Step # Action to be Taken
4f Get ACT/BYP status code (ACT)
Desired status = Active
ACT bit = 1
4g Get SNG/DIF configuration code (DIF)
Desired Configuration = Single
DIF bit = 0
4h Get I/O coupling code (DC)
Desired coupling = AC
DC = 0
4i Get decimal Pre-gain code
Decimal gain code = (gain - 1) x 20
Desired Pre-gain code = 2.30
Decimal Pre-gain code = (2.30 - 1) x 20
Decimal Pre-gain code = 26
4j Get Pre-gain code (PRE7 - PRE0)
Convert decimal Pre-gain code to an 8 bit binary number
26 = 00011010 = PRE7(MSB) - PRE0(LSB)
4k Get decimal Post-gain code
Decimal gain code = (gain - 1) x 20
Desired Post-gain code = 10.05
Decimal Post-gain code = (10.05 - 1) x 20
Decimal Post-gain code = 181
4l Get Post-gain code (PO7 - PO0)
Convert decimal post-gain code to an 8-bit binary number
181 = 10110101 = PO7(MSB) - PO0(LSB)
Table 5.10 shows a summary of Step 4. Using the formulas for R, F, and Gain code given in the previous sections,
we can calculate the binary numbers for this configuration that are to be inserted into the format of Table 5.6.
