INSTALLATION AND SETUP
CONNECTING THE M4RTUXCAB
CABLE TO THE M4RTU/M4 I/O BASE UNIT
The optional M4RTUX I/O Extender Unit expands the number of input/output points available to the M4RTU/
M4 I/O from eight digital and four analog to 16 digital and eight analog.
If you plan to install the M4RTUX, you should attach the connecting cable (the M4RTUXCAB, packaged with the
M4RTUX) to the M4RTU/M4 I/O before mounting the base unit. You can then elect to mount the extender unit
right away or at some later time.
Brief procedures for connecting the M4RTUXCAB cable are provided below, along with a diagram illustrating
where the cable should be attached. For complete details on installing the M4RTUX, see Modular Controller
I/O Extender Data Sheet (form 671).
1.
Locate the I/O Extender connector. This 25-pin D-shell connector can be found on the same end of the
M4RTU/M4 I/O as the power supply connector.
2.
Align the M4RTUXCAB connector with the I/O Extender connector on the base unit and seat properly.
3.
Tighten the M4RTUXCAB connector locking screws to secure the cable to the base unit.
