Bbox Button Box - TDT RZ2 Manual

BBOX Button Box
BBOX Overview
The button box is a complete subject response interface. It is an excellent system for
psychoacoustics, including n-alternative forced choice, GO NO GO, Bekesy style
presentation, and modified method of limits experiments. The button box provides
accurate reliable performance. All inputs are debounced in the button box and a
built-in rechargeable lithium-ion battery provides power for up to 24 hours of
continuous use per charge.
The standard button box configuration includes six buttons and six high intensity
LEDs. However, the button and LED organization can be configured to user
specification. The button box can have up to eight buttons and 32 LEDs. The button
box design allows experimenters a great deal of flexibility to control feedback based
on subject response, reinforcing behavior for correct and incorrect choices.
The button box can be controlled from an RP2.1 or RV8 processor with button
response acquisition and LED control through the digital input/output port of these
modules. Data can be latched and then read from specialized RPvdsEx circuits using
ActiveX and Matlab, or other programming languages. RPvdsEx circuits designed for
button box control can be used with all TDT software.
Connecting the Button Box to the RP2.1 or RV8
The button box is controlled using the RP2.1 or RV8 processor. The button box
connects from the DB25 connector (Control) directly to the digital input/output port
on the RP2.1 or RV8 with the supplied ribbon cable. The button box is configured
at the factory for the RP2.1. It can be configured for the RV8 by installing a jumper
pin (Jumper for RV8) on the back of the button box.
