I use several types of USB to Serial converters on Mac OS X, mostly for playing with Jeenode / Arduino hardware or connecting my HAM radio devices.
One of these devices, a Kenwood TH-D72, has a built-in Silicon Labs CP210x chip. The Mac OS X driver supplied by Silicon Labs is not very stable; it has caused my Mac to crash several times already. Uninstalling this driver is not as easy as uninstalling other applications on Mac; normally, you just drag the app into the trash – done. However, these drivers are supplied in “pkg” (package) format. Uninstalling software packages is [...]

Serial ports, a.k.a. RS232 ports, are no longer available on new computers and laptops. Many devices still use RS232 for communication (network equipment, data acquisition boards etc.).
There are several USB adapters that provide a “Virtual COM Port” using a special “USBtoUART” or “USBtoSerial” chip. Conversion cables containing these chips can be found online – but the documentation rarely specifies which chip is used! The Prolific PL-2303 chip is very popular, but a number of other chips can be found. Some chips are supported by the OS, others need a special driver.

Vandaag een bliksembezoek gebracht aan de DNAT in Bad Bentheim. Het weer wilde niet meewerken, erg jammer.
Toch nog even op de beurs rongelopen en een paar leuke dingetjes op de kop getikt, waaronder twee magneetvoet-antennes: een Diamond MR77B en een Nagoya UT-106UV, beiden voor 2m en 70cm.
De Diamond is geschikt voor serieus gebruik; de Nagoya een stuk minder. Op de terugreis bewees de Nagoya dat Duitse snelwegen geen probleem hoeven te zijn voor de kleine magneetvoet
Ik heb ook nog even gesproken met Jan, de man achter de JWX Windowclasp antenne. Die antenne lijkt me ideaal voor mobiel gebruik [...]

A quick note on installing the Prolific PL-2303 USB-to-Serial driver under Windows 7.
My Puxing PX-777 Plus radios can be programmed using a USB Programming Cable. The “6-in-1″ programming software is only available for Windows. On my Mac, I run a virtual Windows 7 installation under VMware Fusion.
PL-2303 USB-to-Serial driver
I tried the supplied drivers from 409shop for Puxing; I also tried latest drivers from the Prolific website (PL2303_Prolific_DriverInstaller_v130.zip). These appear to install correctly, but upon inserting the USB cable Windows 7 returns an error “The Device Cannot Start (Code 10)” and claims the driver was not installed. Re-installation did not help.
After [...]

By default, the Puxing PX-777 radio starts in “Frequency Mode”. Sometimes it’s nice to see a name instead of the frequency. You can enable channel names if the radio is running in “Channel Mode”.
I programmed these channel names on a PC using the 6-in-1 software with a USB programming cable.
To toggle between “Frequency Mode” and “Channel Mode”, press and hold the “enter” key while switching on the radio. The radio now displays channel numbers like “CH-001″. This setting will be remembered until you change it.
Go to Menu 15 (Name), press “enter”, use the encoder to select “On” and press “enter” [...]
