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 ? Another possibility is that the 1.02 firmware doesn't have the same status responses (there is a cryptic note in the X-Rite documentation for 1.03 saying "Added new status codes for supporting simple-strip mode"). If this is the case then I might have to change the way that a read chart is detected. cheers, Graeme Gill.
