The USB EasyTap module is a generic USB < > serial converter and provides a painless way to
get your project interfaced to the otherwise complex USB port on your PC. No need to worry about
writing your own device drivers since they are included. It can be used in several different ways
depending on your needs. By adding a standard TTL < > RS-232 level converter it works like a high
speed USB < > RS-232 adapter (with or without hardware handshaking) and you can use it to
interface any legacy RS-232 product.
If your need is to interface a MCU (BASIC Stamp, AVR, PIC, SX, 8051, 68HC11 etc.) to the USB
port you can do this directly without using any TTL < > RS-232 level converter and therefore skip
the added costs (and space) for a level converter.
The third option you have is to use the integrated EasyTap network to build a multi master (or
master-slave) control network connecting other network nodes via twisted pair cable up to
1200 meters (4000 ft) in a very cost effective way.
Whatever interfacing method you choose you communicate with your hardware just like it was
connected via a standard high speed serial port thanks to the included Virtual COM Port driver.
This means that all your old tools (OCX's, Delphi components, LIB's etc.) and software works
just like before but your hardware is interfaced via the USB port. Some typical applications are...
| - USB <> Legacy RS-232 interface | |
| - Generic USB <> MCU interface | |
| - Generic USB <> serial interface | |
| - USB <> RS-422/RS-485 interface | |
| - USB <> USB data transfer cables | |
| - Home Automation infrastructure | |
| - Control network infrastructure | |
| - USB <> PDA interface cables |
