This listing is for a single BlueMax49ers, aftermarket, 3 ft, PMKN4115B Motorola Network Adapter, drivers, programming software, and installation technical support for the Motorola XPR3300e model with a 3-year replacement warranty.

My call sign is KJ6ZWL.  This business is our passion!  We have been in business since 2013 and have sold over 75,000 cables.  Our BlueMax46ers cables work.  We provide same-day shipping on orders received before 3 p.m. Pacific Time from San Jose, California.  Here are more reasons you will want to buy this cable from BlueMax49ers.

Our customers' first problem is finding the correct cable for their radio, scanner, etc.  We stock over one hundred different programming cables proven to work with more than 5,000 radios, scanners, and other devices.  All cables come with a 3-year replacement warranty.  We use over two hundred radios to test our cables to ensure they work!  If you cannot find a BlueMax49ers cable for your model on eBay, contact us.  Contact us if you want custom-length cables.

The second problem is finding out what programming software they will need for their model and if it will work on the computer’s operating system version that they have.   It is the programming software that limits the operating systems that you will need, not the cable.  More than half of the software in our library is not compatible with Windows 10 or 11.  Our BlueMax46ers Software Advisor recommends operating systems compatibility for all our software titles.

Radio Programming Software Available on Request after Purchase

The third problem is finding the latest programming software to download.   If available, we have 1,000 different programming software titles, wide-band and narrow-band, in our programming software library.  In most cases, we can share download links to the software for a customer who buys our cable.  We do not sell software.  After you buy a cable on eBay, you must send us an email or message requesting the download link.  

The fourth problem is getting technical support when you have a problem.  All our cables come with installation instructions, email address, and cell phone number.  We stand behind everything we sell and promise to do our best to troubleshoot any problem you experience.

Please check this listing's photos for a close-up of the connector to ensure that this cable matches the physical characteristics of your radio's port before ordering this cable.  Most radios use the microphone jack as the programming port, but some have a separate data port for programming and PC to internal TNC interface.  It is essential to know that programming cables use fewer signal pins than a microphone, so the pinouts are typically more straightforward than your microphone cable.

Q. Where can I find the device drivers for my FTDI or Prolific cable?

A. Typically, the operating system will install the drivers when you plug the cable into the computer.  Finding and installing the device drivers automatically takes 4 to 6 minutes. The cable comes with installation instructions on how to download and install any drivers that you need.

Q. How can I tell if the USB serial cable I buy uses the Prolific or FTDI USB to serial converter chipset?

A. If it does not say FTDI in the listing title, it will use the Prolific chipset.  True USB cables do not use USB to serial chipsets.

Q. What is the difference between FTDI and Prolific USB serial cables other than the FTDI are more expensive?

A. Our FTDI cables have LED activity lights and are typically 6 feet in length.  Contact us if you want custom-length FTDI cables.  Our Prolific cables do not have activity lights and are 3 feet long.

Q. Do your cables work with RTSystems software?

A. Yes, beginning with Rev 5.0 of RTSystems software now works with cables from other vendors including BlueMax49ers.
