 ===== 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.
+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.
+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.\\
+Each device will have several parameter options, which should default to optimal values.
 **Step 2 - Setting the software control variables**\\
 Using CIGAL's **Settings** menu, select: **Hardware Settings**
+Turn on the data channels you want to record. These are typically **digio**, **keybd/mouse**, **cardiac**, **respiration**, and **eye-position**.  The channel numbers should be correct by default.
+For a list of all hardware and channel connections at the BIAC scanners check [[biac:experimentalcontrol:inventory|Device Inventory]].
+To record efficiently on the MeasComp box, click the **analog scan sampling** box **On**.
 **Step 3 - Verifying physiological transducer signals**\\
 Using CIGAL's **Display** menu, select: **Show Behavior** and then choose **Real-time values**.
