10Base2 Port
The IC697CMM742 Series 90-70 Ethernet Interface (Type 2) is equipped with a 10Base2 port for
direct connection to a 10Base2 (thin wire) coaxial cable network, without addition of an external
transceiver. The 10Base2 port on the Ethernet Interface is connected to the 10Base2 network
cables by a BNC Adapter (female, male, female, in either “T” or “F”configurations).
Your 10Base2 network cables and connectors must meet the applicable IEEE 802 standards.
Information in this section includes 10Base2 port pinouts and cable diagrams.
