DIP
switches 1–4 on the inside edge of the printed circuit board are used to
inform the micro computer of changes in setup in the hardware selection
jumpers (see Figure 13). Each channel has 3 switches to represent the
thermocouple type or millivolt measurement that is performed.
NOTE: The ON position is selected by pushing the switch toward the center
of the printed circuit board.

Locate
the hardware Thermocouple Compensation Jumpers corresponding
to input channels 1 through 16. These jumpers are located adjacent tothe
input terminal strip (see Figure 13). For each input channel, select either
millivolt input or thermocouple type by placing the jumper in the correct
position.
Locate JP68 on the printed circuit board to select PLC Login Mode (see
Figure 13). Standard login is 16WX registers in the PLC. Advanced
Operating Mode logs in as 16X, 16Y, 32WX and 32WY registers. Consult the
SIMA
TIC 255x Sixteen Channel Advanced Function Programming
Reference Manual, part #62–177, if the advanced operating mode is to be
selected.
Locate SCALE jumper JP69 on the printed circuit board. (See Figure 13.)
Select Engr to present data to the PLC as temperature X10 or Millivolt
X100. Select SCALE to scale and present data as an unsigned integer from
0–32000.
