.jpg) | Model 4149 Very High Speed Ruggedized Fiber-to-RS232/422/485 Interface Converter, Desktop Configuration. The Model 4149 is a very high speed ruggedized Fiber to RS485/422/232 interface converter. Typical operating speeds are as follows: Up to 1.5 Mbps for RS232 to fiber conversion, Up to 5 Mbps for RS485/422 to fiber conversion. The Model 4149 is designed to operate from -40°C to +85°C, it is a member of Electro Standards Laboratories' (ESL) rugged community fiber-to-copper media converter family. The Model 4149 features protection circuitry on all receivers and transmitters for both RS232 and RS485/422 interfaces. The unit's power input is protected from transients and features 3kVDC isolation to prevent system ground loops. It can be powered from a wide input range of 10VDC-36VDC, with modules also available for other voltage ranges such as 4.5VDC-9VDC and 19VDC-72VDC. Other features include user-selectable fiber polarity, dual DB9 power connectors (board only) for convenience in bused power applications, TX, RX and Power indicator LEDs. This converter is available as a board only, Model 4159, Cat. No. 304159, with front mounting threaded brackets for rack mounting in embedded applications. For applications that require an enclosure, it is available in a desk top package, Model 4149, Cat. No. 304149, with optional DIN rail mounting hardware.

.jpg) | Model 4176 High Speed Ruggedized USB to RS485/422/232 Interface Converter, Desktop Configuration The Model 4176 is a high speed ruggedized USB to RS485/422/232 interface converter from Electro Standards Laboratories. With its integrated rate buffering, the Model 4176 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 4176 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 4176 is a desktop package for applications that require an enclosure. In this configuration it can be ordered with the USB I/O connector on the front (default location) on back of the unit. Accessories include DIN rail mounting hardware. This converter is also available as a board only, Model 4177, with front mounting threaded brackets for rack mounting in embedded applications.
