2.5 Analog Sources – Table 2.2
Sources can be either analog or digital.
Analog sources are identified within a math block by the preset mnemonic shown in Table 2.2.
2.6 Digital Sources – Table 2.3
Up to three digital signals, identified within the Math Pad as md1, md2 and md3, can be used within each math block. These signals
must be assigned to a digital source from Table 2.3 prior to selection within the math pad.
