Setting The Baud Rate - Valon 5009a Operation Manual

can type 5000term -S <serial_num> where <serial_num> is the serial number of the 5009. You
can find the serial number of the 5009a by using the ID or STATus command. There serial
number will appear as shown:
Valon Technology, 5009, 12201623, version 1.0
Any other terminal program should also work well, however 5000term.exe will automatically
detect the 5009 and configure the virtual serial port. A list of available commands appears in
section 4.
Figure 2 5000term.exe terminal program provides a convenient method of direct synthesizer control using simple
commands.
Links to our GUI and terminal program are shown below in the Quick Start section 2.0.
Also available is a direct 3.3V TTL serial interface at the USER PORT. This allows the same
command set to be sent directly to the ARM processor from a host processor without requiring
any USB connection. This port can also be used with the optional external RS-232 to TTL serial
adapter. This 3V TTL/CMOS port is also 5V tolerant. For more information on this port, see
section 5.
The default baud rates are 9600 for the USB port and 115200 for the USER PORT. Either port
can be set to 9600, 19200, 38400, 57600, 115200, 230400, 460800, or 921600.

1.5 Setting the Baud Rate

The USB port baud rate can be changed using the baud command as in "baud 115200" which
changes the synthesizer baud rate from the default value of 9600 to 115200. However, once the
baud rate has been change it will be necessary to exit the terminal program using "ctrl C"
because communication will no longer be possible. To reestablish communication, restart the
terminal program with the corresponding baud rate. When using 5000term.exe, the command
would be "5000term -r115200. Note: If you want the baud rate to persist after power down,
use the SAVe command.
