I am using a TTL device and need DirectRT v.2006 to record reaction time based on responses from that device. The device sends signals of 120 and 248, as indicated using the Empirisoft Port Read/Write Test. Everything works fine when I only ask DirectRT to "listen" for 120, however, when I enter 248, DirectRT asks for a joystick. I have been sure to include the port information, such that under the time column I have: rt:120,(889) -which works- and rt:248,(889) -which does not work. After looking at the key codes, it appears that DirectRT uses 248 as a joystick code. How can I get around this?
Thanks!
