FHL-8124 V.24 RS-232

OVERVIEW

The Fraser's Hill FHL-8124 is a low cost, high performance, single channel, synchronous and asynchronous, multiprotocol V.24 RS-232 serial communications coprocessor card for the IBM PS/2 and compatible personal computers using the Micro Channel architecture.

• Standard full size Micro Channel adapter.
• Intel or AMD 80C186 10, 12, 16, or 20 MHz microprocessor.
• Zilog Z85230 8, 10, 16, 20 MHz serial communications controller.
• 64 kilobytes to 1 megabyte static RAM, fully addressable from the PC through two 16 kilobyte windows.
• One CCITT V.24 / EIA RS-232 port, synchronous or asynchronous, with data rates up to 256000 bps.
• Synchronous mode supports: SDLC, HDLC, Bisync, or Monosync protocols; NRZ, NRZI, FM0, or FM1 data encoding.
• Asynchronous mode supports: 5, 6, 7, or 8 data bits; 1, 1.5, or 2 stop bits; odd, even, or no parity.
• Bidirectional software controlled interrupts between host PC and 80186 microprocessor.
• Two on-board DMA channels to increase performance.
• User configurable memory window addresses, I/O addresses, and IRQ level.
• Built-in null modem with synchronous clocking.
• Communications protocols, such as SNA or X.25, can be implemented entirely on the board, with a high level software interface to PC application and terminal emulation programs.

ORDERING INFORMATION
