21、. PC Mode3-1. PrefaceThe TK-3212/3217 transceivers are programmed using apersonal computer, a programming interface (KPG-22) andprogramming software (KPG-100D).The programming software can be used with an IBM PCor compatible. Figure 1 shows the setup of an IBM PC forprogramming.3-2. Connection proce

22、dure1. Connect the TK-3212/3217 to the personal computer withthe interface cable.2. When the POWER is switched on, user mode can beentered immediately. When the PC sends a command,the transceiver enters PC mode. In the PC mode,“PROGRAM“ is displayed on the LCD.When data is transmitting from the tran

23、sceiver, the redLED lights.When data is received by the transceiver, the green LEDlights.Notes: The data stored in the personal computer must match themodel type when it is written into the EEPROM. Change the TK-3212/3217 to PC mode, then attach theinterface cable.3-3. KPG-22 description(PC programm

24、ing interface cable: Option)The KPG-22 is required to interface the TK-3212/3217 withthe computer. It has a circuit in its D-subconnector (25-pin)case that converts the RS-232C logic level to the TTL level.The KPG-22 connects the SP/MIC connector of the TK-3212/3217 to the computers RS-232C serial p
