Depending on the product, you can find your serial number: On the surface of your product. In iTunes, if your product syncs with iTunes. On a Mac, by choosing About This Mac from the Apple menu.; On an iPhone, iPad, iPod touch, iPod, or Apple Watch, in Settings > General > About. I just received a signed driver by Winchiphead for their USB Serial bridge CH340. Now it should be possible to use Arduino’s equipped with that without any problems under Mac OS 10.9 to mac.

Phase Phase is used to describe the two main types of alternating current (AC) electric power produced by a utility, generator or UPS system. Single-phase power includes a single AC waveform, making single-phase equipment ideal for lower power density applications with per-rack power consumption levels up to approximately 2.8kVA (120V), 5kVA (208V) or 7.4kVA (230V). Three-phase power includes 3 AC waveforms, making 3-phase equipment better suited for intermediate and high-capacity applications with per-rack power consumption levels that surpass the practical energy limits of single-phase equipment.

PDU Type Basic PDUs All PDUs including Basic PDUs provide reliable rack-mount power distribution for data centers, server rooms, and network wiring closets. Metered PDUs Metered PDUs monitor load levels to avoid potential overloads via a LCD display. Monitored PDUs Monitored PDUs remotely monitor voltage, frequency, and load levels via a built-in network connection. Switched PDUs Switched PDUs can securely control individual outlets remotely to enable the rebooting of unresponsive equipment to minimize downtime. Auto Transfer Switch (ATS) PDUs ATS PDUs provide redundant power to connected equipment with separate primary and secondary power sources. Hot-Swap PDUs Hot-Swap PDUs have dual input power cables to enable live-replacement of select UPS systems with no power interruption to connected equipment.

I just received a signed driver by Winchiphead for their USB Serial bridge CH340. Now it should be possible to use Arduino’s equipped with that without any problems under Mac OS 10.9 to mac OS 10.13 (High Sierra). For High Sierra you must allow the driver to load in the Security & Privacy Settings you will be asked for it once you plug in a device with this serial chip, Thanks to Robin for this info. Until it is available on the Winchiphead Website you can download the driver package here (Updated ): Little hint that Altais posted in the comments if it does not work correctly. You can try copying the usbserial kext to the folder /System/Library/Extensions.

Easiest way is the terminal here: sudo cp /Library/Extensions/usbserial.kext /System/Library/Extensions If you have problems with the driver using the latest OSX High Sierra please refer to the KB Article: Thanks to Thomas B. For this hint.

I have not tried this by myself. I tried this for hours but I can’t get it to work. The driver is correctly installed and the kext is loaded. Dmesg output suggests that the driver is at least doing something, once I plug a board in: wch_usb start. 1 0 wch_usb: configDMM – find the config interface numbers However, it hangs at that point. No serial device. I got it working once, but after that no luck. Idledev anticipated changes for mac.

It’s very sporadic. Even the wch_usb_start output is not shown every time. In fact, the usb id of the device sometimes jumps in the system monitor. Sometimes it’s even not there at all. So you have to be lucky for the usb subsystem to see it _and_ for the driver to initialize it correctly, which almost never works. If I try plugging and unplugging the device long enough, dmesg comes up with a „permanent usb enumeration error“, after which the driver is completely silent and I have to reboot. I tried multiple boards, all with the same result.

On a Windows box however, they all work flawlessly. Bottom line: At least on some mac hardware this chip is unusable. I am using arduino nano n el capitan. After installing the driver, el capitan manage to recognise the nano at /dev/cu.wchusbserial1420 but when i try to upload the sketch i got: Arduino: 1.6.11 (Mac OS X), Board: „Arduino Nano, ATmega328“ Sketch uses 1,042 bytes (3%) of program storage space. Maximum is 30,720 bytes.

Global variables use 9 bytes (0%) of dynamic memory, leaving 2,039 bytes for local variables. Maximum is 2,048 bytes. It worked perfectly with my Prusa 3D printer using Arduino clone board under el Capitan. However with Sierra I get a kernel panic like this one right after inserting usb cable and it keeps rebooting will the usb cable plugged in. Asus m51vr drivers for mac. I tried to re-install the driver (had to ) and actually cannot make it shown with ls /dev/tty* anymore but it sits perfectly under cd /Library/Extensions/ Look like it cause OS to panic when OS attempts to load it. What could possibly can be done and how can I help to figure out the cause of the problem?
