FM Modular Splitter
FM modular splitters are used with modular adaptors and modular
cables. This splitter converts the 100-pin MEGAPORT 12FM board
connector to a set of 12 RJ-45 modular jacks. Figure 3-9 illustrates
devices connected to the MEGAPORT using the FM modular splitter.
The FM modular splitter (Equinox part number 990173)
converts the signals on the 100-pin connector to 12 RJ-45
modular jacks. This modular splitter is used to connect
the MEGAPORT board to ports requiring full modem
control.
10-wire modular cable must be used to attach devices to the
splitter.
Modular Cables
RJ-11 modular cable is the flat cable used for wiring telephones
inside of buildings. The cable is terminated at each end with an RJ-
11 modular plug (connector) which is inserted into the modular jack
of an appropriate wiring module. Standard modular cables available
from Equinox or wiring distributors are reversing; that is the pins
are reversed on each end (so that pin 1 on one end is connected to
pin 6 on the opposite end, etc.). Figure 3-10 illustrates the signals
passed through modular cables when connected to a CS port using
the Equinox part number 210016 CS modular splitter.
