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 possible remote operation of your transceiver 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 • Computer equipped with an RS-232C serial port. • One straight cable This cable must have a 9-pin RS-232C female connector at one end, and at the other end a 9pin or a 25-pin RS-232C female connector that mates with the RS-232C port of your computer. • Transceiver control application To design your programs consult "APPENDIX" {page 70} for the necessary information. ■ Connections Connecting the transceiver to the computer is easy. See the diagram given in "CONNECTING PERIPHERAL EQUIPMENT" {page 60}. Note: Before connecting this transceiver to the computer, switch OFF the power to the transceiver and the computer. COMMUNICATION PARAMETERS In order to control the transceiver by computer, you must first choose the communication parameters. 1 On the computer, configure your transceiver control application for 8 data bits and no parity. 2 On the transceiver, select the appropriate transfer rate and number of stop bits via Menu No. 35. • 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. 12 OPERATOR CONVENIENCES Menu Setting 12 - 1 24 - 1 48 - 1 48 - 2 96 - 1 192 - 1 384 - 1 576 - 1 Transfer Rate (bps) 1200 2400 4800 4800 9600 19200 38400 57600 Stop Bits 1 1 1 2 1 1 1 1 USING A TRANSVERTER If you have a transverter that converts HF frequencies to VHF/UHF frequencies, and vice versa, you can use this HF transceiver as a VHF or UHF transceiver. For more information, consult the instruction manual that came with the transverter. 1 Connect the transverter to the ANT 1 or ANT 2 connector of this transceiver. 2 Select the operating frequency. • The transverter will use this frequency as the reference for converting frequencies. • Normally set 1 kHz and lower digits to 0 ("0.00" on the display). 3 Access Menu No. 40, and select 50 MHz, 144 MHz or 430 MHz, depending on which band you will use. The default is OFF. • Changing from the default (OFF) will automatically set the transmit power to approximately 5 W. • The transceiver displays a frequency down to the 10 Hz digit for 50 MHz, or down to the 100 Hz digit for 144 MHz and 430 MHz. Note: ◆ When using a transverter, not all the functions of this transceiver are available. ◆ When using the optional VS-3 unit, the selected VHF or UHF frequencies are not announced. 51
