicle using a standard RS232 serial connection. It transparently converts between a 10.4KHz J1850 VPW data stream (typically used in General Motors Corporation vehicles) and standard ASCII characters. The user need only issue the desired commands - the data formatting, error checking, bus arbitration etc. is all handled by the ELM322. Allows experimenters to inexpensively create their own 'scan tool'.

Small control applications often only require a few port pins for outputs and feedback. This 8 pin circuit is perfect for these projects. It is controlled using a PC's serial port with standard 'AT' type commands, allows reconfiguration 'on the fly', and requires only a few external components for support.

Control L or LANC is a standard interface for controlling audio and video devices. It is similar in some ways to RS232, but not enough to allow direct connection to your computer. By using the ELM624, the peculiarities of the interface are translated for you, allowing direct control and monitoring of your favourite A/V machines.

This circuit is designed for remotely resetting devices via an RS232 interface. It connects directly to the RS232 signal lines, requiring only a single resistor, and no external timing components. Complementary outputs and digital selection of break period help simplify circuit integration.

This circuit is similar to the ELM626 but also provides a single 100ms output pulse when powered up. Ideal for many small systems.
