 ===== Recording physiological signals in real-time=====
-ShowPlay is designed to automatically record a variety of behavioral variables during any real-time paradigm.  Behavioral recording is controlled by a few standard control variables. For recording physiological signals such as heart-beat or repiration you must have appropriate physiological transducer hardware installed and connected to your computer. Once enabled, physiological signals are recorded throughout every ShowPlay paradigm without any modification to the paradigm itself.

 Recording physiological signals involves 3 steps:

 **Step 1 - Configuring the computer hardware**\\
-Using CIGAL's **Settings** menu, select: **Configuration Settings**
+At the BIAC scanners, the default **sysconfig.imp** file automatically initializes:
+  * graphics - the display screen, keyboard, mouse, and most USB response boxes
+  * srbox - the EPrime Stimulus/Response box (also used for reading the scanner trigger signal)
+  * meascomp - the Measurement Computing analog/digital box (used for all Biopac physio i/o)
+  * eyetracker - connection to 2nd computer to read Viewpoint eyetracking signals\\
+If those are all the devices you need you do not need to change the configuration.
-I recommend turning on the SRBox as device 2 (set order=2) to enable the scanner to trigger your tasks.
+If you do want to use different hardware devices, use CIGAL's **Settings** menu to create a customized hardware initialization file, which will be named "userconfig.imp" in your current folder.
-Physiological signals (cardiac, respiration, GSR) are analog voltages converted to digital values by the Measurement Computing Analog/Digital converter box.  You must therefore configure CIGAL to initialize the MeasComp box (e.g. set order=3 for meascomp).
+To change devices, select:  **Settings -> Configuration Settings**\\
+To turn on or off a device, set the initialization Order value (first col). Set to 0 to not use.\\
-If you want to record eye-position as well you can turn on the eyetracker (order=4).
+Each device will have several parameter options, which should default to optimal values.
-On BIAC6, the **userconfig.imp** file I typically use has these lines:
-  srbox 1 - 5
-  meascomp 0 8 - - - - - - 2
-  eyetracker 3
 **Step 2 - Setting the software control variables**\\
