Group: Administrators Posts: 13K, Visits: 102K	Hmm, nothing normatively wrong w/ the script as far as I can see, BUT it sure can be greatly simplified. I've done that in the attached file -- perhaps it makes a difference. Other than that -- no clue. Can you take a screenshot of the Parallel Port Monitor settings that are confirmed to work and attach?

BTW, if you are looking for an example script re. TTL signals, see the Auditory Oddball Task available from the Task Library at the millisecond.com site.

Group: Administrators Posts: 13K, Visits: 102K	There are no obvious mistakes in the code snippets you posted. Also, defining a dependency ( via /select=current() ) is unnecessary given the way you have set your stimulus up -- one <port> element w/ a single item corresponds to exactly one <text> element w/ a single item. The interesting question is: Which settings did you use in the Parallel Port Monitor to get the devices to "talk to each other"? Do the /port, /subport etc. settings in your <port> elements properly reflect those settings? You must make sure they do, otherwise it won't work. Finally, as an alternative to sending 8-bit binary strings, sending integers should also work in current Inquisit 4 versions.

Group: Forum Members Posts: 6, Visits: 23	Hi, Thank you for your help so far. I've managed to get Inquisit talking to Acqknowledge via the parallel port test. My only issue now is that none of my stimuli are actually sending biomarkers to Acknowledge. I've tried looking for script templates to see if it's something wrong with my script, but I've only been able to find the one on the Inquisit manual. Could it just be a matter of the specific binary numbers I am using? I've tried several different ones and the issue is still not being resolved. Could you please take a look at my script to see if there are any mistakes that I'm not seeing? *********************************************************** TTL Parallel Signal ********************************************************* <port targetsignalwhite> / port = lpt1 / subport = data / items = ("00000000") /select = current (targetwhite) </port> <port targetsignalA> / port = lpt1 / subport = data / items = ("00000001") /select = current (targeta) </port> <port targetsignalB> / port = lpt1 / subport = data / items = ("00000010") /select = current (targetb) </port> <port targetsignalC> / port = lpt1 / subport = data / items = ("00000100") /select = current (targetc) </port> <port targetsignalD> / port = lpt1 / subport = data / items = ("00001000") /select = current (targetd) </port> <port targetsignalE> / port = lpt1 / subport = data / items = ("00010000") /select = current (targete) </port> <port targetsignalF> / port = lpt1 / subport = data / items = ("00100000") /select = current (targetf) </port> <port targetsignalG> / port = lpt1 / subport = data / items = ("01000000") /select = current (targetg) </port> <port targetsignalH> / port = lpt1 / subport = data / items = ("10000001") /select = current (targeth) </port> <port targetsignalI> / port = lpt1 / subport = data / items = ("10000000") /select = current (targeti) </port> <port targetsignalJ> / port = lpt1 / subport = data / items = ("10000010") /select = current (targetj) </port> <port targetsignalK> / port = lpt1 / subport = data / items = ("10000011") /select = current (targetk) </port> <port targetsignalL> / port = lpt1 / subport = data / items = ("10000100") /select = current (targetl) </port> <port targetsignalM> / port = lpt1 / subport = data / items = ("10001000") /select = current (targetm) </port> <port targetsignalN> / port = lpt1 / subport = data / items = ("10010000") /select = current (targetn) </port> <port targetsignalO> / port = lpt1 / subport = data / items = ("10100000") /select = current (targeto) </port> <port targetsignalP> / port = lpt1 / subport = data / items = ("11000000") /select = current (targetp) </port> *********************************************************************** Trials *********************************************************************** <trial trial1> / stimulusframes = [1 = targetWhite] / trialduration = 6000 </trial> <trial trial2> / stimulusframes = [1 = targetA, targetsignalA] / trialduration = 10000 </trial> <trial trial3> / stimulusframes = [1 = targetB, targetsignalB] / trialduration = 10000 </trial> <trial trial4> / stimulusframes = [1 = targetC, targetsignalC] / trialduration = 10000 </trial> <trial trial5> / stimulusframes = [1 = targetD, targetsignalD] / trialduration = 10000 </trial> <trial trial6> / stimulusframes = [1 = targetE, targetsignalE] / trialduration = 10000 </trial> <trial trial7> / stimulusframes = [1 = targetF, targetsignalF] / trialduration = 10000 </trial> <trial trial8> / stimulusframes = [1 = targetG, targetsignalG] / trialduration = 10000 </trial> <trial trial9> / stimulusframes = [1 = targetH, targetsignalH] / trialduration = 10000 </trial> <trial trial10> / stimulusframes = [1 = targetI, targetsignalI] / trialduration = 10000 </trial> <trial trial11> / stimulusframes = [1 = targetJ, targetsignalJ] / trialduration = 10000 </trial> <trial trial12> / stimulusframes = [1 = targetK, targetsignalK] / trialduration = 10000 </trial> <trial trial13> / stimulusframes = [1 = targetL, targetsignalL] / trialduration = 10000 </trial> <trial trial14> / stimulusframes = [1 = targetM, targetsignalM] / trialduration = 10000 </trial> <trial trial15> / stimulusframes = [1 = targetN, targetsignalN] / trialduration = 10000 </trial> <trial trial16> / stimulusframes = [1 = targetO, targetsignalO] / trialduration = 10000 </trial> <trial trial17> / stimulusframes = [1 = targetP, targetsignalP] / trialduration = 10000 </trial> <trial trial18> / stimulusframes = [1 = targetWhite] / trialduration = 3000 </trial> *************************************************************************** I've also tried the port script like this: <port targetsignalO> / port = lpt1 / subport = data / items = ("10100000") /select = picture.targeto.currentindex </port> But that was also unsuccessful.

I am unsure whether this is an issue with my script or the set-up of the port through the parallel port monitor. The first thing to do is check all the things I've mentioned (port number, etc.). > 3. I do not understand how to have a biomarker present in acqknowledge for each photo stimulus I present in inquisit I don't understand that question either. Are you asking about an issue w/ Acqknowledge? If so, you would have to take that up with their support. As for your Inquisit script, it will send the signals you specified in your various <port> elements out along with the various different <picture>s. And it will try to do so using the data register of LPT1, as you have specified. I would suggest you connect the Acqknowledge to your machine, set it to receive and then toy around with different settings in the parallel port monitor and see if you can get any signal across.
