The EASY COM intelligent serial package is the Corollary 8*4 adaptor and 8/tc concentrator compatible product, which contains one intelligent serial adaptor and one terminal concentrator. Each terminal concentrator provides eight asynchronous serial communication ports (RS232), which transmits communication signals by using the cable with an 8-pin mini-DIN connector to intelligent serial adaptor. The hardware configuration of intelligent serial adaptor and 8 port terminal concentrators are shown in below. User may use this configuration to link the computer and serial peripheral devices such as serial printers, plotters etc.

Each EASY COM intelligent serial adaptor can be used to connect up to four terminal concentrators, total 32 RS232 ports are provided. Up to four EASY COM intelligent serial adaptors can be inserted into one computer system, so that it supports 128 ports in one computer system.

The advantages of using EASY COM intelligent serial adaptor and 8 port terminal concentrators are that when you construct the communication link from PC to peripheral devices, you only need to use one inexpensive cable line to replace the eight RS232 cables, it extends communication distance and reduces cabling cost. Each intelligent serial adaptor contains four high speed communications links, so that it can connect to four terminal concentrators, which only needs to use four inexpensive cables rather than RS232 cables.

The EASY COM intelligent adaptor is particularly suited to facilitate the connection of terminals (VDUs) in multi-user operating systems. Each package is supplied complete with one terminal concentrator containing eight female DB25 connectors. If extra concentrators are needed, please order the concentrator item.

The EASY COM intelligent serial board can be installed in any IBM PC/AT, PC/386, PC/486 or hardware compatible system. To accommodate a variety of operating systems, the distribution diskettes contain many device drivers for the operating system you need.

The architecture of EASY COM intelligent package provides the distribution multiprocessor I/O system, both intelligent serial adaptor and terminal concentrator use HIGH intelligent CPU main processor which handles send and receive functions between the intelligent serial adaptor and terminal concentrators, it saves the workload of the host computer.
