[. . . ] NOTE FTDX9000 CAT OPERATION REFERENCE BOOK FTDX9000 OPERATING MANUAL CAT (COMPUTER AIDED TRANSCEIVR) OPERATION OVERVIEW The CAT (Computer Aided Transceiver) System in the FTDX9000 provides control of frequency, VFO, memory, and other settings such as dual-channel memories and diversity reception using an external personal computer. [. . . ] However, the information provided in this chapter explains the serial data structure and opcodes used by the CAT system. This information, along with the short programming examples, is intended to help you start writing programs on your own. As you become more familiar with CAT operation, you can customize programs later on for your operating needs and discover the true operating potential of this system. CONTROL COMMAND A computer control command is composed of an alphabetical command, various parameters, and the terminator that signals the end of the control command. FA Command 14250000 Parameter ; Terminator There is three for the FTDX9000 Command as shown below: Set command: Set a particular condition (to the FTDX9000) Read command: Reads an answer (from the FTDX9000) Answer command: Transmits a condition (from the FTDX9000) For example, note the following in the case of the FA command (Set the main band (VFO-A) frequency): To set the main band (VFO-A) frequency to 14. 250000 MHz, the following command is sent from the computer to the transceiver: "FA14250000;" (Set command) To read the main band (VFO-A) frequency, the following command is sent from the computer to the transceiver: "FA;" (Read command) When the Read command above has been sent, the following command is returned to the computer: "FA14250000;" (Answer command) COM 1 CAT RS-232C "Straght" Cable Page 1 FTDX9000 OPERATING MANUAL CAT (COMPUTER AIDED TRANSCEIVR) OPERATION CONTROL COMMAND Alphabetical Commands A command consists of 2 alphabetical characters. The commands available for this transceiver are listed in the "PC Control Command Tables" on the following pages. For example, when correct parameter is "IS0+1000" (IF SHIFT): IS01000; Not enough parameters specified (No direction (+) given for the IF shift) IS0+100; Not enough digits (Only three frequency digits given) IS0_+_1000; Unnecessary characters between parameters IS0+10000; Too many digits (Five frequency digits given) Note: If a particular parameter is not applicable to the FTDX9000, the parameter digits should be filled using any character except the ASCII control codes (00 to 1Fh) and the terminator (;). Parameters Parameters are used to specify information necessary to implement the desired command.
