Echelon i.LON 10 Ethernet Adapter - Manual (Page 26)

Connecting The i.LON 10 Ethernet Adapter to a Modem
You can connect the i.LON 10 Ethernet Adapter to an analog, GSM, or ISDN
modem using a standard DB-9 – DB-25 straight though modem cable.
You must use a straight through modem cable to connect the i.LON 10 to
the Modem. A crossover cable will not work.
In order to for a modem to communicate with the i.LON 10, it must support all of
the following signals: Tx, Rx, GND, RTS, CTS, DSR, DTR and CD. Check with
the modem manufacturer to confirm that the modem you want to use supports
these signals.
Configuring the i.LON 10 Ethernet Adapter for PPP
The i.LON 10 Ethernet Adapter supports three methods of establishing
communication using a modem attached to its serial port:
• Dial-out – The i.LON 10 Ethernet Adapter can be configured to use an
attached modem to dial-out to an ISP. Once connected to an ISP, a
connection to an LNS Server on an attached TCP/IP network can be
established.
• Dial-in – The i.LON 10 Ethernet Adapter can be configured to use an
attached modem to accept incoming calls.
• Shoulder tap – The i.LON 10 Ethernet Adapter can be configured to listen for
an incoming call, then dial-back in response. This allows you to call the
i.LON 10 from a remote location and have the i.LON 10 respond by calling an
ISP that is local to it, thus avoiding toll charges and providing security. The
i.LON 10 Ethernet Adapter cannot simultaneously support the dial-in and
shoulder-tap methods.
