I’ve got a problem using my cedrus response box (rb830) with Inquisit3. I installed the driver from the homepage and now wanted to test it. I used the seriell port monitor (implemented in Inquisit 3) to check whether I receive correct signals from the response box and I get them only for 6 of 8 keys. The keys top left and top right don’t send signals (probabely they should send the scancodes 64 and 128 - because the others send 1, 2, 4, 8, 16 and 32).
First I thought that there is something damaged in my box, but meanwhile I tested seven different boxes and I get the same problem for all of them.
I found another interesting fact. I used the command “/inputdevice = xid1” instead of “inputdevice=com1”, changed the positions of the DIP switches appropriately and then checked the box with the port monitor again. Now all keys sent signals (so the two keys are probabely not damaged) but I got the same signal from all eight keys.
Could the drivers be responsible for that, or does anybody else have an idea what’s happening?
p.s. I set the baud rate to 9600 and I put the DIP switches 1,2,3 upward as described in the instructions (http://www.cedrus.com/support/rb_series/tn1044_dip_switches.htm)
p.p.s. I encounter the same problem using Inquisit2, too
