3. Feed the
GSM/GPS
antenna cables
through the fitting
on the top of the
enclosure and
push the antenna
onto the enclosure
bulkhead.
4. Remove the mounting
plate from the back of
the modem. To
separate the two
pieces, push the
button on the top of
the modem, rotate the
plate slightly away,
and slide the mounting
plate downwards.
Be careful not to rotate
the plate too far or the
tabs on the bottom

7. Connect the GSM and GPS antenna cables to
the modem.
9. Connect the other end power cable and the RS232
to USB cables to Thiamis 1000 as shown.
8. Connect the power cable and the RS232 to USB
converter cable to the side of the DustTrak
photometer as shown.
10. Plug the AC/DC power supply into an AC power
source. Instrument and modem should power on.
11. The LED on the modem will blink while the modem
searches for a suitable network. If the LED stops
blinking and is solid blue, a network has been found
and proper communication with Environet™ should
be possible. If the LED changes to solid yellow, the
modem has not found a network. A power cycle may
resolve the issue or the unit may need to be moved
to a different location where signal strength is
improved.
