I type this...
hex 24 base ! <string on label> EZ0G - hex .
... exactly (with spaces?), then type...
<hostid> 27b00 + .
...to get the MAC numbers? I can try this out on my LX...
Here's W for that code table...
W --..--.-.-.-
...or...
(Using _ for one and xx for two, the above becomes)
W xxxxxx______
Here's my barcodes, maybe easier to use this way...
X = width 1 bar
XX = width 2 bar
- = width 1 space
-- = width 2 space
| = width 1 space. Used to visually seperate the letters.
AUSY | A | U | S | Y |
X--X-XX-XX-X|XX-X-X--X-XX|XX--X-X-X-XX|X-XX-X-XX--X|XX--X-XX-X-X|X--X-XX-XX-

Same visual description...
- = space
-- = double space
1 = single width bar
2 = double width bar
