SERIAL CABLE DATA SHEET RN-SRL-PRO3V USB to 3-3V SERIAL UART Cable, Prolific Chipset Features Enables USB-to-Serial TTL conversion/bridging Connects to device (Microcontroller) UART or I/O Programmable baud rate generator can be configured to support data transfer rates from 75 to 12M baud at TTL levels I/O includes TX, RX, RTS, CTS, VCC, and GND USB 2.0 full speed compatible Supports 5,6,7 or 8 Data bits, 1, 1.5, or 2 Stop bits, and Parity setting of None, Even, Odd, Mark, or Space Parity error, Frame error, and Serial Bread Detection supported Data flow controlled by RTS/CTS, DSR/DTR, or XON/XOFF Configurable 512-byte Bi-Directional Data Buffer 256-byte out/256-byte in, or 128-byte out/384-byte in Internal EEPROM with allocated user writable area On-Chip One-Time Programming ROM for device start-up configurations PCB assembly powered by USB Bus External Logic powered from USB Port at +3V On-Chip USB1.1 Transceiver, 5V->3.3V Regulator Operating temperature range: -40C to +85C Zero-Cost Royalty Free Drivers and Virtual Comm Port Software Drivers (USB and DLL software interface) and Virtual Comm supports: W98, 98SE, ME, Win2K, Win2003, WinXP, Win2008, WinXP-64, Win7, Win7-64, WinVista, WinVista64, WinXP-Embedded, WinCE v4.2, v5.0, v6.0, MAC OS8, OS9, OSX, and Linux 2.4+ Available Length is 6-Feet (1.8 m) Available in either Black or Translucent USB connector shell overmold Description The RN-SRL-PRO3V is a USB-to-Serial TTL bridge cable available in Black or Translucent Overmold USB-A male connectors, having connection-ready 6 conductor tinned-leads at the opposite end. Each cable is made up to a 6 foot length (1.8m), with a heat-shrink finish treatment. At the core of each cable assembly is the RN-SRL-PRO3V USB-to-Serial TTL Bridge Board Module (PCB Assembly) designed to accommodate a quick and easy means to interconnect to devices having TTL level Serial interfaces which require conversion to USB.The RN-SRL-PRO3V cable assembly is assembled with a fixed TTL level of +3.3V, and is RoHS compliant. Deriving its power from the USB bus connection, the RN-SRL-PRO3V is USB 2.0 Full Speed compatible and inherently complies with all of the Prolific- PL2303HXD documented features and specifications. RN-SRL-PRO3V also includes support for data transfer rates of up to 12Mbaud and support and User Customizable Descriptors for OTPROM programming including User-defined serial numbers. This programmability feature is extremely useful in cases where security is an issue, and where password protection is required for applications involving file transfer processes and other security applications. Each RN-SRL-PRO3V (Translucent) is equipped with two LEDs preconfigured as data transmission activity indicators for the TX (RED) and RX (GREEN) signal lines. Support files and application utilities are available to redefine the fixed function purpose of either or both LEDs as desired. Software drivers are zero-cost and royalty-free and readily available from various online sources as well as from our support site: http://rovingnetworks.com/support.php 102 Cooper Court Los Gatos, California (408) 395-5300 info@RovingNetworks.com Page 1 of 4 RN-SRL-PRO3V SERIAL CABLE DATA SHEET RN-SRL-PRO3V Mechanical Details -Wire Descriptor Wire Descriptor Wire Color Connection Function Description Black GND GND Ground Supply Brown CTS# Input Clear to Send - Handshake Red Vcc Output +5V output Orange TXD Output Transmit Async Data Output Yellow RXD Output Receive Async Data Input Green RTS# Input Request to Send - Handshake Bare SHLD SHLD GND Shield Ground Operating Parameters Parameter VDD_5 IDD T Reference Output Power Voltage Output Driving Capacity Operating Temps.
