    help // to get a list of options when using the command line interface
+Some general commands:
+  * **scanccu** : returned the list of the connected CCUs
+  * **scanringedevice** : scan all the connected electronic devices and addresses (ccu, dohs, pohs, ... )
+  * **scanpixeldevice** : summary of the connected and missing devices (no addresses list)
+  * **delay25 init** , **pll init** , **doh init** : initialize the devices
+To check pohN response (N = 1,2,3,4,5,6,7):
+  * first set the ccu to which the poh if interest is connected doing for example : **ccu 0x7e**
+  * set the channel of the poh of interest (0x13 for L34 and 0x11 for L12) doing for example: **channel 0x11**
+  * **pohN read** : read the values of the 4 channels bias and gain (b0, b1, b2, b3, g0, g1, g2, g3)
+  * to set the bias or the gain do for example: **pohN set b0 30**
+  * to set all the values at the same time do for example: **pohN set all 3 3 3 3 0 0 0 0**
+  * to init the poh settings: **pohN init**
+To test i2c speed:
+  * first set the ccu: **ccu 0x7b**
+  * set the channel (0x13 for L34 and 0x11 for L12): **channel 0x13**
+  * set the i2c speed: **i2cspeed 1000**
+  * NB: the programmable i2c speeds are 100,200,400,1000 kHz
+====Test Programs====
 Run the test program (from a different terminal):
    cd TriDAS/pixel/BPixelTools/
@@ Line 18: / Line 43: @@
    cd test
    python testCCUandDCDC.py <ccuaddress>
+Run the test program for POH bias scan at a specific gain
+  * open a terminal and run the ccu program
+  * open a second terminal and run the fed program
+  * open a third terminal for the test program:
+   cd TriDAS/pixel/BPixelTools/
+   source setup.bsh
+   cd test
+   python testCCUFED.py --gain <gain>
+  * the results are stored in the testdata folder (create one if it does not exist)
+Additional macro to plot the poh bias scan results in the folder "macros" under the test dir
+  * be sure the input files are called "poh_bias_scan_gain<gain>.root"
+  * if you want to compare the bias/rms/slope of different channels at fixed gain <gain>
+   python make-plots.py --gain <gain> --plot bias
+   python make-plots.py --gain <gain> --plot rms
+   python make-plots.py --gain <gain> --plot slope
+  * if you want to compare the bias/rms/slope of one channel <channel> for different gain values
+   python make-plots.py --channel <channel> --plot bias
+   python make-plots.py --channel <channel> --plot rms
+   python make-plots.py --channel <channel> --plot slope
+====Analog FED====
+Start the server:
+   cd TriDAS/pixel/BPixelTools/fed
+   source setup.bsh
+   ./run.bsh
+Check that addresses are set correctly in fed/data/fed_parameters.dat and fed/data/fed.ini
+====pxFEC====
+Start the server:
+   cd TriDAS/pixel/BPixelTools/pxfec
+   source setup.bsh
+   ./run.bsh
+Some commands:
+  * **exec data/d.ini** : program the module (N.B: the settings in the d.ini file are loaded automatically when starting the server)
+  * **cn +2PL12** : set control network (+2PL12 for layers 1-2 and +2PL3 for layers 3-4)
+  * **module 31** : set the module hub
+  * **roc 0:15** : set the ROCs you want to program
+  * **Vana 120** : program the ROCs registers (ex: Vana)
+  * **tbm reset** : reset the tbm
+  * **tbm disable triggers** (**tbm enable triggers**) : force no token passed mode (the tbm does not wait for the token to be returned)
+  * **tbm enablepkam** (**tbm disablepkam**) : the tbm is reset after a lapse of time in which it does not receive the token back
