15 OPERATOR CONVENIENCES

COMPUTER CONTROL

By connecting this transceiver to a computer, you can change the computer into an electronic console from which you can remotely control functions of the transceiver. This capability makes remote operation of your transceiver possible from across the room, from another room, or when coupled with other commercially available products and where lawful, from another city, state, or country via a telephone connection.

Note:

◆You can use the front panel controls while using computer control. Settings done from the front panel are effective immediately.

◆After the computer is disconnected or turned off, all values and settings on the front panel are restored.

SETTING UP

■Equipment Needed

•A PC equipped with an RS-232C serial port.

•One straight cable. This cable must have a 9-pin D-Sub RS-232C female connector at one end, and at the other end a 9-pin or a 25-pin D-Sub RS-232C female connector that mates with the RS-232C port of your computer.

•Transceiver control application.

To design your programs, consult “APPENDIX” for the necessary information.

■Connections

Connecting the transceiver to the computer is easy. See the diagram given in “CONNECTING PERIPHERAL EQUIPMENT” {page 93}.

Note: Before connecting this transceiver to the computer, switch OFF the power to both the transceiver and the computer.

COMMUNICATION PARAMETERS

In order to control the transceiver by computer, you must first choose the communication parameters.

1On the computer, configure your transceiver control application for 8 data bits, 1 stop bit and no parity.

2On the transceiver, select the same transfer rate and number of stop bits via Menu No. 56.

• The defaults are 9600 bps and 1 stop bit.

Note: To reliably use the 38400 or 57600 bps transfer rates, the RS-232C port of the computer must support these high-speed communications parameters.

REMOTE MICROPHONE CONTROLLER

If you have a DTMF microphone, you can use the microphone as a wired remote control unit as described below.

1Plug the DTMF microphone into the microphone connector of the transceiver.

2Press [MENU], then turn the MULTI/ CH control to access Menu No. 45D.

3Press [+] to select ON.

4Press [MENU] to store the setting and exit Menu mode.

The DTMF keys function as follows:

2The LOCK function is for the microphone keypad.

Note:

◆Microphone Remote does not function while transmitting.

◆You can use the DTMF Memory function {page 75} with the Microphone Remote function.

◆The Repeater function is available for K-type models only.

◆Normally, pressing [2] cycles through Tone, CTCSS, DCS, and OFF. However, if 1750 Hz is selected for Tone, pressing [2] will only transmit the 1750 Hz tone. To return to Tone/ CTCSS/ DCS mode, you must first deselect 1750 Hz for Tone.

◆Press [D] to enter FUNC mode, to use the 2nd function of the DTMF keys. Pressing [D] while in FUNC mode will exit FUNC mode.

◆[FUNC] on the transceiver works independently from the Microphone Remote [FUNC] key.
