Intellicon Flex-8

  • Port Density: Provides eight asynchronous serial ports.
  • Adaptability: SLIM technology allows choice of RS-232, RS-422/485, RS-423 and/or 20 mA Current Loop interfaces. Offers full support for half duplex and full duplex RS-485 communications.
  • Performance: Features a Zilog Z80B on-board processor and 64K dual-ported RAM.
  • User Definability: IRQ lines are jumper selectable. User can also software select options such as Edit, Echo, I/O Flow Control and Character Translation to be processed on the Intellicon.

More Information

The efficient Intellicon-Flex 8 provides eight ports of reliable data transfer, and the flexibility to customize your adapter to meet your specific I/O requirements. The use of our Serial Line Interface Modules technology means you can house different electrical interfaces on the same board, and allows for cost-effective field upgrades should the need arise in the future. An intelligent communications processor offloads the burden of managing communications from the main CPU, resulting in efficient I/O communications and better processing performance for the host system.
