.jpg) | Model 4149 Very High Speed Ruggedized Fiber-to-RS485/422/232 Interface Converter. The Model 4149 has typical operating speeds of 1.5 Mbps for RS232 to fiber conversion and 20 Mbps for RS485/422 to copper conversion. Designed to operate from -40 degrees C to +85 degrees C, it is very rugged. Model 4149 features protection circuity 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 9VDC-36VDC, with models also available for toher voltage ranges such as 4.5VDC-9VDC and 18VDC-72VDC. Features include user selectable fiber polarity, dual DB9 power connectors (board only) for convenience in bused power applications, TX, RX, and Power indicator LEDs. | ||

.jpg) | Fiber 485, Models 4127 / 4129 HP Fiber / RS-485 Converters - Allow Connection of HP Fiber Optic Linked Terminals to RS-485 Port of Controller Models 4127 / 4129 Application The Fiber 485, HP Fiber / RS-485 Converters are used to connect fiber optic linked terminals to a controller having an RS-485 / RS-422 interface port. While RS-485 is a versatile communication standard, able to communicate over long distances and at fast data rates, conversion to a fiber optic communication standard also allows data transmission that is no longer susceptible to electrostatic or electromagnetic fields. Additionally, the ports of the connected terminals are protected from damage by potential differences (ground variations) that often exist between them. Fiber 485 Features - Model 4127: RS-485 / RS-422 connection via a DB-15 connector. - Model 4129: RS-485 / RS-422 connection via an RJ-45 connector. - Converts RS-485 / RS-422 Serial Communication Interface to HP Versatile Link plastic core cable. - Provides full galvanic isolation (no metallic connection) between connected devices. - Full duplex connection between two devices having RS-422 ports. - Allows the interference-free fiber optical transfer of data to be utilized by the device having an RS-485 / RS422 interface. - Data transfer rate greater than 20 Kbps. - Fiber connections via two standard Versatile Link connectors. - Configurable for use at DCE or DTE (specify with order). - Link distance: greater than 500 meters (1640 feet) with 200 mm Hard Clad Silicon fiber cable. - Provided with external wall-mount power supply, UL approved. Fiber 485 Specifications: - Data Transfer Rate: Greater than 20 Kbps - Fiber Transmission Distance: 75 m (250 ft.) using TC 1000 W type plastic fiber cable. - RS-485/422 Transmission Data: Greater than 300 m (1000 ft.) - Optical Fiber Connectors: HP/Agilent Versatile Link - RS-485 Connector: DB-15 female on Model 4127, RJ-45 female on Model 4129 - Optical Cable Type: 1mm plastic optical film - Optical Wavelength: 660 nm (red) - External Power Supply: 120 VAC, 60 Hz - Dimensions: 5.5" x 2.25" x 1.0" (139mm x 57mm x 25mm). - Weight 0.5lb (226 grams) - Status Display: Red LED | ||
