PLC-XC50/55 Expand Serial Command Functional Specifications9/673. Notes for communication3.1 Expand Serial Command is defined as one command / one line that starts with “C” and ends withcarriage return (0x0D)3.2 There are two types of commands: Functional Execution Command and Status Read Command.- Example of Functional Execution Command:”CF_BRIGHT_032”[CR]- Example of Status Read Command: “CR_RIGHT”[CR]Note) ”_” means a space3.3 When it takes more than one second to receive one command, it is not executed.When it takes more than one second to receive carriage return (0X0D) after the projector receivesthe first data “C”, it clears the information of buffer.3.4 On command pipelining, wait for the interval of 100ms till sending next command after receiving aresponse.(More than 100ms)CommandPC → Projector “CF_BRIGHT_032” CR Next CommandProjector → PC “000” CRResponse(A few ms - 5s)3.4.1 When a computer sends next command before receiving a response, the projector maynot operate properly.3.4.2 Except when there is no response for more than 5 seconds.3.5 It takes about 5 seconds for internal initialization after plugging in AC power. During this timecommands cannot be processed. Do not issue any command.4.
