The numbering of the KS-1992 Isothermal Termination Panel runs from 1 through 36, left to right. In two cables these inputs serve as an input to the KS-3516 Scanning A/D unit. This module is located in the TOFp CAMAC crate at position 9. Apart from the thermocouples, the isothermal panel also monitors the three threshold voltages actually being used on the FEE at three locations: in the TOFp tray and in each of the two pVPDs. The 28 temperatures and 3 threshold read-back values are thus digitized and archived for every experimental event with the TOFp and pVPD pulse area and timing information.
Note that the KS-1992 has 36 input channels, and the KS-3516 has 32 input channels, so four KS-1992 inputs are not used (see below). Note also that Channel 1 of the isothermal panel is internally wired to a reference thermocouple which is located inside this unit. This means that any signal cable wired to that input will not be read out. This behaviour is controlled by a switch on the rear of the KS-1992 unit.
In the table below, Ch 1992 refers to the location of the ThermoCouple (TC) wire pair at the (36 input) front panel of the KS-1992, and Ch 3516 refers to the Channel number of the TC at the (32 input) front panel of the KS-3516.
