In-line USB Converters USOPTL4 & USPTL4 PRODUCT FEATURES * * * * * * * Models USOPTL4 and USPTL4 are USB to one port RS-422/485 converters. Supporting 2-wire RS-485 or 4-wire RS-422/485 communications, these devices are great for applications requiring long range or multi-drop capabilities. Both models use pluggable terminal blocks on the RS-422/485 side. Two LEDs indicate data transmit or receive. Model USOPTL4 includes circuitry with 2000 Volts isolation protection against ground loops and voltage spikes. Both products draw power from the USB port so no power supply is required. Simply install the drivers supplied on CD ROM and plug the converter into an available USB port on your computer or USB hub. The device show ups as an additional COM port in the Windows Device Manager, and is compatible with Windows applications. Universal Serial Bus (USB) has become the connectivity workhorse of today's PCs, replacing classic serial ports. But many commercial and industrial devices still use RS-422/485 interfaces. To connect these devices to modern PCs you need robust and reliable conversion solutions. USB ports are becoming more common on commercial and industrial equipment such as point-of-sale peripherals, medical devices, scientific instrumentation, laboratory equipment and other devices or in environments where surges, spikes and ground loops are likely to occur. RS-485 Control No special software is required to control the RS-485 receiver or transmit line driver. The driver is automatically enabled during each byte transmitted in RS-485 mode. The transmitter is always enabled in RS-422 mode. The receiver is tri-stated during each byte transmitted in the echo-off mode. The receiver is always enabled in the echo-on mode. There are 4.7k Ohm pull-up/pull-down resistors on the RDA and RDB lines. A termination resistor may be added to R16 if needed. See B&B's RS-422/ RS-485 Application Note (available on our website) for more information on termination and DC biasing of an RS-485 network. 2000 V RMS optical isolation 15KV ESD surge protection Adds a COM port to your PC LEDs for transmit and receive lines USB 1.0, 1.1 and 2.0 compatible (12 Mbps) Automatic configuration on Windows 98, ME, 2000, XP, Vista. 7 (32/64 bit), 8 (32/64 bit) No power supply required (powered from USB bus) Ordering Information Model Number Description USOPTL4 Isolated RS-422/485 Inline USB Converter USOPTL4-LS Locked Serial Number Version of USOPTL4 USPTL4 Non-isolated RS-422/485 Inline USB Converter USPTL4-LS Locked Serial Number Version of USPTL4 Accessories 9PAMF6 - DB9 to DB9 serial cable, male to female, 6 ft. (1.8 m) TB5P508SR-2PK - 5-position terminal block with strain relief paddle board, 2 pack Locked Serial Numbers Explained We configure our single-port USB to serial converters in two ways. In standard format, each product has a unique serial number. "Locked serial" format uses the same serial number that is associated with a model type. If your converter will always be used with the same computer, the standard serialized model is all you need. If the converter is shared among several computers, like field service laptops, the locked serial number model lets you plug and play without having to worry about matching the two. Description Serialized Locked Serial Number Every unit is assigned a unique COM port - Same type model numbers shares the same COM port - Fixed Locations Field Service Ideal applications When ordering Locked Serial Number versions, add a "-LS" to the item number. Serialized and Lock Serial Number versions sell for the same price. 364 www.bb-elec.com | USOPTL4 & USPTL4_3713ds In-line USB Converters USOPTL4 & USPTL4 specifications Serial Technology RS-422/485 4-Wire TDA(-), RDA(-), TDB(+), RDB(+), GND RS-485 2-Wire DATA A(-), DATA B(+), GND Connector Terminal block Data Rate 460.8 Kbps Isolation 2 kV RMS Surge Protection 15kV ESD Industrial Bus Modbus ASCII/RTU Bias 4.7 K on receive lines in RS-422/485 mode USB Technology USB Compatibility 1.1 and 2.0 Speed 1.5, 12 Mbps Type B High Retention Connector (15 N / 3.4 lbs-force withdrawal) Windows 2000, XP (32/64 bit), Vista (32/64 bit), Operating System 7 (32/64 bit), 8 (32/64 bit), 2003 & 2008 Server (32/64 bit) Power USB Low power device (draws <100 mA) Indicators LEDs Transmit data, Receive data Mechanical Dimensions 8.9 x 4.3 x 2.1 cm (3.5 x 1.7 x 0.8 in) Enclosure IP 30, Plastic MTBF USOPTL4 311,327 hours MTBF USPTL4 1,012,584 hours MTBF Calc.
