NTI SERVER ENVIRONMENT MONITORING SYSTEM

GSM Modem Connection

If alert notifications via SMS to a cell phone are desired, a GSM modem can be connected to the male 9DB DTE port labeled
"AUX". Using this serial connection, a user can receive SMS alert messages directly on their cell phone.
modem can be either self-powered or connected to 12V from the ENVIROMUX using the "AUX PWR" terminal.
ENVIROMUX is a DCE serial device.
GSM modems that have been tested and are confirmed to be compatible with the ENVIROMUX include:
Note: The GSM modem must be connected to ENVIROMUX and powered ON before powering ON the ENVIROMUX.
Note: The "AUX PWR" terminal is backed up by the battery inside ENVIROMUX.
WARNING
Device connected cannot
exceed 150mA contact
load.

Cascaded Installation via Direct Connection

For a cascaded installation using the Direct Connect method (see page 19), enabling the monitoring of all sensors from up to four
ENVIROMUX-SEMS-16 systems, connect a CAT5/5e/6 patch cable (maximum 25 feet long) with RJ45 male connectors on each
end (wired straight thru, pin 1 to pin 1, pin 2 to pin 2, etc.) between the "In" and "Out" ports as shown in the image below.
this properly connected the user can monitor the sensors of all systems from either a single connected terminal (page 13) or
through a single Web Interface (page 21).
