Transparent Remote Serial Driver
Video Server provides a highly customized control support for third-party serial interface devices (other than PTZ cameras). This means that in addition to setting up a custom camera with PAN/ TILT/ ZOOM/ FOCUS commands, users may utilize this mode and introduce a customized homepage to transmit arbitrary user-defined commands from user-side to Video Server. The third-party device connected to the serial port of Video Server will receive the same command sent by the originator. The user only needs to attach the command in ASCII format after the special URL. Video Server will parse the commands and translate into binary code to send out.
Send command to device attached to COM1
/cgi-bin/senddata.cgi?com=1&data=123456,ABCDEF&flush=yes&wait=1000&read=6 This hyperlink will inform Video Server to send out binary format commands to COM1 with “0x12, 0x34, 0x56” followed by “0xAB, 0xCD, 0xEF”. Each comma separates the commands by 200 milliseconds. “flush=yes” means the receive data buffer of COM port must be cleared before
