10 FT-8800R Operating ManualBASE STATION INSTALLATIONThe FT-8800R is ideal for base station use as well as in mobile installations. The FT-8800R is specifically designed to integrate into your station easily, using the informationto follow as a reference.AC Power SuppliesOperation of the FT-8800R from an AC line requires a power source capable of providingat least 15 Amps continuously at 13.8 Volts DC. The FP-1023 and FP-1030A AC PowerSupplies are available from your Yaesu dealer to satisfy these requirements. Other well-regulated power supplies may be used, as well, if they meet the above voltage and currentspecifications.Use the DC power cable supplied with your transceiver for making power connections tothe power supply. Connect the RED power cable lead to the POSITIVE (+) power supplyterminal, and connect the BLACK power cable lead to the NEGATIVE (–) power supplyterminal.Packet Radio Terminal Node Controller (TNC)The FT-8800R provides a convenient rear-panel DATA jack for easy connections to yourTNC. This connector is a standard mini-DIN connector. A pre-wired connector and cableassembly option, model CT-39A, is available from your local Yaesu dealer.The FT-8800R’s DATA jack connections are optimized for the data transmission and re-ception speed in use. In accordance with industry standards, the signal levels, impedances,and bandwidths are significantly different on 9600 bps as opposed to 1200 bps. If yourTNC does not provide multiple lines to accommodate such optimization, you may still beable to utilize your TNC, if it is designed for multiple-radio use, by connecting the TNC“Radio 1” port to the 1200 bps lines on the FT-8800R, and the “Radio 2” port to the 9600bps lines.The pin connections of the Data connector are shown below.INSTALLATIONPin123456LabelPKD(DATA IN)GNDPTTRX9600RX1200SQLNotePacket Data InputImpedance: 10 kΩ,Maximum Input Level: 40 mV p-p for 1200 bps2.0 Vp-p for 9600 bpsSignal GroundGound to Transmit9600 bps Packet Data OutputImpedance: 10 kΩ, Maximum Output: 500 mV p-p1200 bps Packet Data OutputImpedance: 10 kΩ, Maximum Output: 300 mV p-pSquelch ControlSquelch Open: +5 V, Squelch Close: 0 VCT-39A Wire ColorBrownRedOrangeYellowGreenBlueDATA Jack Pin Out
