8112 OPERATOR CONVENIENCESCOMPUTER CONTROLBy connecting this transceiver to a computer, you canchange the computer into an electronic console fromwhich you can remotely control functions of thetransceiver. This capability makes remote operationof your transceiver possible from across the room,from another room, or when coupled with othercommercially available products and where lawful,from another city, state, or country via a telephoneconnection.Note:uYou can use the front panel controls while using computercontrol. Settings done from the front panel are effectiveimmediately.uAfter the computer is disconnected or turned off, all valuesand settings on the front panel are restored.SETTING UPn 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 oneend, and at the other end a 9-pin or a 25-pin D-Sub RS-232C female connector that mateswith the RS-232C port of your computer.• Transceiver control application.To design your programs, consult “APPENDIX”{page XX} for the necessary information.n ConnectionsConnecting the transceiver to the computer iseasy. See the diagram given in “CONNECTINGPERIPHERAL EQUIPMENT” {page XX}.Note: Before connecting this transceiver to the computer, switchOFF the power to the transceiver and the computer.COMMUNICATION PARAMETERSIn order to control the transceiver by computer, youmust first choose the communication parameters.1 On the computer, configure your transceivercontrol application for 8 data bits and no parity.2 On the transceiver, select the appropriate transferrate 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, theRS-232C port of the computer must support these high-speedcommunications parameters.REPEATER FUNCTION(K-type ONLY)This transceiver is capable of receiving signals onone band and retransmitting them on another band.For example, a signal received on the sub-receiver isretransmitted on the main transceiver. Similarly, asignal received on the main transceiver can beretransmitted on the sub-receiver’s frequency.You can use any available frequency on the maintransceiver or sub-receiver to receive and transmit.However, you cannot retransmit the receiving signalsoutside the amateur radio bands. You also must usea different antenna for transmitting and receiving. Forexample, if you receive a VHF signal on the sub-receiver, you can retransmit it using UHF on the maintransceiver. You cannot retransmit the signal usingVHF of the main transceiver.Note: For the repeater function to operate, the squelch levels ofthe main transceiver and sub-receiver must be adjusted so that nobackground noise can be heard.LOCKED-BAND REPEATERThe transceiver always uses the same band toreceive, and retransmits the received signals on theother band.1 Select a desired receive frequency on the sub-receiver.2 Press [MAIN] and select a desired transmitfrequency on the main transceiver.3 Adjust the squelch threshold level so that bothreceivers mute.4 Press [MENU], then turn the MULTI/ CH control toaccess Menu No. 61A.5 Select LOCKED, using [+].• “LOCK A” appears.Note: You can also reverse the receive and transmit bands, sothat you receive on the main transceiver and transmit on the sub-receiver’s frequency.CROSS-BAND REPEATERThe cross-band repeater is unlike the lock-bandrepeater in that both bands can be used to receivesignals. When a signal is received on one band, it isretransmitted on the other band. To activate thecross-band repeater, select CROSS in Menu No. 61Ain step 5.Note:uThe Repeater function has its own Time-out TImer which is set at3 minutes. This value cannot be changed.uAfter activating the Repeater function, you cannot access MenuNos. other than 61A and 61B.HANG TIME FOR REPEATER FUNCTIONIf necessary, you can cause this transceiver to remainin the transmit mode for 500 ms after signals drop.Access Menu No. 61B (Repeater TX Hold) and select“ON”.
