Web Control of Device across LAN - Need ASAP -Small Project-Good Pay
Essentially, we are looking to send commands from a web page, signals from a virtual hand-held infrared remote control through a LAN to a VCR and/or Satellite receiver (e.g. play, stop , channel up/down, etc.). This is through control of a Global Cache GC-100 ( http://www.globalcache.com/products/gc-models.html ) network adapter that converts Ethernet to serial infrared. It operates at a typical 192.168.1.70 on port 4998.
All we need to do is send an IR command (e.g. power on) to the device that is linked from a web button. We can build the button graphics and the IR command library . We only need the code to establish the TCP device connection and command syntax. Then we can replicate for each command on the hand held remote control.
The IR code remote control signals are in binary ccf codes. We will convert these serial IR commands to a compatible format for the GC-100 Ethernet device.
The Global Cache API can be obtained at : http://www.globalcache.com/files/Documentation/021222-01_APISpecv2.pdf
ALTERNATE - Serial Tunneling
If the Global Cache is determined to be too difficult or costly to develop, we can use a Lantronix Ethernet to Serial device server (like a print server) model UDS-100 (
http://www.lantronix.com/products/ds/uds100/index.html ) Lantronix has a com port redirector application ( download at http://www.lantronix.com/support/utils/redirector/index.html ). This application simply re-directs com port commands to their device at the designated IP address on the LAN. This device would hook to a Serial to IR converter (functionally just 2 LEDs hooked to the Tx and Rx pins on the RS232 connector). We could then use JavaScript code with Server Side Include statements to execute the IR commands stored on the local server. Like before, this would be liked to a web user interface
Any recommendations would be appreciated. We are hoping to get something functional by the end of next week.
Thanks!
