The “LAVA Device Info” Utility
This utility is used to verify the firmware version and settings of an eSynC, LAVA eSTS, or
STS-RBM product. Installation of this utility is optional.
Pressing SCAN FOR DEVICE is used to check for a LAVA device and then report the device
information.
The ENABLE TIMEOUTS button enables the 7-minute recovery timeout. This button is
presented after a device is detected and the timeouts are currently disabled.
The DISABLE TIMEOUTS button disables the 7-minute recovery timeout. This button is
presented after a device is detected and the timeouts are currently enabled. Disabling the
timeouts permits the LAVA product to function without LAVA Tablet Manager being installed.
LTM is generally configured to restore these timeouts for reliable operation with LTM.
The RESTORE DEFAULTS resets the board to the manufacturing defaults. The
Power
Watchdog
and
Keep Alive Timeouts
are disabled as a manufacturing default. This button is
presented after a device is detected and the firmware version includes the required support. The
RESTORE DEFAULTS is not available in all product versions.
The eSynC and eSTS products have an internal 2-pin jumper labeled MODE. When this jumper
is installed, the extended features of the product are disabled, and the product cannot be detected
by this utility. The jumper is installed when the mobile device is not going to use LTM. With the
jumper installed, there are no timeouts to deal with. The factory default does not install this
jumper. Therefore, the extended features are active as the factory default.
With the timeouts enabled, the LAVA board is expecting messages from LTM. If no messages
are received within the timeout period, all attached USB devices are briefly disconnected and
reconnected every 7 minutes in an attempt to force LTM to run. As of late 2018, all LAVA
devices are shipped with the timeouts disabled as a manufacturing default. Disabling the
Timeouts with this utility is useful when LTM is not being used and it is not convenient to install
the 2-pin MODE jumper.
There are two generations of eSynC product. The original generation of products is reported as
“L”, and is also referred to as the “L Mk1”. The second generation of
products is reported as “L Mk2”.
The utility must be used with caution when LTM is installed on the mobile device. No harm can
be done by running to two applications, however, note that LTM can also modify the Timeouts
settings.
Note: The LAVA-Device-Info utility and is a useful addition for LTM 3 users. However, it is
redundant for users of LTM v4.** and v5.** as its features are now built into the app.
