Ethernet interface specifications

The base Stinger unit has an Ethernet interface that supports the physical
specifications of IEEE 802.3 and IEEE 802.14 with Ethernet 2 (Ethernet/DIX)
framing. The unit provides a single Ethernet interface, labeled ETNERNET 10BT, that
supports a 10BaseT unshielded twisted pair (UTP) cable with an RJ-45 connector.
The Ethernet address used to identify the Ethernet interface resides in the Stinger
MRT unit's motherboard.
STS-3 (synchronous transport signals-3) connector
specifications
Connection from the STS-3 connector on one Stinger MRT unit to an STS-3
connector on another unit requires a Category 5 crossover cable with RJ-45
connectors. The pin arrangement and wiring for both ends of a crossover cable are
described in Table C-3 and Table C-4.
