KENWOOD will not support or warrantee this documentation in any
2、 way. HARDWARE DESCRIPTION The TS-480 transceiver uses a full-duplex, asynchronous, serial interface for communicating through the male 9-pin D-sub connector. Each data is constructed with 1 start bit, 8 data bits, and 1 stop bit (4800 bps must be configured as 2 stop bits). No parity is used. The p

TXD:Receive data is serial data transferred from the computer to the transceiver. GND:Signal ground pin RTS:This signal is applied to the transceiver. It is used to inhibit transmit d

It is used to inhibit transmit data from the computer when the transceiver is not ready to receive data. Transmit data is stoppe
6、d when the level is low. CONTROL OPERATION Most computers handle data in the form of “bits” and “bytes”. A bit is the smallest piece of information that a computer can handle. A byte is composed of eight bits. This is the most convenient form for most computer data. This data may be sent in the form
7、 of either serial or parallel data strings. The parallel method is faster but more complicated, while the serial method is slower and requires less complicated equipment. The serial form is, therefore, a less expensive alternative. Serial data transmission uses time-division methods over a single li
8、ne. Using a single line also offers the advantage of reducing the number of errors due to line noise. Only 3 lines are required theoretically for control of the transceiver via the computer: Transmit data Receive data Ground From a practical standpoint, it is also necessary to incorporate some means
9、 of controlling when this data transfer will occur. The computer and transceiver cannot be allowed to send data at the same time! The required control is achieved by using the RTS and CTS lines. To interface between the TS-480 transceiver and a PC, use a commercially available cable with a DB-9 fema
10、le connector at each end. Each connector pin must be connected to the same pin number at the other end (a straight cable). To control the transceiver from a PC, utilize the general purpose terminal program to send commands to the tranceiver. The transceiver responds the command accordingly. For exam
11、ple, the transceiver is placed into the transmit mode whenever the character string “TX;” is sent from the computer. The character string “TX;” is called a PC control command. You can further develop or create a script of the commands using a macro function of the terminal program. Kenwood also prov
12、ides the remote control program, ARCP-480 at our Web site. You can download the program for free and try it out on your PC. Access amateur.html and follow the instructions. 2 PC CONTROL COMMAND Alphabetical Commands A command consists of 2 alphabetical characters. You may use either lower or upper c
13、ase characters. The commands available for this transceiver are listed in the PC Control Command Tables from page 3. 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 as
14、signed to each parameter is also predetermined. Refer to the Computer Control Commands and the PC Control Command Tables to configure the appropriate parameters. When configuring parameters, be careful not to make the following mistakes. (correct parameter: “IS+1000”) IS1000;Not enough parameters sp
15、ecified (No direction given for the IF shift) IS+100;Not enough digits (Only three frequency digits given) IS+1000; Unnecessary characters between parameters IS+10000;Too many digits (Five frequency digits given) Note: If a particular parameter is not applicable to this transceiver, the parameter di
16、gits should be filled using any character except the ASCII control codes (00 to 1Fh) and the terminator (;). 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. Error Messages In
17、addition to the Answer command, the transceiver can send the following error messages. Error Message Reason for Error Command syntax was incorrect. Command was not executed due to the current status of the transceiver (even though the command syntax was correct). A communication error occurred such
18、as an overrun or framing error during a serial data transmission. Receive data was sent but processing was not completed. ?; E; O; Note: Occasionally this message may not appear due to microprocessor transients in the transceiver. COMPUTER CONTROL COMMANDS A computer control command is composed of a
19、n alphabetical command, various parameters, and the terminator that signals the end of the control command. EXAMPLE: Command to set VFO A to 7 MHz Alphabetical command ; Terminator 00007000000FA Parameters Commands can be classified as shown below: Input command (Input to the transceiver) Output com
20、mand (From the transceiver) Set command (Sets a particular condition) Read command (Reads an answer) Answer command (Transmits a condition) Computer control commands For example, note the following in the case of the FA command (Frequency of VFO A): To set the frequency to 7 MHz, the following comma
21、nd is sent from the computer to the transceiver: “FA00007000000;”(Set command) To read the frequency of VFO A, 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: “FA0000
22、7000000;”(Answer command) Note: Do not use the control characters 00 to 1Fh since they are either ignored or cause a “?” answer. Program execution may be delayed while turning the Tuning control rapidly. 3 PC CONTROL COMMAND CA . sutat srenutannetnal anretn iehtsdaerros teS: sretemaraP 1P URHTTA-XR:
