Description
The RN-SERIAL-PRO3V-DGL is a 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 on-board bridge controller is the
PROLIFIC 64-bit PL2303HXD USB to Serial UART
device which controls the relevant USB signal and protocol
requirements.
As a PCB Assembly, the RN-SERIAL-PRO3V-DGL is
comprised of 2 main components, a USB type-A connector
as the interface to the outside world and small form factor
PCB requiring soldered-wire connections to the mating
device(s). The RoHS compliant PCB assembly is
configured with a fixed TTL output level of +3.3V.
Deriving its power from the USB bus connection, the RNSERIAL-PRO3V-DGL is USB 2.0 Full Speed Compatible
and inherently complies with all of the Prolific
PL2303HXD documented features and specifications. The
RN-SERIAL-PRO3V-DGL also includes support for data
transfer rates of up to 12Mbaud, and supports 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 bridge board module
is equipped with two LEDs which are 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
