WARNING
Failure to use specified cables may result in damage to the SCC board(s).
Token Ring Connection
The Token Ring Interface cable can be attached directly to the Token Ring Media
Access Unit (MAU), or can be extended by attaching it to another cable that is
attached to the MAU. The unit attachment point is at the TRC board using a 9-pin
D connector.
Ethernet Connection
10/100 Mbps Ethernet
The single RJ-45 connector on the network cable supports 10 Mbps or 100Mps
speeds. NWAY auto-negotiation enables the 10/100Mbps Ethernet NICs to
automatically run at the speed that the connected hub supports. The 10/100 Mbps
Ethernet NICs works with products that comply with IEEE 10BASE-T and 100
BASE-TX specifications.
10BASE-T Operation
10BASE-T is the Institute of Electrical and Electronics Engineers (IEEE) 802.3
standard for Ethernet signaling over unshielded twisted-pair wire at 10 Mbps.
Ethernet, as the most widely used network protocol, uses 10BASE-T as its primary
cabling scheme. Ethernet’s characteristics include:
• A data rate of 10 Mbps.
• A broadcast architecture.
• A specific media-access control (MAC) scheme.
The 10BASE-T name indicates a signaling speed of 10 Mbps and twisted-pair wiring.
Base stands for baseband, which denotes a technique for transmitting signals as direct-
current pulses rather than modulating them onto separate carrier frequencies.
