Specifications

The NR1001 is an external MAU (Media Attachment Point) that provides a 10BaseT interface for an AUI port. The device enables a AUI port node to be connected to a Ethernet LAN. Unit provides automatic polarity correction for receive.

Power

Powered from  the AUI connector. DC Power Source per ANSI/IEEE STD 802.3 2002

LAN Performance    

Meets performance, functional and interface requirements of ANSI/IEEE STD 802.3, 2002 for 10BaseT transceivers with receive mode collision detection.

Collision Detection

Detects collisions on LAN in both transmit and receive modes

SQE   

Generates a Signal Quality Error (SQE) test signal after completion of each transmission to  ensure collision circuitry is properly functioning.

AUI Connector 

15 pin “D” type Male Connector P/N C-24308/4-2.
