the host. This should force the i.LON 10 to dial-out. Watch the modem LEDs
for activity and listen for dial tone, ringing, and connection:
• If the modem LEDs do not flash, the i.LON 10 is probably not
communicating with the modem.
• If the LEDs flash, but the modem doesn’t dial:
i. Set Modem Init String on the PPP Configuration Web page to “&F”.
This will reset the modem to its factory defaults.
ii. Check that the RS-232 line speed is the same as you used when
testing the modem with the computer.
iii. If you have the LonTalk® Protocol Analyzer available, confirm that
an attempt was made to send a packet from the L ON W ORKS network
to the host. If no attempt was made, assure that the Initiate
Session when… option set in step 4 is set appropriately for the
network variable being updated.
• If the modem dials, but no connection takes place, confirm that the port
numbers specified on the General Setup Web page are open on the ISP
and the computer with the LNS Server.
• If everything appears to be configured correctly, check the Event Log
page for errors.
