Additional description
Firmware version, part number and information requests
N
In a query response, an asterisk (*) after the version number indicates the version that is currently used.
A question mark (? or ?.??) indicates that the factory default firmware is the only firmware loaded in the MLC.
A carat (^) indicates the version of firmware that should be running, but, since a mode 1 reset was performed, the factory default firmware version is loaded and running instead.
An exclamation point (!) indicates that the firmware is corrupted.
N
Responses to commands differ depending on which, if any, verbose response mode the MLC is in. See the CV command (

) under IP setup commands later in this
table.
Query firmware version number Q or 1Q Q or 1Q
X1! ]
or Ver01*
X1! ]
Show the MLC’s firmware version (
X1!
)
to two decimal places. This query yields the
number of the currently running version of
the user-updatable firmware
Example:
1Q 1Q 1.01
or Ver01*1.01
Query verbose firmware version information
0Q 0Q
{response from 2Q}–{response from 3Q}–{response from 4Q}

or Ver00*{
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 2.16-1.00(1.57-MLC104IP -Wed, 16 Jan 2003 00:00:00 GMT)-1.01*(1.65-

Query bootstrap firmware

The bootstrap firmware is not user-
replaceable, but you may need this
information during troubleshooting.
Example:

Query factory firmware version 3Q 3Q

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(1.57-MLC104IP -Wed, 16 Jan 2003 00:00:00 GMT)

In this example the factory firmware version
is 1.00 and the IP Link kernel version is 1.57
for the MLC 104 IP Plus, dated 16 January
2003.
