Frequency and Digital Output switch settings 79
3.5.2 Frequency and Digital Output switch settings
The meter provides two pairs of configurable frequency outputs (FO1A, FO1B, FO2A, and FO2B)
and four configurable digital outputs (DO1A, DO1B, DO2A, and DO2B). These outputs are
divided into two groups as follows:
• Group 1: FO1A, FO1B, DO1A, DO1B
• Group 2: FO2A, FO2B, DO2A, DO2B
The frequency and digital outputs are individually configured for “internally powered” mode or
“open collector” mode via CPU Board switch banks S8 and S9 (see Figure 3-25 and Figure 3-26).
See Section 2.4.4 for information on these modes.
