- Page 2 1.6. The DSP-CA module is simply a junction box without switching. One of each module is required to interface the cable to the DSP Modules. Note: A DSP-CAS can be used instead of a DSP-CA if necessary, but the input terminals would have to be permanently shorted.
- Page 3 Failure to observe these precautions may result in death or severe personal injury. 2.1. The DSP-CA(S) modules may be connected to the DSP Feeder Modules DSP-DFM by the use of either of the two ribbon cable connectors from either side as desired. See Figure 2.1 (a) and (b) 2.2.

There should be no continuity (2 Megohms, or greater) when there is no short across terminals 1 and 2 of the DSP-CAS and when shorted there should be low resistance between the two terminals (less than 100 ohms).
