Figure 7: Left side right angle header pinout
Figure 7 shows the pinout of the header on left side of the EL9803
’s top. Depending on the selected
process data interface, the definition of the pins PDI4 and PDI6 to PDI9 are differing. The pin names
given here are based on the ET1100 PDI pinout. Thus detailed information about pin description and
electrical specification of these pins can be found in the ET1100 Hardware Data Sheet that can be
downloaded from the company’s website. An overview of the pinout is given in the following table.
