High-speed Adapter Tau

Discontinued, recommended replacement is: Tau-PCI

Specifications
Documentation

High-speed Adapter Tau Features:
  • Two full duplex ports
  • Up to 4 Mbps per channel per direction
  • V.35/RS-232 or RS-530(RS-449)
  • Independent synchronous/asynchronous mode selection per port
  • Full modem control
  • DMA bus master

Cronyx-Tau is a high speed (up to 4 Mbps) ISA Bus Master synchronous/asynchronous multiplexer that allows to connect IBM PC and compatible computers to the modern communication equipment such as HDSL or Fiber Optic modems. Its options include sophisticated interfaces for direct connection to G.703 (2048 kbps) communication channels or E1 Fractional services (see Chapters "Short Range Modems" and "Digital Service Access Devices".)

The key element of Cronyx-Tau is HD64570 controller chip (a product of Hitachi Corp., Japan). Interface options cover RS-232, V.35, RS-530 (RS-449), G.703 (2048 kbps) and E1 standards. The adapter is software-configurable. Only I/O Base Address is jumper selectable.

The Cronyx-Tau software allows to join several physical synchronous communication channels into one logical channel. For example, two channels with data rate 2 Mbps, joined together, will create the logical channel with the overall throughput of 4 Mbps.

There are 7 models of Tau adapter available, supporting different serial interfaces:

Ordering Code Channel 0 Interface Channel 1 Interface
TAU RS-232/V.35 * RS-232/V.35 *
TAU/VR RS-232/V.35 * RS-530 (RS-449)
TAU/R RS-530 (RS-449) RS-530 (RS-449)
TAU/E1 E1 E1/RS-232/V35 **
TAU/E1/R E1 E1/RS-530 (RS-449)
