Sensor Attachment

Note: It is very important to locate the temperature and/or humidity sensors away from ventilation sources and fans.
1. Connect each external sensor having an RJ45 male connector on it (ENVIROMUX-STS, ENVIROMUX-SHS, ENVIROMUX-
STHS, ENVIROMUX-LDS) to one of the female connectors labeled "RJ45 Sensors" on the ENVIROMUX. Male connectors
should snap into place.

Note: If the ENVIROMUX-LDS Liquid Detection sensor is installed, the twisted orange sensing cable should be placed
flat on the surface (usually the floor) where liquid detection is desired. If tape is required to hold the sensor in place, be
sure to only apply tape to the ends, exposing as much of the sensor as possible.
exposed for it to function. (See Figure 5)
2. Some sensors do not have RJ45 connectors on them
and instead have terminal blocks. These can either be
connected to the "DIGITAL IN" connectors or they can
be terminated and plugged into the remaining RJ45
connectors (see Figure 6). (The illustration uses CAT5
patch cable to make cable connection easy.) Examples
of these sensors include ENVIROMUX-IMD,
ENVIROMUX-IMD-MW, ENVIROMUX-EMD-CM,
ENVIROMUX-VSS, ENVIROMUX-SDS, and
ENVIROMUX-GBS. ( For more on these and other
sensors, see pages 2 and 3.)
Note: For sensors requiring 5VDC power source,
substitute the wire connected to pin 4 (see page 73)
instead of pin 7.
See page 72 for wiring specification and pinout.

Note: Shielded cable is
required between the
sensor and the ENVIROMUX
to maintain CE compliance
of the sensor.
