Connect Tech Echo/ISA - Legacy ISA Based 8 Port Serial Interface Card

Adds Eight RS-232/422/485 Ports to a PC via Legacy ISA Bus

Introduction

The Echo/ISA is an 8 port serial card designed for those needing continued support for ISA bus based systems. Multiple Echo boards can reside in a system to accommodate large multi-channel I/O requirements. This flexible solution enables independent configuration of each port's baud rate, parity, data and stop bits, and supports the most popular operating systems.

Features and Benefits

  • Flexibility: Available in 8 asynchronous ports of RS-232 and/or RS-422/485.
  • Performance: 16554 UARTS control each port with up to 64 bytes of transmit and receive FIFO buffers.
  • Speed: Supports data communications speeds up to 115.2 Kbps.
  • User Definability: IRQ lines are jumper selectable, each port can be independently configured for baud rate, parity, data and stop bits.
