MSK Detection Input Level Adjustment (Same as for the TK-*80 series and TK-*60G series) Set the input voltage at pin 2 of the CODEC IC (IC20) of the KDS-100 to 1000mVp-p. 1) Modulate SSG with a modulation frequency 1200Hz (or 1000Hz) (Wide: 3kHz, Narrow: 1.5kHz) and input it to the transc

21、eiver. 2) Measure the KDS-100 DI voltage (DI: CN5 pin 3, trans- ceiver detection output voltage) with a VTVM. 3) Set the “Input Level” DIGIT value according to the fol- lowing conversion table on the “MSK” screen in “Test Mode” so that the measured voltage (mVrms) is the CODEC IC input voltage (1000

22、mV). 4) When you click on “OK” on the PC screen, the adjust- ment value is written into the KDS-100 memory. 6 KDS-100 1.Power Supply Circuit The KDS-100 power supply circuit uses a dedicated regu- lator IC for each circuit application so that the circuits do not interfere with each other.

It communicates with the DSP through an external data bus.

29、Since the CPU operates on 5V and the DSP and flash ROM (IC13) operate on 3V, the address data bus is con- nected through a 5V-3V level conversion IC (IC11, 11, 36, 37).

30、time clock The message transmission/reception time is controlled by the dedicated real-time clock IC (IC2). When the power supply is OFF, it is backed up by an in- ternal secondary lithium battery (BA1). System reset, RAM, real-time clock backup The power supply voltage monitor IC (IC1) monitors pow

31、er supply voltage (8V). If the voltage falls, the PFO port goes “LOW” level, the CPU PFint (INT0) port also goes “LOW” level, and the CPU stops. If the 5V power supply voltage (for the CPU, S-RAM, and real-time clock IC) drops, the backup power supply for the S-RAM (IC12) and real-time clock IC (IC2

32、) is switched to the secondary lithium battery (BA1). When the power supply restores to its normal voltage, the IC1 PF0 port goes “H” level and the CPU PFint (INT0) port also goes “H” level. In addition, the RESET signal from IC1 is sent to the CPU RESET port to initialize and start the CPU. CEOUT i

If the VCC is lower than the threshold, CEOUT goes “High”. (Fig- ure 7) Note: The backup lithium battery (BA1) is fully charged from the empty state
