3.6.3 Connections PTC - YAESU
Some YAESU’s like the FT890 or FT990 use a 6 pin DIN socket for remote control:
Signal PTC Color YAESU
TxD PIN 9 pink PIN 3
RxD PIN 1 violet PIN 2
GND PIN 13 orange PIN 1
Table 15: YAESU FT 890/990
Older transceivers like the FT757 supports serial input only. In this case the PTC-IIpro adjusts
the frequency but could not read it out.
Signal PTC Color YAESU
TxD PIN 9 pink PIN 3
GND PIN 13 orange PIN 1
Table 16: YAESU FT 757
Newer YAESU’s (FT-920, FT847, FT-1000MP) use a 9 pin SUB-D connector and V24 levels
for control, intended for connection to a COM port of a PC. Also these radios can be controlled
by the PTC-IIpro. Solder a 9 pin connector to the attached cable as shown in the table 16.
Signal PTC Color YAESU
TxD PIN 3 yellow PIN 3
RxD PIN 8 red PIN 2
GND PIN 13 orange PIN 5
This cable is available completely assembled.
Refer to chapter 5 on page 52.
Table 17: YAESU V24
Portable transceivers like the FT-100, FT-817 or FT-897 use a 8 pin Mini-DIN connection:
Signal PTC Color YAESU
TxD PIN 1 violet PIN 4
RxD PIN 9 pink PIN 5
GND PIN 13 orange PIN 3
This cable is available completely assembled.
Refer to chapter 5 on page 52.

Do not forget to set the exact YAESU transceiver type using the command YType. Refer to
chapter TRX in the main manual.
