The module has several options that you can select by installing or removing
jumpers. At the rear of the module is a bank of eight jumpers. They may be
configured to select either 16 Input Mode or 32 Input Mode operation, input range
selection, units of measurement selection and the number of channels enabled.

NOTE: If you are replacing a D4–04AD module with the F4–04AD in an existing
application, skip to the special section at the end of this chapter, "Configuration
Cross-Reference, D4–04AD to F4–04AD".
By default, the module arrives from the factory with all jumpers installed. With all
jumpers installed, the module has four active channels, is in 32 Input Mode, has 4 to
20 mA. input range, and the units of the data are 12-bit (0 to 4095) BCD numbers.
The F4-04AD module accepts from one
to four analog inputs and converts the
signal(s) to a desired format to send to
the CPU. The bottom two jumpers (J7
and J8) select the number of channels
enabled. The module only converts
signals on channels that are enabled. If
your application requires less than four
signal inputs from this module, selecting
fewer channels results in faster update
times.
Use the following table to set jumpers.
