Hi Daniel,<br>
<br>
we use a Cedrus RB series device (the 540 in our case). Using the
XID mode - built-in timer reset via stimulus PC - and the correct
driver settings for the USB-to-Serial interface (USB
latency/timeout, baud rate) it is ok for human responses. I
encountered an average of 2 ms delay introduced by the serial
commands to the box.<br>

<p class="MsoNormal">We are currently using response devices
from curdes.com but have been having issues with button
presses being registered and sent to our stimulus software
(STIM) resulting in around 5% omissions. We purchased a
Logitech Gamepad F310 and, using the driver software, bound
keyboard responses to the bumper buttons on the back. Using
this device our omission rate is now 0% but there seems to be
around a 40ms timing difference between using the curdes
devices and the Logitech gaming pad (where the Logitech event
is delayed). I am not sure if this 40ms timing delay is due to
the driver software that needs to recode the input to the
assigned key press or if the increased latency is from the
Logitech device itself.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Does anyone have any suggestions as far as
response devices go and has anyone used the Logitech device
before?
