The 120ft cable H2:TCS-HWS_EY_CAB13 was strung between the D1200168 Beckhoff breakout box situated above the in-air ALS table (first picture) and the D1100682 EtherCAT Chassis in the CDS high bay (second picture). Thomas and I tested the pin-outs and confirmed that there was approximately 115 Ohms across pins 1 and 20 and pins 2 and 21 from the first 4-wire RTD and roughly 120 Ohms across pins 3 and 22 and pins 4 and 23 from the second 4-wire RTD on the in-air table. This cable was plugged into the back of the EtherCAT chassis in the TCS/Hartmann Sensor slot. 

When the TwinCAT System Manager software is fired up for this EtherCAT chassis, we can see the temperatures for the two sensors reported in Terminal "H2 End Station 2 L16 (EL3202-0010)" in channels 1 and 2, approximately 20.90C and 31.86C, the table and Hartmann sensor camera temperatures, respectively.
