Description
Quatech's RS-422/485 serial boards are available with either two or four
ports. The ports are jumper configurable for either RS-422 or RS-485 in
any combination for full and half duplex networks. PCI registers are properly
implemented to assure that Plug-and-Play works reliably, and that the
board will not cause PCI bus conflicts. The QSC-200/300 board implements 16750 UARTs containing 64-byte FIFOs, while the DSC-200/300 executes 16550 UARTs with 16-byte FIFOs. They use a clock multiplying feature
allowing them to achieve data rates up to 921.6 kbps.
To maintain maximum signal integrity, Quatech uses a four-layer board
design. But, for even more protection in industrial environments, an optional
surge suppression package is available. This "IND" option applies
a surge suppressor to each line that is capable of sustaining up to 40A
peak, 8 x 20µs transient surges, a clamping voltage of 15.5V and
a peak energy dissipation of 0.1 Joules. (Note that implementing the IND
option restricts the board's speed to 115.2 kbps.)
