I am having a first stab at using the Argylle software for an Epson r2400 and an x-rite DTP20 spectrometer, which unfortunately is 1.02 formware so I have to use it untethered.

I first created a target with 'targen -v -d 9 -f 540  ./k3_540_1a4'
Then produced (and printed with gimp) a target as 'printtarg -v -i 20 -t -p A4 -C k3_540_1a4' and then subsequently scanned this chart with the untethered DTP20.

The DTP20 read the chart without problems and I am now trying to read the DTP20 stored patches with 'chartread -v ./k3_540_1a4' but there seems to be a problem recognising the chart.

Can't use saved spots because they don't match chart

Hi,

There seems to be a problem with how you read the chart.

dtp20: Sending '00GM^M'response '19^M<00>^M' ICOM err 0x0
dtp20: Sending 'CS^M'response '01^M<00>^M' ICOM err 0x0
dtp20: Sending '00GM^M'response '19^M<00>^M' ICOM err 0x0
Can't use saved spots because they don't match chart

This indicates the problem. There appear to be 19 individual
spot readings in the instrument, but no read chart.
(the response to the CS command will be 3 if there is a chart
in the instrument. Instead it returned 1, which indicates a
normal "instrument ready").

Did you clear the instrument before reading the chart ?
Did you successfully read the TID and then the strips ?

cheers,
        Graeme Gill.
