Specifications

Details

The Model 4177 is a high speed ruggedized USB to RS485/422/232 interface converter board from Electro Standards Laboratories. With its integrated rate buffering, the Model 4177 converts USB 2.0 compliant data from a standard PC to a serial asynchronous data interface over RS232 or RS485/422 networks. The baud rate is user selectable with operating speeds up to 1.5 Mbps for RS232 and up to 3 Mbps for RS485/422.

When operating in RS485 (RS422 compatible) mode, the converter can be configured for 2-wire half duplex or 4-wire full duplex operation. This converter provides an industrial solution for applications requiring a single point-to-point or a multi-point communications link over short and long distances. Typical applications 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.

The Model 4177 is designed to operate from -40°C to +85°C and is a member of the Electro Standards Laboratories rugged media converter family. The unit features ESD protection circuitry on the USB I/O connector as well as all receivers and transmitters for both the RS232 and RS485/422 interfaces. The unit's power input is protected from transients. Other features include user selectable asynchronous data format, TX, RX and Power indicator LEDs.

The Model 4177 converter is available as a board only with front mounting threaded brackets for rack mounting in embedded applications.

DESKTOP UNIT
It is also available in a desktop package (Model 4176) for applications that require an enclosure. In this configuration it can be ordered with the USB I/O connector on the front (default location) or back of the unit. Accessories include DIN rail mounting hardware.
