The ONLY interfaces on eBay to have been accepted and approved by the deveopers the Ham Radio Deluxe software.
No point paying more for many "lesser" eBay copies when the best simply costs less !
For whatever CAT/Logging software you use.

Using the ZLP Electronics eBay CT62

[1] Plug the interface 9 pin D type connector into you comport.
You need to know the correct comport number as you will need to set this in your software.
If you don't have a comport these interfaces will work with a USB to serial interface cable and often have better noise performance than an equivalent USB interface when used this way. Note: Many cheap (and some not so cheap) USB to serial cables will not function correctly, you should ensure that your USB to serial cable actually conforms to RS232 specs by measuring voltage at RTS and DTR pins (6v minimum when active).

[2] Plug the 8 pin mini din CAT connector into the radios 8 pin CAT/LINEAR/TUNER socket (not the 6 pin data socket).
You WILL damage one or more pins in the din plug if you get this wrong.
Damage caused this way is obvious as one or more pins will be pushed back or broken, this is not covered by your warranty.

[3] Configure your software so as to raise the comports "DTR" line.
The interface is powered via the comports DTR line.

[4] Configure the software to the baud rate as set on the radio (consult your manual).
Software and radio baud rates MUST match.

[5] Configure your radio so that the multipurpose CAT/LINEAR/TUNER socket is to be used for CAT (consult your manual).
Some radios require the multipurpose socket to be set for CAT via the radios menu system.

Click "connect" or whatever your CAT / Logging software requires to connect to the radio.
If you are using a USB to serial interface cable / adaptor, then it MUST be plugged in BEFORE starting your software.
I DO NOT RECOMMEND AUTO-DETECT, THIS CAN GIVE MISLEADING RESULTS.

I will repair this damage but a charge will apply.
This can be normally be repaired easily if done carefully.
