starting and stopping 7700 fullHD with Arduino over rs232
I am trying to start and stop a 7700 projector with arduino uno using a separate rs232 connection. I have tried using the internal serial.print / serial.write and I have tried creating a separate serial connection with #include . I have a challenge debugging because the commands are in hex. There are also conflicting versions of the commands. in some cases they are listed as 0xBE 0xEF and in others 0xEFBE.
Has anyone successfully controlled their 7700 through the rs232 port? what commands were used? what was the response? Any help would be appreciated. I think I can get past the Arduino issues if I can get the commands to work through a terminal session. that, of course, presents another issue as my laptop (dell) does not see any com ports other than com4 that the arduino is communicating on. it does not have a 9 pin serial port, even on the replicator. I may try and find a desktop machine to use for testing...
