Subject: New Acromag units for AWC experiments - XT1221 ans XT1541 

I set up an Acromag DAC today with the fixed IP address 10.0.1.56. Last Friday Andrew and Antonio set up an ADC unit with fixed IP address 10.0.1.55. The former is for outputting a control voltager that goes to the driver for the heater on composite mirror we are testing. The latter is used to read the temperature of the thermocouple on the composite mirror. The thermocouple to voltage conversion is achieved with a Type K Thermocouple Amplifier unit from The Sensor Connection.

The temperature sensor channel is C4:AWC-TEMPMON_C. We took a couple of different measurements of temperature and calibrated the conversion from volts to Celsius as: C = 122.06*V -0.67

The new temperature sensor channel is now being recorded in the frames.
