Inquisit code with EEG Cedrus Stimtracker

Hello,
I have five conditions in which participants passively view the stimuli while connected to an EEG Cedrus Stimtracker.  How do I flag each individual condition on the EEG recording?  Also, how do I add the stimtracker as an input to the Inquisit code?  I've looked at the stimtracker example but am having a hard time with building the code.  I have copied/pasted the only code I have for the stimtracker for your reference:

<xid stimtracker>
/ product = stimtracker
/ items = (1, 2, 3, 4, 5)
/ pulseduration = 58
/ select = stimulusname(bafaceitems, bifaceitems, wafaceitems, wifaceitems, objectitems)
/ selectionrate = always
/ erase = true
</xid>

<values>
/ response = 0
</values>

<data>
/ columns = [response latency]
</data>

<text productid>
/ items = ("Product: <% xid.stimtracker.product %>")
/ position = (5%, 70%)
