based on the Prolific PL2303 where you get the message 'cannot start
code 10' shown in Device Manager
Prolific do not support their early PL2303 USB chips on operating
systems after Windows 7. You get a message 'cannot start code 10' in
Device Manager when using these chips on Windows 8 and above. If you
have an older chip in your programming cable and get this message see
this link for how to get an older driver installed.

|The VX-8 and
VX-8D connection is a
proprietary 7-pin design. The Yaesu CT-134 clone cable and the CT-M11
external headset connection cable for the FTM-10R both have the correct
plug attached. In conjunction with a
FTDI TTL-232R-3V3 cable it is easy to make up a suitable lead. See
the 'Connection to the radio' section of the
FTBVX8 Help file
for more details and pictures. The picture on the right is a cable made
|The VX-8G data cable is a simple
wire connection at RS232 levels - no level converter. Then use a
USB/serial adapter if you do not have a serial port on your PC.
||The VX-8G operating manual has details of
the cable in the Appendix, CT-143 Cable Connections. In summary they
are: stereo tip to DB9 pin 2 (radio => PC), stereo ring to DB9 pin 3 (PC
=> radio), stereo sleeve to DB9 pin 5 (GND).
A DIY adapter cable to enable
my 6-pin mini-din FT-7800 cable to be used on my FT-60, VX-3, VX-110 and VX-150. Uses half a
CT-27 clone cable and the mouse port off a dead motherboard.

packet socket found on the FT-7800, FT-8800 and FT-8900.
For 2-wire programming purposes
use pin 3 PTT for data and pin 2 GND for ground.

article by G4TIC. This will work with radios that use a 2-wire
interface e.g. VX-150, VX-170, VX-177, VX-6, FT-1802, FT-1807, FT-2800,
FT-7800, FT-8800, FT-8900.
I have built this circuit myself and it works
fine. A picture of my board is on the right. Because they were already
available I used 1N4002 diodes instead of 1N914 and PN2222A
transistors instead of 2N2222.
Roger Maeder has sent me some files to help with creating a PCB for the
G4TIC interface. See opposite for a) a zip file of the files; b) a
