Module 4 cổng RS-422/485 ICP DAS I-8144-G CR
The I-8144 provides 4 non-isolated RS-422/485 serial ports. It is equipped with a 128-byte hardware FIFO for each port and oﬀ ers 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-8142/I-8144 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.
