Smart multiport serial boards

October 2004 Motion Control & Drives

Moxa Technologies, a leading industrial device networking solution provider, has recently developed a Moxa turbo serial engine. Moxa says that this specially designed semiconductor chip is being used to make its second generation of smart multiport serial boards the top performing boards in their class.

The stamp-sized MU860 turbo serial engine, which incorporates Moxa's 17-plus years of experience in serial board design, combines a high-performance UART with burst data mode, on-chip hardware/software flow control and PCI bridge, and on-chip ADDC for RS485 communication. These special features push serial communication throughput to over 700 Kbps per port - its manufacturers claiming that the MU860 is the most powerful UART chip in the world.

Features include:

* 8-port UART with 128-byte FIFO and burst data mode.

* On-chip hardware, software flow control and ADDC (automatic data direction control).

* 3,3 V/5 V PCI version 2.2 controller.

* On-chip RS422, 2-wire RS485, 4-wire RS485 control circuit.
