RDM devices can be configured through the web interface (only partially complete) or from the command line.
Device Discovery
The ola_rdm_discovery tool displays the UIDs found for each universe.
$ ola_rdm_discover -u 1 414c:010014b3
Passing the -f options will force the discovery algorithm to be run for the particular universe. This won't produce any output unless and error occurs.
$ ola_rdm_discover -u 1 -f
Device Configuration
The ola_rdm_get and ola_rdm_get commands allow attributes of the devices to be controlled. The first thing to do is to view a list of all known attributes:
$ ola_rdm_get --list_pids boot_software_version_id boot_software_version_label capture_preset clear_status_id comms_status default_slot_value device_hours device_info ...
To fetch the value of a PID from a device use:
$ ola_rdm_get --universe 1 --uid 414c:010014b3 device_info
Changing the value works in a similar way:
$ ola_rdm_set --universe 1 --uid 414c:010014b3 comms_status # clear the communication counters
The full list of options can be found by running with --help:
-d, --sub_device <device> target a particular sub device (default is 0) -h, --help display this help message and exit. -l, --list_pids display a list of pids -u, --universe <universe> universe number. --uid <uid> the UID of the device to control.
Useful Tricks
If you're using bash, it's worthwhile to set up tab completion of PIDs:
$ complete -W "$(ola_rdm_get -l | xargs)" ola_rdm_get $ complete -W "$(ola_rdm_get -l | xargs)" ola_rdm_set
