Each USB controller on a computer can use up to 127 devices making it almost limitless. To get to 127 devices you do need to use USB hubs. Remember that each USB hub you use counts as a USB device. Back To Questions

The USB specification allows for up to 127 USB peripheral devices to be used in a single system. Quatech 1-8 port adapters require one USB port, 16-port adapters require two USB ports. Thus, by using a series of hubs, up to 127 Quatech 8-port adapters or 63 16-port adapters can be used. This means that (using 127 eight port adapters) a single USB port can be used to connect 1016 serial devices.

Yes. There are USB receipt printers, cash drawers and scanners available. If you don't see an interface type you are interested in, please call us.

Hardware: You need a USB port in your computer. Most computers build since 1998 have at least two built in USB connectors. You can also get PCI and CardBus USB adapters for older computers. Software: For Wintel computers, you need Windows98, WindowsME, Windows2000, WindowsXP, or a recent version of Linux. There is limited USB support on Windows95 OSR 2.1, and none on WindowsNT. For USB support on Apple Macintosh computers you need MacOS 8.1 or later.

This list is by no means exhaustive but attempts to cover as many USB devices as possible that are known to work under Solaris. Also, in addition to many new devices being introduced into the market each day, many may have undergone revisions or updates to their firmware or hardware even though they may be listed with the same model number or are no longer available.

Refer to System Administration Guide: Basic Administration (for Solaris 9), Devices and File Systems (for Solaris 10 and Express release) For the Solaris 8 and Solaris 9 OS releases, the latest updates will install the USBA1.0 kernel interfaces as part of a Dual Framework. The Dual Framework consists of two USB frameworks: the newer USBA 1.0 framework which supports USB 2.0 devices, and the original framework of the OS release.

This depends. If you have Windows 95 ORS2 with the appropriate drivers for USB installed some USB controllers will work. Before making the purchase you should verify that your USB ports function properly and the device supports Windows 95.

Not only will it not work, you may damage your device. In order for a device to work with USB it must be compatible and have appropriate drivers. Some early releases of the Freestyle Pro and Precision Pro were not USB compatible; if it did not come with an adapter you are out of luck.

You can connect up to 15 devices to one RTU, in any combination of digital or analogue. This can also be expanded using the low-power Radio Frequency (RF) network option available.

It is generally possible to use modern, USB-based memory sticks under Linux; however, not all USB memory sticks will work on our systems. Most USB memory stick devices produced since 2003 will work, while older devices are less likely to be supported. In general, the older the device, the less chance that it will work. The only way to know for sure is to try to use it. We do not provide any kind of card reader on any of the machines.

Yes but they will only work at USB 1.x speeds. The only time you will get the full 480Mbps speed out of a USB 2.0 controller is if you are using a true USB 2.0 device. Back To Questions

NT4 does not have usb support, and we recommend our users to use either Win 98 or Win 2000. We can offer support for NT4 only for large customers under special conditions for our devices- including usb to serial or parallel.

You can go 5 meters or around 16 feet from a computers USB port or from a powered USB hub to a USB device. Back To Questions

The best answer to this is a firm "maybe". DOS device drivers are available for most USB and Firewire controllers. If such drivers are added to a DOS boot diskette so that your USB or Firewire drive is "seen" by DOS, SpinRite will also be able to "see" and operate with it. However, the performance of the drive through the DOS drivers and the serial (USB/Firewire) cable will likely be far lower than if the external drive were connected directly to a PC's motherboard controller.

Even with the latest Service Packs installed offering support for some USB devices the USB controllers require Windows 98.

At this time, only Windows/DOS FAT (vfat, fat32) are supported. If there is sufficient interest, we could investigate adding Linux ext2/ext3 support. (Contact us if you want this support to be added.) We do not support NTFS (NT, XP), HFS+ (Mac OS), or other formats; do not your USB device using those filesystem formats if you plan to use it on the Linux lab machines.

Yes. Desktop Authority allows you to centrally allow and/or deny devices based on device serial number, or VID/PID combination.

The nice thing about 4PSA Server Controller is that it scales with the number of servers. It really does not matter if you have a server, three servers or fifty servers. All the servers will be available on the navigation menu and you can switch between them with a mouse click. Yes. 4PSA Server Controller will render usage graphs for all monitored servers. It will draw on the graph area any parameter chosen by the administrator.

We recommend no more than 30 total per week (i.e., the standard intensive 20, plus an extra 10), as there is homework and preparation for each class. Yes! Our Japanese through Pop Culture and Japanese and Traditional Culture courses both have a conversation class component. Of the 20 lessons a week, 10 are in your chosen subject area, and 10 are conversational Japanese courses. Yes, even without taking the Japanese and Traditional Culture course, you can attend specific cultural activities.
