The Model 4176 media converter from Electro Standards Laboratories is a ruggedized device that converts USB 2.0-compliant data from a standard PC to a serial asynchronous data interface over RS232 or RS485/422 networks. The user-selectable baud rate provides operating speeds up to 1.5 Mbits/sec for RS232 and up to 3 Mbits/sec for RS485/422. Electro Standards Labs says the typical applications for the Model 4176 include USB PC-to-PC long-distance communications, factory automation, multi-drop data collection devices, barcode readers, time clocks, scales, data-entry terminals, ATMs and serial communications in harsh environments.
This converter features electrostatic discharge protection circuitry on the USB I/O connector as well as all receivers and transmitters for both the RS232 and RS485/422 interfaces. It is designed to operate from -40 deg. Celsius to +85 deg. Celsius.
The desktop converter can be ordered with the USB I/O connector on the front or back of the unit. Accessories include DIN rail mounting hardware. The unit is also available as a board only (Model 4177), with front mounting threaded brackets for rack mounting in embedded applications.
