Performance PCIe based RS-422/RS-485 Serial ExpressCards

Synchrotech is now offering Quatech's 1, 2, and 4 port PCIe based ExpressCard to RS-422 and RS-485 Serial host adapters. Advantages of a PCIe-based ExpressCard design are in the interface to the laptop's motherboard. The PCIe bus interface is the successor to the PCI bus, which in turn was the successor to the ISA bus to which built-in serial ports were originally attached. As such, the ExpressCard adapter design utilizes a PCIe-based design and 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. Moreover, because there's no USB stack for the drivers to contend with, throughput can be higher and latency will be lower (considerably so in many cases). Due to improved data transfer rate, the ExpressCard is considerably more efficient for multi-tasking operations.

New FAQ: Considerations for Ratoc's FireWire and USB 2.0 to SCSI Adapters

Recently there has been a shift in interest from internal SCSI host adapters SCSI host adapters utilizing external busses like high performance FireWire and prosaic USB. While Ratoc's FireWire and USB to SCSI adapters have been on the market for quite some time, they are beginning to grow in popularity since they are an inexpensive and accessible way to work with older SCSI devices. This FAQ document is intended to clear up some of the confusion over deploying Ratoc adapters with SCSI devices.

Covered in the FAQ: matching SCSI connector types, Term Power and other power considerations, SCSI converter adapters, and links to compatibility lists.
