11421 APPENDIXn ParametersParameters are used to specify informationnecessary to implement the desired command.The parameters to be used for each command arepredetermined. The number of digits assigned toeach parameter is also predetermined. Refer tothe Computer Control Commands and the PCControl Command Tables {page 115} to configurethe appropriate parameters.When configuring parameters, be careful not tomake the following mistakes.(correct parameter: “IS+1000”)IS1000; Not enough parameters specified(No direction given for the IF shift)IS+100; Not enough digits(Only three frequency digits given)IS + 1000; Unnecessary characters betweenparametersIS+10000; Too many digits(Five frequency digits given)Note: If a particular parameter is not applicable to thistransceiver, the parameter digits should be filled using anycharacter except the ASCII control codes (00 to 1Fh) and theterminator (;).n TerminatorTo signal the end of a command, it is necessary touse a semicolon (;). The digit where this specialcharacter must appear differs depending on thecommand used.n Error MessagesIn addition to the Answer command, thetransceiver can send the following errormessages.ErrorMessage Reason for Error• Command syntax was incorrect.• Command was not executed due tothe current status of the transceiver(even though the command syntaxwas correct).A communication error occurred suchas an overrun or framing error during aserial data transmission.Receive data was sent but processingwas not completed.?;E;O;Note: Occasionally this message may notappear due to microprocessor transients in thetransceiver.COMPUTER CONTROL COMMANDSA computer control command is composed of analphabetical command, various parameters, and theterminator that signals the end of the controlcommand.EXAMPLE: Command to set VFO A to 7 MHzAlphabetical command;Terminator00007000000FAParametersCommands can be classified as shown below:Inputcommand(Input to thetransceiver)Outputcommand(From thetransceiver)Set command(Sets aparticular condition)Read command(Reads an answer)Answer command(Transmits a condition)ComputercontrolcommandsFor example, note the following in the case of the FAcommand (Frequency of VFO A):• To set the frequency to 7 MHz, the followingcommand is sent from the computer to thetransceiver:“FA00007000000;” (Set command)• To read the frequency of VFO A, the followingcommand is sent from the computer to thetransceiver:“FA;” (Read command)• When the Read command above has been sent,the following command is returned to thecomputer:“FA00007000000;” (Answer command)Note:uDo not use the control characters 00 to 1Fh since they are eitherignored or cause a “?” answer.uProgram execution may be delayed while turning the Tuningcontrol rapidly.uReceive data is not processed if the frequency is entered fromthe keypad.n Alphabetical CommandsA command consists of 2 alphabetical characters.You may use either lower or upper casecharacters. The commands available for thistransceiver are listed in the PC Control CommandTables {page 115}.
