4-2 IETG FlowHawk Manual
EMUX enables the RTU to obtain real-time monitor data
through a serial connection and the Profile software (a user) to
communicate with the monitor through a wireless connection.
Direct, on-site communication with the monitor is possible through
an IS serial connection between the monitor and a laptop computer.
This chapter contains information and instructions on the following:
 Installing the GSM module in the manhole
 Installing the communication cable and the EMU outside the
manhole near the external power source
 Installing the communication cable and the EMUX outside the
manhole near the RTU and/or external power source
 Connecting directly to the monitor on site
Note: Manhole and sewer system work involves confined
space entry and is inherently dangerous. Therefore,
installers and technicians must comply with all national,
state, and municipal regulations concerning confined space
entry. IETG are not responsible for any injuries, damages,
claims, or liability resulting directly or indirectly from the
use of this installation guide or the installation of any
IETG equipment.
Warning: The GSM Module requires connection to an
external antenna. Only antennas provided by IETG are
approved for use. The user must maintain a distance of
229 millimeters (9 in) from the antenna whenever the
modem is in operation.
