Digital input data port (power sense port)
An input voltage below 1.2 VDC is considered to be logic low. An input voltage above 1.2 VDC is considered to be logic high. These thresholds are not adjustable.

Firmware version, part number & information requests
Query firmware version number Q or 1Q Q or 1Q
X11
Show the MLC’s firmware version (
X11
)
to two decimal places. This query yields the number of the currently running version of the user-updatable firmware.
Example: 1Q 1Q 1.01
Query verbose version information 0Q 0Q
{response from 2Q}–{response from 3Q}–{response from 4Q}
Show the bootstrap, factory-installed, and updated firmware versions. See 2Q, 3Q, and 4Q below.
Example: 0Q 0Q 1.03-1.00(1.18-MLC104 -Thu, 20 Jan 2005 09:41:47 GMT)-1.00*(1.18-MLC104

Query bootstrap firmware version 2Q 2Q
X11
The bootstrap firmware is not user-
replaceable, but you may need this information during troubleshooting.
Example: 2Q 2Q 1.03
Query factory firmware version 3Q 3Q
X11
(kernel version–model description–date time of upload)
Factory-installed firmware is different from the bootstrap firmware, but it is also not user- replaceable. This firmware was installed at the factory; it is the version the controller reverts to after a mode 1 reset (see chpt. 2).
Example: 3Q 3Q 1.00(1.18-MLC104 -Thu, 20 Jan 2005 09:41:47 GMT)
In this example the factory firmware version is 1.00 and the IP Link kernel version is 1.18 for the MLC 104, dated 20 January 2005.
