We added a new channel C3:PSL-FSS_FREQCOUNT which contains the analog output of the SR620 frequency counter connected to the beat photodiode.

• C3:PSL-FSS_FREQCOUNT is connected to CH6 of the first 3123 card, connector P3 (first D-SUB). This is also J4 of the PSL x-connect.
• Added channel entry in fss.db database. Sampling rate is 10Hz.  Scaled from -10 to 10V in unit  "volts" as we don't know which settings we will use later.
• Also added channel to daqd. restarted daqd. Manual restart of daqd as controls using script requires password for controls.
  That shouldn't be so but i was to lazy to search for the bur

Counter output is 0 to 8V, right now used in relative mode which means zero frequency deviation equals 4V. Current gain for first test is 100kHz/V.
