GET Run control (old way)

DESCRIPTION

These programs initiate (daqstart) and terminate (daqstop) data taking in a CoBo. The assumption they make is that some outside agency, such as GetController has prepared the CoBo for data taking with the desired configuration.

hwnode describes the service on which the desired CoBo is accepting connections. This is given in ip-address:service-number format where ip-address is the dotted IP address of the CoBo and service-number is normally 46001.

eccserver describes the service on which the GET eccserver is accepting connections. This should be given in ip-address:service-number where the ip-address is the address of the host system (spdaq) on the 10Gbit private subnet that connects the host to the microTCA crate. The service-number is normally 46002.

You can determine the proper IP addresses for a CoBo by examining the /etc/dhcp/dhcpd.conf which determines which physical ethernet addresses are given which IP addresses. You can determine the proper IP address for the Ecc Server by issuing the command

/sbin/ifconfig -a
            

And examining the IP address of the last ehternet interface. For example; in spdaq08, the command above will give the following output:

See the emphasized part of the eth5 output. The IP address is 10.50.200.2.

The final, optional, parameter for daqstart controls whether or not the internal pulser is started. For pulser tests, this must be 1 (the default). For ordinary data taking (e.g. with external triggers), this should be 0. This is required because GetController e.g. does not turn on the test pulser until its Start button is clicked.

Note that daqstop unconditionally turns off the test pulser so that if the next run does not explicitly turn it back on, the pulser will remain off.
