6.2 Connection through GPRS gateway
When using a GPRS gateway, please follow the procedure below to connect Chaf-
folink to internet.
1. Power on the gateway and press the ON/OFF button. For few minutes the ga-
teway performs its startup procedure, during which all LEDs will fl ash a blue se-
quence. At its conclusion, the WEB led remains off, while the BUS (and SERIAL,
depending on the installation") remains on.
2. Once the procedure is done, the WEB led will show the strength of the GPRS
signal as follows
a. Steady blue Ð Max signal strength
b. Flashing blue Ð Medium strength
c. Flashing red Ð Low strength
d. Steady red Ð No line
Note: we suggest to place the gateway so that the Max intensity of the GPRS
signal is reached. Moreover, it is possible to use the external antenna kit, provided
by Chaffoteaux (code 3318892).
3. Press and hold the start-up button until the WEB led starts to fl ash a green light:
the gateway is now trying to SRAmatically connect to the Chaffoteaux server.
4. If the procedure has been successful, the WEB led will remain green and the pro-
cess is complete
Note:
in case of failure (WEB led red), repeat the above procedure starting from
point 3.
Important:
please begin the previously described procedure once the gateway has been
linked to the thermoregulation accessories through the BUS protocol, other-
wise the gateway won't be able to connect to internet.
