CW (psinject) hardware injection excitations running on h1calex

Jim and Dave

To test the stability of the continuous wave psinject hardware injection, we restarted this program by hand on h1hwinj1. Note the autostart by monit did not work, which we tracked to an accidental activation (patch and/or reboot) of the local firewall blocking EPICS connections. For now we are not running CW under monit control, so if it were to stop it would not be restarted.

A reminder that the CW is an awgstream excitation of the H1:CAL-PINJX_CW_EXC exitation point (channum=25) on h1calex. This excitation is summed with the PCAL excitation signal and sent out via a DAC channel to modulate the PCAL laser.
