Module 2 cổng RS-422/485 ICP DAS I-8142iW-G CR
Feature
• Serial Port with +/-4 kV ESD Protection
• Baud Rate of up to 115200 bps
• RS-485 Auto-Direction Control
• 2500 VDC Isolation
• Internal 128-byte Hardware FIFO for each Port
• LED Indicators for TxD, RxD and Power Status
Introduction
The I-8142iW-G provides 2 isolated RS-422/485 serial ports, while the I-8144iW-G provides 4 isolated RS-422/485 serial ports. It is equipped with a 128-byte hardware FIFO for each port and offers speeds up to 115.2 kbps with support for RS-422 full-duplex communication. In the harsh industrial environment, the onboard ESD protection devices can divert this potentially damaging charge away from sensitive circuitry and protect the I-8142iW/I-8144iW from permanent damage. The serial communication modules are designed for use with intelligent devices like bar code readers, serial printers, intelligent sensors, instrumentation equipment, computers, and almost any device with an RS-422/485 port.
