DATA SWITCHING APPLICATIONS
In Venus DM 400B data switching applications, the switcher input table is used to assign a logical name to each physical port
connected to a “tributary” device. See Figures 5−38 and 5−39.
Note: Configuration of DM 400/400A Data Matrix boards is described in Appendix L.

Logical Input
Similarly, the switcher output table is used to assign a logical name to each physical port connected to a “controller” device.
See Figure 5−40.
Note 1: All port numbers that reside in the Switcher Output table must also have an entry in the Switcher Input
table (This is done to avoid possible Status display problems and is checked by the PC compiler).
