MOD (K)/Ver. 2.00 Confidential CONTENTS 11 PORT FUNCTIONSThis section describes Input/ Output ports of the transceiver.1.1 8-pin Connector (Mic Connector)The 8-pin microphone connector is located on the front panel of the TK-7160/ TK-8160. Configuration data can bewritten into the transceiver or read from the transceiver by connecting the transceiver to a PC with KPG-99Dsoftware installed.Figure 1-1 8-pin ConnectorTable 1-1 Assigning Signals to 8-pin ConnectorPinNumberSignalNameInput/Output Items Description 1 Description 21 BLC OutputHigh/ Low LevelMaximum CurrentPull-up or NoneActive High or LowH = more than 4.2 VL = less than 0.8 V0.2 mA maximumPulled-up to 5 VActive Low-2 PSB Output Output VoltageMaximum CurrentSwitched or Unswitched13.6 V (Battery voltage)100 mA maximumSwitched battery output -3 GND - - - -4 PTT InputHigh/ Low LevelMaximum CurrentPull-upActive High or LowH = more than 4.2 VL = less than 0.8 V0.2 mA maximumPulled-up to 5 VActive LowRS232C level/RS232C polarityH = more than 5 VL = less than -5 VMaximum input ± 30 VBaud rate = 9600 bpsData = 8-bit, Parity = NoneStop = 25 ME - - MIC ground -6 MIC InputInput Level/ DeviationInput ImpedanceDC couplingFrequency Response5 mVrms ±5 mV at60% deviation600Ω loadDC coupled300 Hz to 3 kHz +6 dB/octave(EIA curve)-7 Hook InputHigh/ Low LevelMaximum Input VoltagePull-upActive High or LowH = more than 4.2 VL= less than 0.8 V±20 V maximumPulled-up to 5 VActive LowRS232C level/RS232C polarityH = more than 5 V,L = less than -5 VMaximum input ±30 VBaud rate = 9600 bpsData = 8-bit, Parity = NoneStop = 28 DM Input/OutputHigh/ Low LevelMaximum Current/Maximum Input VoltagePull-upActive High or LowH = more than 4.2 VL = less than 0.8 V±20 V maximumPulled-up to 5 VActive LowH = more than 4.2 VL = less than 0.8 V0.2 mA maximumPulled-up to 5 VActive Low
