Here are some of the features of
the RB Series response boxes:
|
USB interface |
Compatible with Windows and Mac OS. Yes, it is even
compatible with Linux though we cannot provide support
to Linux users. |
|
Replaceable key tops |
Customize the response pads to any experiment (more
below). |
|
Built-in reaction time measurement |
Get peace of mind with a hardware timer that guarantees
1 millisecond resolution. Your computer is now free to
perform any task, however complex (e.g. playing a movie)
while the response pad takes care of timing (more
below). |
|
Universal compatibility |
The RB Series response pads are compatible with E-Prime,
Presentation, SuperLab, and other programs. |
|
No batteries or A/C adapter required |
Take them anywhere, they work even on a battery-operated
laptop. |
|
Accessory Connector |
You now have six general purpose TTL lines -- save on
the cost of an I/O card (SuperLab 3.0 will be needed to
take advantage of this feature). |
|
Upgradeable firmware |
Your response pad will never be obsolete. The firmware
(the software inside the pad) can be upgraded via a
simple download. |
Customizable Key Tops
 With
the RB-x30 models, Cedrus introduces removable key tops on all
models. The tops can be removed without any tool. Every model
includes red, green, blue, yellow, and clear tops.
This feature gives you, the investigator, new ways to
customize the response pad for your particular experiment.
Examples include using all four colored tops in a Stroop
experiment, or use the red and green tops to simplify
instructions to participants, e.g. "press the green key if the
two faces are the same or red if they are not".
You can even display your instructions, literally, on the
response pad. Using your printer, you can print any text or
graphic, on plain white or colored paper, and insert it under a
clear top.
The top of every key on every RB model can be removed and
replaced except for the round button on the RB-530.
Built-in Timing Facilities
The RB-x30 response pads are XID devices, or eXperimental
Interface Devices. This technology was originally developed for
the high end
Lumina
fMRI response pads but is now included in the RB Series pads as
well.
Being an XID device means that your response pad can measure
the participant's reaction in hardware and then report a time
stamped response to the computer. This capability relieves the
computer to provide computationally intensive trials such as
movies without worrying about maintaining accurate timing.
XID devices provide timing and other facilities, e.g. a
long-cycle timer that can be polled at anytime by the computer,
test procedures for measuring transmission delays due to the
computer's operating system, support for an Accessory Connector
(see below), and so forth.
RB Series Accessory Connector: Features, In Plain English
The Accessory Connector on the back of the RB Series response
pads provides up to six highly configurable I/O (input/output)
lines that can be used to send a signal to an external device or
to accept input from external sources.
Note: The features described below will require SuperLab 3.0
before you can take advantage of them.
The RB Series response pads sport an Accessory Connector that
can be configured in many ways and entirely via software. It can
function in one of two modes: Reflective or General Purpose.
When in Reflective Mode, the pins on the Accessory Connector
reflect the status of the response pad's push buttons. The
following options are offered:
| Reflective Mode |
When a Push Button is Pressed... |
| Continuous |
...the corresponding pin on
the Accessory Connector goes high and stays high until
the push button is released. |
| Single Pulse Mode |
...a single pulse is sent
on the corresponding pin. The pulse's duration can be
adjusted. This mode works well with many ERP systems. |
| Double Pulse Mode |
...a pulse is sent on the
corresponding pin; when the push button is released, a
second pulse is sent. |
Two additional features are available when in Reflective
Mode:
- A pin on the Accessory Connector provides an "OR"
output. It goes high when any push button is pressed.
- The logic of the output pins can be set to active high
or active low.
When in General Purpose Mode:
- The Accessory Connector can be used for general purpose
input/output (I/O) operations.
- Any I/O lines can be used for either input or output.
- Lines selected for input can be pulled high or pulled
low, entirely via software -- no exterior resistors needed.
- For input lines, inputs are time stamped.
