Repeaters
Repeaters are mainly used to switch network topologies but do not regenerate the signal; therefore,
repeaters are more limited by wiring distances. Signal degradation is a factor to consider when
utilizing repeaters. The repeater option for Intelligent Fire Integrator™ is the 4WRMB. A
ROUTMB must be used to separate (installed between) 4WRMB from a subsequent 4WRMB
when such routing exists on Echelon networks.

1.4.2 Router Options For Intelligent Fire Integrator™ Systems
The routers listed here allow you to connect Echelon network segments isolated by great distances
that cannot be spanned by conventional wire media.
ROUTMB The ROUTMB is a field programmable, protocol regenerating, intelligent router. It
allows transparent passage of network messages between two network segments of the same or
different types. ROUTMBs must be used to separate 4WRMB from a subsequent 4WRMB on an
Echelon network. Available network formats are wire and optical fiber.
NCB-EL Communication between two NCB-EL routers is via an Ethernet-to-Lonworks
connection that uses standard CAT 5 Ethernet cross-over cable.
NCB-FL Communication between two NCB-FL routers is via an Ethernet Fiber-to-Lonworks
connection that uses dedicated fiber optic wire runs.
NCB-IM The communication channel between these routers can be any analog or digitized analog
channel capable of supporting V.32 turbo standard modem signalling, including standard dial up
public switched telephone circuits, 2-wire or 4-wire leased lines or dry copper CAT 5 cable (dry
copper mode uses leased-line configuration over shorter distances). Data transfer between routers
is delayed only by the transit time through the routers and telephone networks.
