			Model 2426 has built-in telnet and HTTP servers. Sensoray recommends Telnet for automated control and provides a comprehensive telnet-based API for this purpose. On the other hand, the HTTP server is intended to facilitate manual operation by a human operator (via web browser), and consequently there is no HTTP-based API or protocol documentation.

			Having said that, it is possible for an automated HTTP client to read and program the IOs. In general, IO reads are done via HTTP GET messages and IOs are programmed via HTTP POST messages. You can view the HTTP message protocol in action. To do this, run a web browser in debug mode while you interact with the 2426 module.
