Introduction
RS-422/485 PC/104 embedded module combines small size, industrial grade construction and reliability specifications plus performs the functions most commonly need in embedded application.
Because PC/104 modules uses smart stacking bus design, they avoid the costs and bulk associated with backplanes or card cage. It work with PC/104 CPU boards that accept the PC/104 expansion interface, and comes with DB9 or DB25 connection cables are available as options to meet users' varied connection requirements.
Feature
- Low RMA rate and high reliability with single chipset designed ASIC
- Industrial grade design for stability and reliability
- RS-422/485 Auto Identify and Switch technology enable device plug-n-play without jumper or switch setting
- ARSC™ (Auto RTS Signal Control) technology allows accurate switching of the transmitter on and off for precise timing of the data transmission
- RS-422/485 Handshaking Communication provides hardware flow control for best prevention of data error or data lost
- Built-in termination resistors to avoid cross-talking
- RS-422/485 industrial host controller series are certified by CE, FCC approval
- Support Microsoft Windows, Linux, and DOS
