I-9144i
4-port Isolated RS-422/485 Module
Features
• 4 Isolated RS-422/485 Ports
• Baud Rate of up to 115200 bps
• Internal 128-byte Hardware FIFO for Each Port
• Built-in Self-Tuner or Auto-Direction Control
Introduction
The I-9144i provides 4 isolated RS-422/485 serial ports. Each port is equipped with a 128-byte hardware FIFO 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-9144i 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.
