The Industrial Automation Group of Advantech introduces the USB-4604B and USB-4604BM, USB to 4-port RS-232 and USB to 4-port RS-232/422/485 converters. Both models offer plug-and-play serial connectivity for USB equipped PCs and systems and since they are USB-powered there is no need for additional power supplies.

The USB-4604B and USB-4604BM are both fully USB v1.1 and v2.0 compliant and feature serial communication rates of up to 921.6 kbps. The USB-4604BM provides software selectable RS-232/422/485 settings for each port and automatic RS-485 send data control. Both models include 16KV electrostatic discharge (ESD) and utilize standard DB9 male connectors, so that common PC cables can be used without additional adapters.

To ensure a reliable USB connection, an innovative type-B USB connector with thumbscrews makes sure that cable stays connected despite vibration or inadvertent tugging on the cable. For convenience, a USB cable with locking connector is included with each unit.

Packaged in rugged ABS plastic, the USB-4604B and USB-4604BM are ready for DIN-rail or direct panel/wall mounting, using included brackets. Drivers are included for Windows™ 2000/2003/XP and CE 5.0.
