Port Descriptions

10Base-T,RJ-45 port (Series 90-30 Ethernet Interface (10Base-T Type), Series 90-30 CPU364, and Series 90-70 IC697CMM742 Ethernet Interface (Type 2))

The 10Base-T port uses a twisted pair cable of up to 100 meters in length between each node and a hub or repeater. Typical hubs or repeaters support 6 to 12 nodes connected in a star wiring topology.

Auto-sensing 10 Base T / 100 Base TX, RJ-45 Port (Series 90-30 CPU374 only)

The auto-sensing 10 Base T / 100Base TX ports are connected to a switch device embedded in the Ethernet Interface. They use a twisted pair cable (unshielded or shielded) of up to 100 meters in length between the node and another node, a hub, a repeater, or a switch. The port automatically senses the speed (10Mbps or 100Mbps), duplex mode (half duplex or full duplex) and cable (straight-through or crossover) attached to it with no intervention required.

10Base2, BNC port (Series 90-70 Ethernet Interface (Type 2))

The 10Base2 port uses a 0.2 inch diameter 50-ohm coaxial cable and is commonly called “thin wire”. The maximum length of a cable segment is 185 meters. A maximum of 30 stations is allowed on a 10Base2 Ethernet segment.

AUI Port (Series 90-70 Ethernet Interface (Type 2)) and

AAUI Port (Series 90-30 Ethernet Interface (AAUI-only Type) and Series 90-30 CPU364)

The AUI and AAUI ports provide the electrical and mechanical interface to the user-provided Ethernet transceiver cable, which connects the AUI or AAUI port to an external user-provided transceiver. (The transceiver cable may be separate or built-in to the transceiver.) The external transceiver is directly connected to the Ethernet cable.
