Under normal operating conditions, the rear panel OBAM Out LED on one
SoundStructure device and the OBAM In LED on another SoundStructure
device will light solid green when a valid OBAM Out to OBAM In connection
is made as shown in the following figure.

If there is an invalid OBAM connection (OBAM Out to OBAM Out or OBAM
In to OBAM In), the OBAM status LED's will blink (0.5 seconds on, 0.5 seconds
off).
An OBAM cable may be tested by connecting the cable between the OBAM In
and OBAM Out ports on the same SoundStructure system. Depending on the
version of firmware, if the cable is functional, the OBAM In and Out LED's will
either blink 0.5 seconds on and 0.5 seconds off (version 1.2.0) or they will turn
solid green (version 1.2.1 and above). If the LED's do not light then either the
OBAM cable is not functional or there is an error with the OBAM interface on
the SoundStructure device.
Front Panel LED Status
If the linked SoundStructure devices do not have a previously loaded config-
uration file, the front panel lights on all the SoundStructure devices will be
solid green after the devices finish booting.
If the OBAM-linked SoundStructure master device has a previously loaded
configuration file that does not match the currently linked SoundStructure
devices, the front panel LED on all SoundStructure devices will turn solid yel-
low. The solid yellow LED indicates that the SoundStructure project loaded
into the master SoundStructure devices does not match the type and number
of devices in the overall SoundStructure system. The yellow light will turn
green once a valid configuration file is loaded into the SoundStructure system
as described in the Creating a Multi-Device Configuration File section.
A front panel LED that is solid YELLOW once devices are linked via OBAM and
powered up indicates that the system does not contain a compatible
SoundStructure configuration file that matches the number and type of
SoundStructure devices linked together. This condition may be corrected by
uploading a configuration file that matches the OBAM-linked SoundStructure
devices.
