MULTI-RATE ETHERNET EXTENDER
10
Note
Actual distance and link performance may vary depending on the envi-
ronment and type/gauge of wire used.
Follow the steps below to connect the Ethernet Extender interfaces.
The Ethernet Extender units work in pairs. One of the units must be a Local (L),
and the other unit must be a Remote (R). It does not matter which end is the L
and which is the R. The link is always initiated by the Remote. As long as the
Local is powered on, the Remote can establish a link by being powered on or by
having its power reset.
1. To function properly, the two Ethernet Extenders must be connected
together using twisted-pair, unconditioned, dry, metal wire, between 19
(0.9mm) and 26 AWG (0.4mm). Leased circuits that run through signal
equalization equipment are not acceptable.
2. The Ethernet Extender is equipped with two interface jacks that can be used
on the
LINK
interface, an RJ-45 or a terminal block. These
LINK
interfaces
are a two-wire interface. Observe the signal/pin relationships on the
LINK
interface jacks.
The RJ-45 connector on the Ethernet Extender’s twisted pair interface is polarity
insensitive and is wired for a two-wire interface. The signal/pin relationship is
shown in Figure 3.
