PLC-HF10000L Basic Serial Command Functional Specifications5/233 Notes for CommunicationThe projector command is defined one command per line that starts “C” and ends carriage return(0x0D).When the projector receives the carriage return, it starts decoding.There are two types of command, Functional Execution Commands and Status Read Commands.Example of Functional Execution Command: “C05” [CR]Example of Status Read Command: “CR0” [CR]It clears the information of buffer in the following cases.- When the projector receives LF (0x0A) or EOF (0x1A9).- When it takes more than one second to receive a single command.(Until receiving the carriage return after the reception of the first data.)When pipelining control commands, allow interval time as below after the reception of response.1) [ZOOM UP/DOWN] [FOCUS UP/DOWN] [LENS SHIF UP/DOWN/LEFT/RIGHT] commands…100ms2) Other commands…500msWhen pipelining Status Read command, allow at least 500ms of interval time after the response.Do not issue any command before receiving the response except the case that there is no responsefor 5 seconds.It takes about 7 seconds for internal initialization after plugging in AC. During this time, it cannotprocess command. Do not issue any commands.For 7 seconds after starting POWER ON in the status of STANDBY, the projector returns“Acceptable” response, but it does not carry out the command. Status Read commands arecarried out in 500 ms after the “Acceptable” response is returned.About the behavior during Count Down and Cooling Down operation; in the period of the CountDown operation after Power ON or Cooling Down after Power OFF, “Acceptable” response isreturned, but the command is not carried out except for Status Read command.About the behavior during switching inputs; it takes 5 seconds to switch inputs after receiving thecommand. During this period, even if another command is received, it is not carried out althoughreturning “Acceptable” response. However, Status Read commands are carried out in 500 ms afterthe “Acceptable” response is returned.The length of the returned value for Status Read command in successful operation depends on thecommand.The characters for commands must be in uppercase (A - Z). Those in lowercase can not be used
