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.

No. Quatech USB to serial adapters do not also included hubs. However, you can purchase third-party USB hubs to add additional USB ports to your system. The maximum data rate for USB 1.1 is 12 Mbps. USB 2.0 devices are capable of speeds up to 480 Mbps. Quatech USB 1.1 compatible serial adapters can reach speeds of 460.8 kbps--more than fast enough for most serial peripherals. Thus, there would be no advantage to implementing USB to serial adapters on the USB 2.0 standard. No.

Connecting the digitizer with Serial (RS232) or USB will be determined by the application software you are using with the digitizer. Please consult your application support for assistance.

Refer to the Quatech COM CD from which you installed your unit, or the installation files you downloaded to your hard-drive and used to install your USB serial port. Look for the history.txt file. Open this file and you will see the revision history for that driver. The most recent information will be at the top of the file.

The DSU/QSU/ESU/HSU-200/300 adapters operate in Full Duplex mode by default. The boards may be optionally configured by the user for Half-Duplex with RTS, Half-Duplex with DTR or Half-Duplex with Auto Transmitter Control modes of operation

In version 1, your serial number is printed on a white label on the front of the sleeve of the CD-ROM. It may also be printed on a label on the outside of the white shipping box. The format of the serial number is XXXX-YYYY-YYY-YYY where XXXX are letters. In release 1.0.1, it does not matter whether you type a zero or the letter 'o' for '0' nor whether you type a one or the letter 'i' for "1". In release 1.0, be sure to type one, not 'i', and zero, not 'o'.

Yes. A separate, Keyspan brand USB adapter can be purchased for your board. The adapter attaches to the end of the serial cable provided and then connects to your computer. The USB adapter can be purchased through GTCO or your local reseller.

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

Your software will support more than the standard four (COM1-COM4) COM ports available to the machine You have enough available slots in the machine (up to eight slots). The following outlines Quatech support provided for different operating systems. Windows 95/98/Me/2000/XP is able to support many more than four ports at one time. Quatech's driver must be used in order to access ports above COM 4. OS/2 also should have no problem accessing the cards up to COM32.

Quatech provides Windows CE drivers for our asynchronous serial PCMCIA cards. As Windows CE is implemented differently in different systems, the Quatech standard driver contains support files for only the most popular CE-based handheld devices. Click here for a list of supported devices. If the standard driver does not work with your equipment, please submit our Technical Support Request form to get the appropriate files for your system.

Solaris supports Digi InsideOut Networks' devices and recently, KeySpan and Prolific chipset based devices' support were also integrated to Solaris. Keyspan and Prolific USB serial drivers are available in Solaris Express dated 2/2006 and in Solaris 10 Update 2 and later. PL2303 chip based adapters and Keyspan USA-19HS adapter are available as part of Solaris 10 Update 2. Keyspan USA-49WLC adapter is supported in Solaris Express dated 3/2006 and will be available in Solaris 10 update 3.

Sorry, no. Today's PDAs do not host devices. They can only be slaves. Since our product requires a host, a USB adaptor won't work either. Currently we have no version that doesn't require a host.

Either type of connection will work if you have the correct port available on your PC. If you have Ethernet ports available these are often the best choice as they do not require software installation to function. USB is the other popular option and provides good connectivity after you install the adapter's driver software. Examples: Linksys Wireless USB adapter for Desktop or Netgear Wireless USB adapter

AutoEnginuity has verified our product with dozens of USB-to-Serial adaptors (IO Gear, Prolific, Belkin, etc.). This adaptor can also be purchased from us. Note: Not all USB-to-Serial adaptors are made equal. We have tried some based on the FDTI chipset (Cables Unlimited), KeySpan, the "<10$ eBay unit", and Radio Shack are NOT compatible. We highly recommend getting any of the above or anything based on the Prolific-chipset from a reputable company.

No. According to the license agreement for RapidSketch each machine must have its own serial number. The first machine's license costs $100 and additional machines can be purchased for $50 each.
