4. Digital System Configurations
The typical digital system configurations are shown in Figures 4-1, 4-2, and 4-3. Figure 4-1 is a “full” digital sys-
tem. A full digital system includes a Temposonics II LDT with an integrated Digital Personality Module (DPM) and
a Digital Counter Card and supplies either a Binary Coded Decimal (BCD) or Natural Binary output. When
ordered as a scaled system, the components are matched and factory calibrated and will provide an exact, discrete
resolution.
Figures 4-2 and 4-3 illustrate other system configurations which use the output from either the Digital Personality
Module (DPM) or the RS422 Personality Module (RPM) as direct input into a control system. The DPM provides a
pulse duration output and the RPM provides an RS422 interface.
