Serial Driver Navigator 3.3 !FULL!


The MAX4820/MAX4821 8-channel relay drivers offer built-in kickback protection and drive +3.3V/+5V nonlatching or dual-coil-latching relays. These devices are especially useful when driving +3V relays. Each independent open-drain output features a 2Ω on-resistance and is guaranteed to sink 70mA (min) of load current. Both devices consume less than 50µA (max) quiescent current and have 1µA output off-leakage current.




Serial Driver Navigator 3.3



The cable is easiest way ever to connect to your microcontroller/Raspberry Pi/WiFi router serial console port. Inside the big USB plug is a USBSerial conversion chip and at the end of the 36" cable are four wire - red power, black ground, white RX into USB port, and green TX out of the USB port. The power pin provides the 5V @ 500mA direct from the USB port and the RX/TX pins are 3.3V level for interfacing with the most common 3.3V logic level chipsets.Because of the separated pin plugs, this cable is ideal for powering and connecting up to the debug/login console on the Raspberry Pi or BeagleBone Black. Connect the pins as shown to power the Pi or BBB and establish the RX/TX link.


Also handy for hacking WiFi routers to install alternate OS's, or nearly any other 3.3V logic serial port. This is easier to use than an FTDI cable in many cases because the wires are separated. Note that we call this a "TTL cable" (since that's what they're called) but technically it's CMOS logic.This cable is not good for Arduino re-programming such as a Boarduino, MENTA, Monochron, etc. because it does not have the DTR/RTS wire necessary for initiating the bootloader reboot sequence. For that we suggest an FTDI cable or FTDI friend.


The Red Hat Virtualization guest agents, tools, and drivers provide additional functionality for virtual machines, such as gracefully shutting down or rebooting virtual machines from the VM Portal and Administration Portal. The tools and agents also provide information for virtual machines, including:


The guest agents, tools and drivers are distributed as an ISO file that you can attach to virtual machines. This ISO file is packaged as an RPM file that you can install and upgrade from the Manager machine.


Paravirtualized HDD driver offers increased I/O performance over emulated devices like IDE by optimizing the coordination and communication between the virtual machine and the hypervisor. The driver complements the software implementation of the virtio-device used by the host to play the role of a hardware device.


Paravirtualized iSCSI HDD driver offers similar functionality to the virtio-block device, with some additional enhancements. In particular, this driver supports adding hundreds of devices, and names devices using the standard SCSI device naming scheme.


Virtio-serial provides support for multiple serial ports. The improved performance is used for fast communication between the virtual machine and the host that avoids network complications. This fast communication is required for the guest agents and for other features such as clipboard copy-paste between the virtual machine and the host and logging.


Worked perfectly, allowed me to reset a router directly, and fiddle with it. Love the documentation in the listing so I can figure it out even years after I bought it.Be sure to use the older drivers (before 3.4), don't use the Windows built in drivers which don't work on serial USB clone chips.If you have problems with Windows 10 auto updating your drivers look for wushowhide.diagcab


I've only used the USB to TTL functionality, but for 5 bucks that's far more than I need to give a solid 5 stars. I resuscitated a broken wifi router using some internal pins in that device, hooking this device to it and my computer. Everything worked well once I installed the driver. You can find the driver from the maker of the USB chip that's used. [...] and you probably don't want the enumeration one for this device, just the regular one.


successfully brought bricked router back to life.the tx rx lights are a bit misleading (didnt light up at successful connection, lit up when connected wrong).the driver can be installed automatically through device manager driver search.


SATA host adapters and devices communicate via a high-speed serial cable over two pairs of conductors. In contrast, parallel ATA (the redesignation for the legacy ATA specifications) uses a 16-bit wide data bus with many additional support and control signals, all operating at a much lower frequency. To ensure backward compatibility with legacy ATA software and applications, SATA uses the same basic ATA and ATAPI command sets as legacy ATA devices.


Windows device drivers that are labeled as SATA are often running in IDE emulation mode unless they explicitly state that they are AHCI mode, in RAID mode, or a mode provided by a proprietary driver and command set that allowed access to SATA's advanced features before AHCI became popular. Modern versions of Microsoft Windows, Mac OS X, FreeBSD, Linux with version 2.6.19 onward,[14] as well as Solaris and OpenSolaris, include support for AHCI, but earlier operating systems such as Windows XP do not. Even in those instances, a proprietary driver may have been created for a specific chipset, such as Intel's.[15]


Aimed at the consumer market, eSATA enters an external storage market served also by the USB and FireWire interfaces. The SATA interface has certain advantages. Most external hard-disk-drive cases with FireWire or USB interfaces use either PATA or SATA drives and "bridges" to translate between the drives' interfaces and the enclosures' external ports; this bridging incurs some inefficiency. Some single disks can transfer 157 MB/s during real use,[18] about four times the maximum transfer rate of USB 2.0 or FireWire 400 (IEEE 1394a) and almost twice as fast as the maximum transfer rate of FireWire 800. The S3200 FireWire 1394b specification reaches around 400 MB/s (3.2 Gbit/s), and USB 3.0 has a nominal speed of 5 Gbit/s. Some low-level drive features, such as S.M.A.R.T., may not operate through some USB[58] or FireWire or USB+FireWire bridges; eSATA does not suffer from these issues provided that the controller manufacturer (and its drivers) presents eSATA drives as ATA devices, rather than as SCSI devices, as has been common with Silicon Image, JMicron, and NVIDIA nForce drivers for Windows Vista. In those cases, SATA drives do not have low-level features accessible.


The physical layer defines SATA's electrical and physical characteristics (such as cable dimensions and parasitics, driver voltage level and receiver operating range), as well as the physical coding subsystem (bit-level encoding, device detection on the wire, and link initialization).


SATA physical coding uses a line encoding system known as 8b/10b encoding. This scheme serves multiple functions required to sustain a differential serial link. First, the stream contains necessary synchronization information that allows the SATA host/drive to extract clocking. The 8b/10b encoded sequence embeds periodic edge transitions to allow the receiver to achieve bit-alignment without the use of a separately transmitted reference clock waveform. The sequence also maintains a neutral (DC-balanced) bitstream, which lets transmit drivers and receiver inputs be AC-coupled. Generally, the actual SATA signalling is half-duplex, meaning that it can only read or write data at any one time.


Layer number three in the serial ATA specification is the transport layer. This layer has the responsibility of acting on the frames and transmitting/receiving the frames in an appropriate sequence. The transport layer handles the assembly and disassembly of FIS structures, which includes, for example, extracting content from register FISs into the task-file and informing the command layer. In an abstract fashion, the transport layer is responsible for creating and encoding FIS structures requested by the command layer, and removing those structures when the frames are received.


Many motherboards offer a "Legacy Mode" option, which makes SATA drives appear to the OS like PATA drives on a standard controller. This Legacy Mode eases OS installation by not requiring that a specific driver be loaded during setup, but sacrifices support for some (vendor specific) features of SATA. Legacy Mode often if not always disables some of the boards' PATA or SATA ports, since the standard PATA controller interface supports only four drives. (Often, which ports are disabled is configurable.)


A- Used to verify whether there is any compiling mistakes or not.B- Used to upload the sketch to your Arduino board.C- Used to create shortcut window of a new sketch.D- Used to directly open an example sketch.E- Used to save the sketch.F- Used to send the serial data received from board to the serial monitor.


IMPORTANT: If upgrading, be sure to unplug the HASP key before uninstalling the previous version of SpectraMagic NX and the previous HASP driver. Attempting to uninstall with the HASP key plugged in may prevent uninstall from being performed properly.


If you trying to install a USB device class driver included in Windows, you do not need to download the driver. They are installed automatically. If they are not installed automatically, contact the device manufacturer. For the list of USB device class driver included in Windows, see USB device class drivers included in Windows.


Starting in Windows 10, Usbser.inf was added to the %Systemroot%\INF directory, which loads Usbser.sys as the functional device object (FDO) in the device stack. If your device belongs to the communications and CDC control device class, Usbser.sys is loaded automatically. You do not need to write your own INF to reference the driver. The driver is loaded based on a compatible ID match similar to other USB device class drivers included in Windows.


Microsoft encourages you to use in-box drivers whenever possible. On mobile editions of Windows, such as Windows 10 Mobile, only drivers that are part of the operating system are loaded. Unlike desktop editions, it is not possible to load a driver through an external driver package. With the new in-box INF, Usbser.sys is automatically loaded if a USB-to-serial device is detected on the mobile device.
