The DLC-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 DLC-SRL-PRO3V-DGL 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 DLC-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 DLC-SRL-PRO3V-DGL is USB 2.0 Full Speed compatible and inherently complies with all of the Prolific-PL2303HXD documented features and specifications. DLC-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 DLC-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.
