For example,
set_ptzcmd_signal(“v1_TU_02”)
The PTZ command work flow
The PTZ translator contains a PTZ command table i.e. ptz.ini in which all the used PTZ commands are defined.
When the HTTP Server receive a CGI function request of sending the “$v1_TD_01” command to a PTZ device for controlling the Camera 1 to Tilt Down with speed 1, it will pass this message to the PTZ translator.
The PTZ translator search the given command in the ptz.ini table to get the ASCII code corresponding to this command. If found the command, the PTZ translator send the ASCII single to the UART to control PTZ device.
