NOTES:
1. T1 is a 1:1 pulse transformer, with an inductance of 30 to 100µH.
2. IN916 or equivalent for Ethernet, not required for Thin Ethernet.
3. 78Ω resistors not required if AUI cable is not used, i.e., local transceiver.
4. Typical pull-down resistors are not required for either 10BASE2 or 10BASE5 application. Remove them for minimum current consumption.
5. Install 200kΩ to disable the 400ms collision announcement when disconnecting cable.
