MODULE DATA SHEET RN-SRL-PRO3V-DGL USB to 3V Serial UART dongle, Prolific drivers Features Enables USB-to-Serial TTL conversion/bridging Description Connects to device (Microcontroller) UART or I/O Programmable baud rate generator can be configured to The RN-SERIAL-PRO3V-DGL is a USB-to-Serial TTL support bridge board module (PCB Assembly) designed to Data transfer rates from 75 to 12M baud at TTL levels accommodate a quick and easy means to interconnect to I/O includes TX, RX, RTS, CTS, VCC, and GND devices having TTL level serial interfaces which require USB 2.0 full speed compatible conversion to USB. The on-board bridge controller is the PROLIFIC 64-bit PL2303HXD USB to Serial UART Supports 5,6,7 or 8 Data bits, 1, 1.5, or 2 Stop bits, and device which controls the relevant USB signal and protocol Parity setting of None, Even, Odd, Mark, or Space requirements. Parity error, Frame error, and Serial Bread Detection supported As a PCB Assembly, the RN-SERIAL-PRO3V-DGL is Data Flow controlled by RTS/CTS, DSR/DTR, or comprised of 2 main components, a USB type-A connector XON/XOFF as the interface to the outside world and small form factor Configurable 512-byte Bi-Directional Data Buffer256- PCB requiring soldered-wire connections to the mating byte out/256-byte in, or 128-byte out/384-byte in device(s). The RoHS compliant PCB assembly is Has internal EEPROM allowing with allocated user configured with a fixed TTL output level of +3.3V. writable area On-Chip One-Time Programming ROM for device start- Deriving its power from the USB bus connection, the RN- up configurations SERIAL-PRO3V-DGL is USB 2.0 Full Speed Compatible PCB assembly powered by USB Bus and inherently complies with all of the Prolific External Logic powered from USB Port at +3V PL2303HXD documented features and specifications. The On-Chip USB1.1 Transceiver, 5V->3.3V Regulator RN-SERIAL-PRO3V-DGL also includes support for data Operating Temperature range: -40C to +85C transfer rates of up to 12Mbaud, and supports User Zero-Cost Royalty Free Drivers and Virtual Comm Port Customizable Descriptors for OTPROM programming Software including User-defined serial numbers. This Drivers (USB and DLL software interface) and Virtual programmability feature is extremely useful in cases where Comm supports: security is an issue, and where password protection is W98, 98SE, ME, Win2K, Win2003, WinXP, Win2008, required for applications involving file transfer processes WinXP-64, Win7, Win7-64, WinVista, WinVista64, and other security applications. Each bridge board module WinXP-Embedded, WinCE v4.2, v5.0, v6.0, MAC OS8, is equipped with two LEDs which are preconfigured as data OS9, OSX, and Linux 2.4+ 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: MODULE DATA SHEET RN-SRL-PRO3V-DGL Mechanical Details PAD Location and Signal Description Ordering Information Part Number Description RN-SRL-PRO3V-DGL USB to 3V serial UART dongle, Prolific chipset, USB connector, bare PCB 5V serial connection Related Products Part Number Description RN-SRL-FTD5V-DGL USB to 5V serial UART dongle, FTDI chipset, USB connector, bare PCB, 3V serial connection 102 Cooper Court Los Gatos, California (408) 395-5300 info RovingNetworks.com Page 2 of 3 RN-SRL-PRO3V-DGL
