Using the SSR-1U
The SSR-1U default configuration sets all channels to 115200 baud, 8 data bits, no parity, and
1 stop bit. Channels 1-3 are configured to record when DI is pulled low. Channel 4 is
configured to present the user shell.
On power up, the SSR-1U displays a boot loader announcement and device details. If a channel
is attached to the user shell, it will present the user shell prompt. A typical power-on sequence
would produce output similar to:
Details of the shell interface are provided in Section 4 Interactive Shell. As an example of shell
usage, consider changing the command source for channel 3 to
+dig
so that the device records
when the DI pin is high. In the following sequence,
<enter>
means pressing the Enter/Return
key to execute the command in the shell. With the SSR-1U shell connected to a terminal
program, type
config
<enter>
to show the current SSR-1U configuration.
To change the command source for channel 3 to
+dig
, type
config 3 src +dig
<enter>
Verify that the configuration has been changed using:
config 3
<enter>
To save the modified configuration in on-board non-volatile memory so that it is preserved
across power cycles, type:
config save
<enter>
To confirm that the configuration has been saved, reboot the SSR-1U and verify configuration
using:
reset
<enter>
config
<enter>
Note that ‘cfg’ is an alias for ‘config’ and can be used as a shortcut.
