+**Step 1 - Configuring the computer hardware**\\
 Using CIGAL's **Settings** menu, select: **Configuration Settings**
-**Step 2 - Setting the software control variables**
+I recommend turning on the SRBox as device 2 (set order=2) to enable the scanner to trigger your tasks.
+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).
+If you want to record eye-position as well you can turn on the eyetracker (order=4).
+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**\\
 Using CIGAL's **Settings** menu, select: **Hardware Settings**
-**Step 3 - Verifying physiological transducer signals**
+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**.
