Описание 

Quatech's ESC-100D leverages the PCI 2.1 specification to provide multiple serial ports while using minimal system resources. The ESC-100D requires only one PCI slot to provide eight independent RS-232 ports. All eight channels are addressed in a continuous 64-byte I/O block for simplified software access. All channels share a single PCI interrupt, and an interrupt status register is available for determining the interrupt source. As the ESC-100D completely conforms to the PCI specification, Plug & Play capability is assured.

The ESC-100D is implemented with eight 16750 UARTs containing 64-byte FIFOs. It has a clock multiplying feature allowing the board to achieve data rates as high as 921.6 kbps. The high clock speeds and deep FIFOs will greatly reduce CPU overhead, making the ESC-100D an ideal choice for heavy multi-tasking environments.

For optimal performance in industrial settings, Quatech's ESC-100D uses a four-layer board design. For even more protection, an optional surge suppression package is available. This "IND" option (ESC-100IND) applies a surge suppressor to each line that is capable of sustaining up to 40A 20ms peak transient surges, a clamping voltage of 30V, and a peak energy dissipation of 0.1 Joules. (Note that implementing the IND option restricts the board's speed to 115.2 kbps.)

The ESC-100D connects to serial devices using the included cable which provides eight standard DB25 male connectors. The board is also available with a DB9 male connectors as model ESC-100D-D9.
