2. Ethernet Interface Versions
The TR515EX is designed to attach directly to the RJ45 10BaseT Ethernet
connector. Standard magnetics circuitry (YCL part 20F001N) has been included
onboard to provide a "glueless" interface to the Ethernet network.
Most Ethernet installations require cables of substantial and variable length,
so you will probably need to make your own cables. For testing purposes
PROMAG supplies two kinds of Ethernet cables: device-to-hub (WAS-1499) for
connections through a standard Ethernet hub, and device-to-device (WAS-1498)
for connections without a hub (i.e. directly from one Ethernet device to another).
