This DFlex adapter is a standard multi-port serial adapters that allow multiple serial devices with different electrical interfaces, such as RS-232, RS-422/485, RS-423 and 20mA current loop, serial ports for connecting data collection devices, barcode readers, time clocks, scales and many other serial devices. DFlex adapters with their electrical interfaces on Serial Line Interface Modules (SLIMs) provide highly flexible, industrial strength solutions for control and automation applications using ISA bus compatible computers.. They provide highly flexible solutions for software applications requiring multi-channel serial I/O and offer data transmission rates up to 460K baud.

FEATURES:
• Different models of DFlex adapters may reside in a host computer offering up to 32 ports per system.
• 16550 16650 or 16750 UARTs control each port.
• An addressable status control register to improve performance.
• Each port on a DFlex-2/-4/-8 has independent baud rate selection offering baud rates from 50 - 115K baud with 5 6 7 or 8 data bits and 1 1.5 2 stop bits odd or even parity.
• Each port on a DFlex-2/-4/Fast has independent baud rate selection offering baud rates from 200 - 460K baud with 5 6 7 or 8 data bits and 1 1.5 2 stop bits odd or even parity.
• On board DIP switch allows the selection of ports 1 & 2 as COM1 and COM2. It provides 8 predefined I/O address sets and 8 predefined status port addresses.
• Jumpers on the board give the user a choice of 8 IRQ lines to run the board at. The on board DIP switch also provides the choice of running the DFlex on 1 or 2 or no hardware interrupts.
• System requirements are one full (DFlex-8) or half-length (DFlex-2/-4; DFlex-2/-4/Fast) ISA bus compatible slot; one available IRQ line.
