CAT (COMPUTER AIDED TRANSCEIVER) OPERATION FT-450 CAT OPERATION REFERENCE BOOK FT-450 CAT OPERATION REFERENCE BOOK CAT (COMPUTER AIDED TRANSCEIVER) OPERATION OVERVIEW The CAT (Computer Aided Transceiver) System in the FT-450 provides control of frequency, VFO, memory, and other settings such as dual-channel memories and diversity reception using an external personal computer. This allows multiple control operations to be fully automated as single mouse clicks or keystroke operations on the computer keyboard. The FT-450 has a built-in level converter, allowing direct connection from the rear-panel CAT jack to the serial port of your computer without the need of any external boxes. You will need a serial cable for connection to the RS-232C (serial or COM port) connector on your computer. Purchase a standard serial cable (not the so-called "null modem" type), ensuring it has the correct gender and number of pins (some serial COM port connectors use a 9-pin rather than 25-pin configuration). If your computer uses a custom connector, you may have to construct the cable. In this case, refer to the technical documentation supplied with your computer for correct data connection. Vertex Standard does not produce CAT System operating software due to the wide variety of personal computers and operating systems in use today. 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. CAT JACK PIN NO. PIN NAME N/A SERIAL OUT SERIAL IN N/A GND N/A RTS I/O --Output Input ------Input CTS Output N/A --- FUNCTION --Outputs the Serial Data from the transceiver to the computer. Inputs the Serial Data from the computer to the transceiver. --Signal Ground --When the computer is not ready to receive data, this port goes "L" to inhibit transmit data from the transceiver. When the transceiver is not ready to receive data, this port goes "L" to inhibit the transmit data from the computer. --- COM INPUT DC 13. 8V 22A ANT DATA TUNER LINEAR CAT EXT GND SPKR CAT RS-232C "Straight" Cable Page 1 FT-450 CAT OPERATION REFERENCE BOOK CAT (COMPUTER AIDED TRANSCEIVER) OPERATION 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. Example: Set the VFO-A frequency to 14.250000 MHz. FA Command 14250000 Parameter ; Terminator Parameters Parameters are used to specify information necessary to implement the desired command. The parameters to be used for each command are predetermined. The number of digits assigned to each parameter is also predetermined. Refer to the "Control Command List" and the "Control Command Tables" to configure the appropriate parameters. When configuring parameters, be careful not to make the following mistakes. 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 FT450, the parameter digits should be filled using any character except the ASCII control codes (00 to 1Fh) and the terminator (;). There are three types of commands for the FT-450 as shown below: Set command: Set a particular condition (to the FT-450) Read command: Reads an answer (from the FT-450) Answer command: Transmits a condition (from the FT-450) For example, note the following in the case of the FA command (Set the VFO-A frequency): To set the VFO-A frequency to 14.250000 MHz, the following command is sent from the computer to the transceiver: "FA14250000;" (Set command) To read the 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) Alphabetical Commands A command consists of 2 alphabetical characters. You may use either lower or upper case characters. The commands available for this transceiver are listed in the "PC Control Command Tables" on the following pages. Terminator To signal the end of a command, it is necessary to use a semicolon (;). The digit where this special character must appear differs depending on the command used.
