Safety Warning
The i.LON 100 Internet Server telephone modem should be used only with
telephone circuits equipped with proper lightning and transient protection
circuitry. This minimizes the risk of shock or damage should lightning strike
on or near a telephone circuit to which the i.LON 100 Internet Server is
connected.
The RJ-11 telephone connector is used with i.LON 100 Internet Server Models
72102 and 72104. This connector must be used with a suitable male RJ-11
connector that is connected to a two-wire POTS connection that is compatible
with the V.90 internal analog modem. The i.LON 100 server analog modem is
not compatible with ISDN circuits.
CAUTION – To reduce the risk of fire, use only No. 26 AWG or larger
telecommunication line cord.
Screw Terminal Connectors
The screw terminals accept 0.34 – 4.0mm 2 (22 – 12AWG) gauge solid wire. The
optimum tightening torque for the screw terminals is 0.75mm (6 lbs. in.)
maximum. The ideal flathead screwdriver tip width is 3mm (0.12”). Wires
should be stripped to a length of 7mm (0.28”). Although not required, it may be
useful to use a soldering iron to tin the stripped lengths of any stranded wires to
prevent fraying and inadvertent contact with adjacent terminals.
The screw terminal connections can be divided into seven groups:
• RS-485/Serial ports.
