Quatech RS-422/485 serial CompactFlash cards are an ideal solution for adding additional ports to full and half duplex multi-drop systems. Handheld devices are becoming increasingly popular choices for a wide variety of portable testing, monitoring, and control applications that require RS-422/485 connectivity. Quatech's SSCF-200/300 is small, light-weight, and has low power requirements, including a special feature that automatically reduces power consumption when terminal equipment is not connected. In addition, ESD protection is provided, and the cards are housed in a sturdy metal case with a convenient removable connector cable.

Quatech CF cards provide industry-leading speeds of up to 921.6 kbps by employing a clock multiplying feature in conjunction with 16550 UARTs. The cards are supported under Windows CE and Pocket PC, making them ideal choices for the most popular handheld devices, which never come equipped with RS-422/485 ports. Support is also provided for Windows 95/98/Me/2000/XP and DOS, enabling the cards to be used with most Tablet, Laptop, and Desktop PCs as well.
