Introduction
The Thin Net (Cheapernet) module provides a complete
Local Area Network interface for a station, without a
transceiver cable. The EM2C is an encased module
containing all circuit components for a complete Thin Net
COAX interface and includes an on-board SEEQ CMOS
83C92C transceiver DC/DC converter and solation trans-
former.
The module is compatible with ANSI/IEEE 802.3 and ISO
8802-3.
The module is part of a chipset manufactured by SEEQ
Technology to provide the basic components for a LAN
interface board. The other components include the
80C03, 8005/80C04A Advanced Ethernet Data Link Con-
trollers (AEDLC
TM
), the 8020 or 8023A Manchester Code
Converter (MCC
TM
), and the 80C24 Media Interface
adapter (MIA).
Features
