These external transceivers can run at interface bit rates from 9.8 kbps to 1.25
Mbps.
A complete router, using the Router 5000, consists of two Router 5000 half
routers, two transceivers, and a motherboard to connect the two half routers, as
shown in Figure 3 .

As the figure shows, two Router 5000 half routers and two transceiver modules,
one to handle each of two channels connected by the router, can be mounted on a
motherboard, along with a single power supply and two network connectors.
This sub-assembly constitutes a L
ON
W
ORKS
router. It can be packaged in an
enclosure to meet unique form factor and environmental requirements.
Depending on the application, the package could contain a single router sub-
assembly, or could include other application-specific hardware. Multiple routers
can be packaged together for some applications, such as a backbone connecting
multiple channels.
Unlike an RTR-10 router, you store the L
ON
W
ORKS
transceiver parameters for
each Router 5000 half router in external EEPROM, thus allowing you to define
the appropriate transceiver type for each side.
