SDR2-CF/SDR2-OEM-CF Configuration Guide rev 1.0 Configuring the DataBridge SDR2-CF

NOTE: By default,

the SDR2-CF uses a

serial data format of

eight data bits, no

parity, and one stop bit

(8N1). Most serial

devices use this

format.

2.2 Configuring the data port

Before the SDR2-CF and your data source can communicate, they must

interact at the same data rate and using the same data format.

The SDR2-CF's data port is, by default, configured to communicate at

115,200 bps.

If your data source can communicate at 115,200 bps (also referred to as

115,200 baud), it may be easiest to configure it for 115,200 bps. For devices

with a fixed data rate, you will need to set the SDR2-CF's data port baud

rate to match your data source. You may also wish to choose a higher data

rate (and hardware handshaking) if your data source sends a high volume of

data.

Hardware handshaking ensures that the SDR2-CF sends messages only

when the data source is ready to accept them. Likewise, hardware

handshaking prevents a data source from sending data when the SDR2-CF

is not ready to receive it.

Be sure that your serial data source and the SDR2-CF use the same

handshaking settings. If the SDR2-CF monitors the handshaking signal but

your data source does not send it, the SDR2-CF will wait indefinitely for

"permission" to transmit messages. Likewise, if your data source monitors

the handshaking signals but the SDR2-CF doesn't send the appropriate

signal, the software may never transmit output data.

To change the baud rate for the data port, press 9, then press B and type the

desired baud rate (e.g. 115200). To change handshaking or data format, use
