Installation

Description
The MMX-MOD3 module is intended to be installed inside a protective enclosure.
This minimizes the effects of the environment contaminating the BNC jacks or
the pc board, and assures better data collection. CTC offers our MMX1000/2000
Series Enclosures for this purpose.

Electrical Connections

The orientation of the removable plugs has BNC #1 with plug closest to the DIN
rail mount (or bottom) on the module, with #2 in the middle and #3 will be nearest
the BNC's. This configuration provides an easier method of wiring the module
when placed inside an enclosure.

Setup of DIP switches

The MMX-MOD3 modules can be setup to provide grouped signals from a dual
output sensor, or a triaxial style sensor that share the "common" conductor.
By adjusting the switches, the common connection can be shared between
inputs 1 & 2, 2 & 3, for dual outputs and between inputs 1, 2, & 3 for triaxial
sensors. This system eliminates the need to insert jumper wires between the
different inputs within the module. The switches are displayed in Figure 2 at the
center of the module, on the circuit board.
