Kenwood Th D72a Usb Serial Driver For Mac

Updated 24 June 2014USB-to-Serial Adapter Cables for Ham Applications For over 15 years now, Microsoft has been attempting toforce the phase out of classic RS-232 serial ports on PCs. (They actuallycoined the term 'Legacy-Free PC' to refer to new designs without serial orparallel ports.)However, many, many amateur radio applications still require RS-232 serial'COM' ports. Some of the many uses are: packet TNCs, radio memory programming,connecting GPS receivers, sound-card-interface transmit keying (PTT), rotatorcontrols for satellite tracking, and remote control & logging applications on HFtransceivers.Virtually no new PCs available at retail for the last 5 yearshave serial ports. Serial ports are still available on some expensivespecialized machines intended for non-consumer use, such as Panasonic Toughbooksand certain vertical-market Dells. The majority of 'civilian' users havebeen forced to resort to the notorious and frequently problematic serialUSBconverter cables a.k.a. 'dongles' if serial ports are required.These cables are not just pieces of wire with a different kind of plug oneach end.

Many of the sites listed below give access to the tens of thousands of books (plus movies, songs, and cartoons) available under this act. Downloads should be free and without retribution under U.S. Barbara mellix bio. Because of an amendment to that act, works published between 1923 and 1977 can enter the public domain 95 years after their creation. A huge quantity of books previously unavailable to the public was released starting in 2019 thanks to the Sonny Bono Copyright Term Extension Act of 1998.

I just got my Kenwood TH-D72A radio. I was going through the manual section on buttons and pressed PF. WorldwideDX Radio Forum. I haven't been able to get the software USB to Serial driver to load so I have only been able to play with the radio and the manual, that lacks a little. #3 BladerunnerKC, Jan 16, 2012.

They actually contain an active microcontroller device,. One of ahalf-dozen or so specialized serial/USB conversion chips, provided by one of 4or 5 manufacturers is inside the molded DB9 plug, powered from the 5 VDCavailable from the USB end. In turn, this chip is dependent on a software driverinstalled into the operating system to function. Normally, such drivers create avirtual COM port that serial-using applications can then use like an actualphysical serial port.The quality and stability of the drivers varies wildly from chip vendor tochip vendor. Some versions of these drivers emulate a physical serial portfar more faithfully than others. Some drivers will work with certainversions of Windows but not others.

Or only certain applications will recognizethe virtual COM port created by the driver.Further, users may be dealing with the headaches of serialUSB conversionwithout even realizing it. So-called USB GPSs, USB interfaces ontransceivers, 'USB' versions of TNCs and other devices are actually serialinternally. Exactly the same kind of serialUSB chip as in thestand-alone cables, is used to offer a 'USB' version of the device. Theonly difference is that the serialUSB conversion takes place inside thedevice rather than in a cable between the device and the computer. Many of theseso-called USB devices use exactly the same chips and drivers asthe stand-alone serialUSB cables.The give-away is that the applications on the PC, that use these devices,still require you to choose a COM port rather than referring to the USB devicenatively by name.For example, the 'USB' interface on the Kenwood TH-D72 APRS handheld isactually the serial interface of it's predecessor TH-D7 with a serialUSBchip added internally. The 'driver' provided for the PC reconstitutes theserial COM port of it's predecessor for the benefit of APRS and packet programsthat only think in terms of classic RS-232 COM ports.

The ultimateirony is that the radio-specific memory programming utility for this 'USB' radiorequires you to choose and access a virtual COM port, instead of nativelyaccessing the USB port.A second example. The USB-based 'GPS Locator' bundled with some versions ofMicrosoft Streets & Trips, MapPoint & Autoroute, the Globalsat BU-353 low-costpuck GPS, the Pharos iGPS-180, many Holux GM-series GPSs, and countless otherGPS devices are all based on the Prolific PL-2303 chip. They use exactly thesame driver for the Prolific PL-2303 chip that you find bundled with countlesslow-cost serialUSB dongles. The only difference isthat the device description (that shows in the Windows Device Manager) has beenchanged from the generic 'USB-serial Bridge' to 'Microsoft GPS Locator' orsomething similar.The Major Problems with theProlific PL-2303 Chip and it's DriversOne of the most widely-used chips in low-cost serialUSBdongles and 'USB' GPS devices is the Prolific Technology PL-2303.It's drivers have been released in countless versions for every flavor ofWindows beginning with Windows 95/98 up to and including the latest Windows8-64.

This device has also been supported on various flavors of Linux, theMac OS and even on Android smart phones. Prolific's English-language homepage in Taiwan is here:This device and it's associated drivers worked reasonably welluntil manufacturers on the Chinese mainland began counterfeiting Prolific chipsseveral years ago, and started pirating Prolific's drivers. Prolificresponded by placing a kind of DRM (Digital Rights Management) into it'sdrivers. The driver somehow tests the chip for 'authenticity' and refuses to runif the chip is deemed a fake. This yields the dreaded yellow triangle withexclamation mark in Windows, along with 'Error Code 10 - Failed to installdriver'.The fake 2303 chips have managed to infiltrate the world-wideelectronics-manufacturing supply chain, and randomly appear in hundreds ofproducts from dozens of legitimate manufacturers.

Many manufacturers ofGPS devices and serialUSB dongles have taken to bundling older versions ofthe Prolific driver (that lack the 'genuine check' routine) with their productsto work around this headache. However these older driversoften won't work with newer variants of the PL-2303 chip. Since manydifferent devices use the PL-2303 chip, you experience some version of thefollowing scenario:.You install a device with an older version of the Prolificdriver. Every thing works just fine.You then acquire and install another device that happens tohave a newer version of the chip in it. Windows 'Plug-N-Pray' thendiscovers that a driver for this chip is already on your system the first timeyou connect the new device, and 'automagically' enables a second copy of theexisting driver for the new device.

However, you get the yellow triangle andthe dreaded 'Error 10'.The new device doesn't work with the old flavor of the driver.The user downloads and installs the 'latest and greatest' version of thedriver from the Prolific website.Now the new device works, but the older device (with thecounterfeit chip in it) stops working.Or everything worked great on your old Windows XP computer, butnow nothing (or only some devices) work(s) on the new Windows 7-64 computerSome manufacturers bundle new driver versions that have beenhacked to disable the 'genuine check'. These work on 32-bit versions ofWindows XP and Win 7. However, they fail miserably on Windows 7 & 8 64-biteditions. This is because the 64-bit editions of these OSes requiredrivers to be tested, certified and blessed by Microsoft with a 'digitalsignature' before they will install. The 'hacked' versions of the driverfails the digital signing validation and won't install on 64-bit systems.Or you can go through a byzantine procedure involving registryhacks and reboots into 'Safe mode' that defeats driver signing tests in Win7-64.

(There is a 'Test' mode, intended for developers of new drivers, that will defeat thedriver signing test and allow the installation of 'unofficial' drivers fortesting and debugging.)After the 'test mode' tweaks, the hacked driver works for a while. Until theever-helpful Windows Update decides to automatically download and install thelatest official Microsoft 'signed' version of the PL2303driver that DOES include the 'genuine' check in it.There are really only two ways to get around this mess.Throw out all older Prolific-based devices and cables thatfail to run on the current DRMed verion of the driver, and replace them withnew ones that do work with the latest version.Avoid PL-2303-based devices entirely.

Otherchipsets from FTDI, Cypress Semiconductor and Silicon Labs don't have these problems.(Silicon Labs chips are used by the built-in serial-to-USB conversions in theKenwood TH-D7 and some Yaesu products.)This May Be The Ultimate DongleFor Ham Applications!SerialUSB interfaces based on the FTDI chip set do notsuffer from the numerous problematic driver issues that plague the Prolificchipset. There are numerous serialUSB devices based on the FTDIchipset, but the one pictured below, a 'Gearmo FTDI2X' is exceptionally usefulfor ham applications.You get two DB9 serial ports from a single USBconnection.

For APRS applications, this means one port for the TNC and one forthe GPS receiver. The two serial-side cables are 1 meter (approx 39') long,while the USB-side cable is about.4 meter (approx 17') long.The COM port number assigned to each DB9 'sticks' and remainsthe same no matter what USB port you plug the cable into.(Prolific-based devices randomly acquire a different COM everytime you plug the device into a different USB port, or via a hub instead ofdirectly.).The 'goiter' in the middle of the cable is made of a smokytranslucent plastic that allows 3 LED indicators for TXD, RXD and POWER toshow through. These indicators can be quite useful for determining ifdevices on the serial side(s) are actually putting out data.The cable in the picture has two serial ports, but Gearmooffers similar cables with up to FOUR serial ports.The installer for the FTDI driver is a single downloadable.EXE that contains drivers for every flavor of Windows 32 or 64 bit from Win98to Windows 8. The appropriate version is automatically extracted and installedwhen you run the same setup on any flavor of Windows. I have installed thisdevice and it's associated drivers on two Win7-64 machines and 5 WinXPmachines of varying vintages.

The longest time from starting SETUP.exeto plugging in a functioning device was about 20 seconds. And it workedon the FIRST TRY each time!.The FTDI driver produces a far more comprehensive screen ofoptions when you drill down through the Device Manager 'Port Settings,Advanced' dialog. Instead of the generic serial port dialog that only lets youset COM number and the size of the TX and RX buffers, you get a huge menu ofoptions. One of these is being able to toggle 'Serial Enumerator' ON or OFF.Typical Serial Port Configuration DialogFTDI Expanded Serial Options.Serial enumeration means Window 'Plug-N-Pray' tries to look through the serialport to identify the device attached to the port. In the case of portsconnected to live NMEA GPS devices spewing out data once a second, this alwaysresults in Windows falsely identifying the device as a 'Microsoft BallpointMouse', an ancient clamp-on serial trackball for early laptops.

The mousecursor then goes insane skipping all over the screen and randomly clicking onthings as it interprets the NMEA data stream as mouse movements.See details on this headache.Disabling serial enumeration completely stops this problem.The FTDI chipset is capable of operating at serial speeds inexcess of 900K/second (!), and will operate with 5, 6,7 or 8 databits/character. The 5-bit mode, which is not supported by most dongles,makes it usable for classic 5-bit/char Baudot RTTY operation.The device and it's drivers are stable and rock-solid. Iroad-tested it for hundreds of miles on the way to and from the 2013 DaytonHamvention, using both my 32-bit WinXP Panasonic Toughbook and my new Win7-64Acer 756 netbook , withabsolutely no problems.This product is made by 'Gearmo'. Their website ishere:Note that they offer a variety of FTDI-based dongles in versionswith 1, 2 or 4 serial ports from one USB port. They sell through the website.I got mine for USD $10 less from this Amazon page:Update 22 May 2013: Apparently the writeup onthis page has already caused a sellout of the limited supply of the Gearmocables at the cheap price this vendor had! Hope that they restock.A version with a single serial port on a short (less than 1foot) pigtail is here:Googling for 'ftdi usb to serial' yields quite a few otherdongles based on this superior chipset, which should have about the samecapabilities.From NewEggAnother (single port) Gearmo from AmazonEven Walmart.

6-Pin Mini-DIN 'Packet'/'Data' ConnectorThe 6-Pin MIniDIN jack is a standard used by all the Japanese ham equipment manufacturers. Many current all-band all-mode and VHF/UHF transceivers are equipped with this jack. This jack is variously called 'data', 'packet', 'auxiliary', etc, but actually there are no data connections on this connector. This IS NOT a serial data or RTTY direct FSK port. Only various forms of receive and transmit audio are present. The connector provides receive audio output at a fixed level of about 100-300mV, transmit audio input at about the same level, transmit PTT keying, receiver squelch status (COR), and ground/common.

The normal RX audio line, which is live on both FM and SSB in multimode transceivers, is sometimes labeled '1200 baud packet'. However, the output is just standard receiver audio (deemphasized on FM) similar to what comes out the radio's speaker.

Output level is fixed, unaffected by the volume control. The audio at this point is suitable for any voice-frequency-band.
