1. Getting Started
1.1 Overview
DataBridge SDR2-USB serial data recorders record RS-232 serial data to
industry-standard mass storage using an Microsoft Windows™-compatible
FAT file format. The SDR2-USB is equipped with a USB 2.0 socket and is
designed for use with USB storage media such as USB flash memory keys.
During Record mode, the SDR2-USB’s data port accepts RS-232 serial data
from your data source. The SDR2-USB data port supports baud rates up to
921600 bps and RTS/CTS hardware handshaking for reliable high-speed
communication. Your SDR2-USB is also equipped with a real-time clock,
power-saving features, non-volatile memory, and a resume-on-power failure
feature. The SDR2-USB features a one-button front panel user interface
that starts and stops recording.
SDR2-USB configuration is performed by editing a setup file on the USB
storage device.

1.2 Before you start
Before you start, be sure you have the following items available:
•DataBridge SDR2-USB
•A 5-30VDC power supply
•RS-232 DB9 serial cable
•The device you wish to record from (serial data source)
1.3 A quick guide to the DataBridge
SDR2-USB
On the front of the SDR2-USB are the USB "A" socket, record button, and
LED indicators. The SDR2-USB can be toggled in and out of record mode
using the record button located on the front panel. The LED indicators
show the SDR2-USB’s current recording status. The data indicator flashes
when data is received and is used to verify data reception from your data
source.

NOTE: Your
computer’s Windows
installation may
display different drive
letters, file types, etc.
due to differences in
Windows versions,
configurations, and
software installations.
On the rear is the male nine-pin D-subminiature connector (DB9M) for the
data port. The 5 to 30 VDC power input is also located on the rear panel.

1.4 Deploying the DataBridge SDR2-USB
1.4.1 Connecting power to your SDR2-USB
The SDR2-USB starter kit includes a 120VAC power supply that connects
via the rear panel. If you use an alternate power source, it should be capable
of sourcing at least 1W power. When you apply power the power indicator
should light and the other indicators should flash in sequence.
1.4.2 Configuring your SDR2-USB via the setup file
To successfully receive data from your data source, the SDR2-USB must
know at which baud rate the data source is transmitting. Configure the
recorder for this baud rate using the setup file.
Insert the USB device you intend to use for recording into your PC’s USB
socket. Usually, Windows will respond by displaying the contents of the
device. If this doesn’t occur, navigate to the device’s drive letter (e.g. J:).
Right-click within your drive’s contents in Windows Explorer, then select
“New” and “Text Document.” When prompted, name the file setup.txt
(See Figure 1.3).

Figure 1.3. Creating setup.txt.
Once the file is created, double-click it to open the file in Windows Notepad
and enter “DataPortBaud=9600” as shown in Figure 1.4. This tells the
SDR2-USB to communicate with your data source at 9600 baud. The baud
rate for your serial data source may differ from 9600 bps.
Figure 1.4. Editing a simple setup.txt file.
Close Windows Notepad, then right-click the USB device’s drive letter and
click “Eject” to safely remove the device from your system.
Insert the USB device into the SDR2-USB, connect your serial data source
to the DB9M connector, and connect power. The SDR2-USB will display a
left-to-right-to-left flashing sequence. If your data source is outputting data,
the front panel “data” indicator will flash as data arrives.
1.4.3 Congratulations!
You’ve set up the SDR2-USB to communicate with your device!
