SDR2-CF/SDR2-OEM-CF Configuration Guide rev 1.0
Configuring the DataBridge SDR2-CF
21
Initialization:
Some devices “wake up” or begin continuously sending data
only after receiving a specific command, the initialization string. When
prompted, press
Y
to indicate that the SDR2-CF should send the message
once when it enters record mode. This feature can be used together with
output interval to both initialize a device with a specific message and send
the message periodically. This is useful for resetting or automatically
reinitializing a data source if its power is lost. Entering
N
disables this
feature.
Stop:
In some applications you may wish to send a message to an attached
device when your SDR2-CF stops recording. When prompted, press
Y
to
indicate that the SDR2-CF should send the message once when it leaves
record mode. This feature can be used to power down or put a device to
sleep, or tell the data source to stop sending data while the SDR2-CF is not
recording.
Carriage return and line feed:
When prompted, enter
Y
to instruct the SDR2-
CF to add a carriage return and/or line feed to the end of a message. Many
devices require a carriage return and/or line feed after a message, while
others may require neither. Your data source’s documentation can help you
determine whether carriage returns and/or line feeds are required after query
strings.
Figure 2.11. Configuring message zero for output every 10
seconds and append carriage return and line feed.
The main configuration menu includes an option (menu option
4
) for
globally enabling or disabling output messages. Be sure output messages are
enabled when using the messaging feature.
