The Sigma-22 is a middle speed (up to 384 kbps) synchronous/asynchronous adapter intended for use with IBM PC and compatible computers.

Sigma-22 adapter is based on the CL-CD2431 controller chip (a product of Cirrus Logic Corp., USA). It supports master mode DMA data transfer providing the most efficient use of the PC input/output bus. Interface options cover RS-232, V.35, RS-530 and RS-449 standards. The adapter is software-configurable. Only I/O Base Address is jumper selectable.

The Cronyx-Sigma software allows to join several physical synchronous communication channels into one logical channel. For example, two channels with data rate 128 kbps, joined together, will create the logical channel with the overall throughput of 256 kbps.

There are several models of Sigma adapter available, supporting different serial interfaces.

Currently available models are listed in Prices. Please, contact technical support if you are unsure which model to choose.
