#### Multiple P201 boards
Multiple P201 boards can be configured in Spec; each board requires an independent
entry in the SCALERS controller list. By default a board is configured as master and
started independently. CT2 masters are started sequentially (from last to first in the
config) so there is an intrinsic (accumulative) delay in their synchronization. A
better synchronization is obtained, as explained before, by connecting the output
channel of a master to the trigger input of the slave(s). The relation master/slave
must be explicitly indicated in the config of each slave controller through the
*master*
parameter. To access the controller parameters go the
*

, move the cursor on top of the SCALER slave controller and
type 'p'. Then add the
*master*
parameter and set it to the Tango device name
(controller ADDR) of the master device:

The definition of the timer of each P201 board (channel 0) is optional. It is
recommended to set the main (first)
*timebase*
counter as a CT2 timer. This
configuration will allow that all the CT2 masters count for the specified time. Even if
the main timer can be a
*Software Timer*
and different CT2 boards can be configured
as independent masters, each CT2 board will be stopped as soon as the
*Software Timer*
finishes, resulting in shorting and non-deterministic counting intervals.
