ExpressCards Explained
The 411 on ExpressCards
Have you recently purchased a laptop only to discover your PC Card won't fit? Instead of toying around to find a new technology solution, look to Quatech to fulfill your mobile communication needs.
If you purchased a laptop, but your current PCMCIA card does not make a correct connection, it could be your new device is only compatible with ExpressCards. Because of changes in laptop technology, traditional mobile connectivity solutions - such as parallel and serial PCMCIA cards - have been replaced by smaller, thinner modular ExpressCards.
ExpressCard Connectivity and Performance Series products are:
- 34 form factor that is 100% compatible with new laptop models
- Easy, seamless transition from PCMCIA to ExpressCard
- PCIe and USB 2.0-based designs
- Performance Series for native serial and true parallel connections
- PCIe-based design can still directly use I/O space addresses and interrupts, thus emulating built-in ports

Quatech launched the ExpressCard Connectivity and Performance Series' products to carry forward the benefits of plug-in I/O cards for the next generation of mobile computing devices.
There are two standard formats of ExpressCard modules - the ExpressCard/34 module and the ExpressCard/54 module. Quatech offers the ExpressCard/34 module, yet also fits in to a 54 module slot, as both sizes use the same connector interface.
As the leader in PCMCIA technology with reliable Serial and Parallel PCMCIA Cards, Quatech broadens its mobile connectivity line with the ExpressCard Performance Series and Connectivity product lines. The emerging technology has a smaller design, faster speeds, better efficiency with more robustness, the Performance Series connects high bandwidth peripherals to notebooks.
Utilizing a PCIe-based design, the ExpressCard Performance Series can still directly use I/O space addresses and interrupts, thus more closely emulating built-in ports than can be done via USB-based design. Because there is no USB stack for the drivers to contend with, throughput can be higher and latency will be lower.
Quatech's PXP series is a great solution to connect with existing peripherals and maintain compatibility and functionality with their current application software. For more information, please visit Quatech's ExpressCard pages. |
