Asynchronous and Synchronous Communication

The Hostess range of multiport serial controllers includes both intelligent and non-intelligent synchronous and asynchronous products designed to meet your needs. Widely used by many major OEMs and System Integrators, they are simple to install and easy to use.

 

Hostess and Hostess 550

These were the first multiport controllers for the PC and are still in use today in a wide range of systems. They provide a low cost asynchronous solution using non-intelligent controllers.

 

Features include

Full Modem control Wide range of I/O addresses and interrupts Extensive Programmers guide Unique poll register Interface options include RS232/422, Current Loop and RS485 FIFO buffering on the Hostess 550 to reduce number of interrupts

 

Hostess i

The Hostess i range of intelligent controllers enables you to download code to the controller to reduce the load on the computer's CPU. Available soon in PCI format.

 

Features include

V.53 12 MHz processor for down loadable programs 128k dual ported RAM expandable to 8 Mb All models include two full duplex synchronous ports 8 and 16 port models Wide range of device drivers 1.1 Mbps synchronous, 38.4 Kbps asynchronous RS232/422 interface options Developer’s Toolkit available

 

Hostess i/S2

This synchronous two port intelligent controller has the same powerful features as the Hostess i series and is ideal for off loading system overhead by running synchronous protocols on the controller.

 

Features include

Two DB15 high density connectors on the controller Full modem control Synchronous data rates up to 2 Mbps Developer’s Toolkit available

 

Hostess SV24+

For low cost synchronous communications the Hostess SV24+ is an economical 2 port non-intelligent controller that can operate at speeds of up to 1.28 Mpbs and supports both full and half duplex data transfer modes.

 

Features include

Single synchronous V.11, X21 network connection or two V.24 synchronous connections SynchLink software provides drivers for Windows NT and Windows 95 and an API for low level control of the SV24+ communications

 

Smart Hostess

The Smart Hostess can provide 4 or 8 ports that can operate either synchronously or asynchronously giving considerable flexibility. Programs can be downloaded to the board to reduce CPU load.

 

Features include

Synchronous speeds of up to 1.1 Mbps using DMA. Asynchronous speeds up to 76.8 Kbps 8 MHz processor with 256K dual ported RAM and 256K local RAM to accommodate the down loadable programs. Field upgrade from 4 to 8 ports

All Hostess controllers come with full technical support and an excellent 5 year warranty. Specifications are subject to change at any time and without notification.
