Connect Sensors
Connect the desired sensors (sold separately) to the available ports on the ENVIROMUX. Plug the RJ45 connectors to either of
the two RJ45 ports marked "TEMPERATURE/HUMIDITY". Mount the sensors according to their individual operating
characteristics. Power-cycle the ENVIROMUX after sensors have been plugged-in.
Note: The maximum CAT5 cable length for attachment of temperature and humidity sensors in the
ENVIROMUX-MINI-LXO is 25 feet.
Note: Mounting the temperature sensor in the path of a fan or on a heated surface may affect the accuracy of the
sensor’s readings
.

Sensors
Up to five dry-contact sensors can also be connected. Sensors with 16-26 AWG connection wires, that operate on 5V at 10mA
maximum current may be used. A contact resistance of 10k
Ω
or less will be interpreted by the ENVIROMUX
as a closed contact.
The maximum cable length for attachment of contact sensors is 1000 feet.
To install the dry-contact sensor(s) to “DIGITAL IN” terminals:
A. Attach the positive lead to a terminal corresponding to a "+" marking on the ENVIROMUX and the ground lead
to the next terminal to the right that will correspond to a marking on the ENVIROMUX. Tighten the set
screw above each contact. Terminal sets are numbered 1-5.
B. Mount the sensors as desired.

Note: The terminal block is removable for easy sensor wire attachment if needed.
