Table 6D (below) identifies the terminations to make with the positive and negative interrogation lines
(Pin 9 and 10) depending on the Temposonics II configuration being used in your application. It is impor-
tant note that when using a “neuter” version Temposonics II, DO NOT connect both the positive and neg-
ative interrogation leads at the same time — the unused lead must be tied to ground.
Table 6D Temposonics II Interrogation Configurations
Transducer Pin No. Functional Description Personality Module Interrogation Mode
9 (+) Interrogation Neuter Temposonics II, Temposonics II w/RPM
10 (-) Interrogation or Temposonics II w/DPM (external interrogation, See Note)
9 (+) Interrogation Neuter Temposonics II (positive interrogation), Temposonics II w/RPM
10 DC Common or Temposonics II w/DPM (external positive interrogation)
9 DC Common Neuter Temposonics II (negative interrogation), Temposonics II w/RPM
10 (-) Interrogation or Temposonics II w/DPM (external negative interrogation)
9 DC Common Temposonics II w/DPM (internal interrogation)
10 DC Common Temposonics II w/APM (all modes)
Note:
1. It is recommended that both the positive and negative interrogation leads be connected when using a Temposonics II with a DPM (external
interrogation ONLY). This will provide a differential interrogation signal which is preferred over a single ended interrogation.
6.3 Digital Counter Card Connections
See Appendix A of this manual for an in-depth explanation on how to specify systems with digital output.
Tables 6E, 6F, and 6G show the counter card output connection tables. In order to select the proper table,
the following order variables must be known.
Stroke: inches (mm)
Resolution:
inches (mm)
Recirculation:
(1 - 127)
Output Format:
BCD or Natural Binary
Output:
Latch Pulse (standard: 1µs, optional: 12 µs)
Input:
Latch Inhibit (Standard)
