For this connection, you can use:

HP 92264D (1-meter ThinLAN AUI extension, pin 4 not connected)

HP 92254A through H (6-meter through 48-meter ThickLAN cables) HP 92254J (5-meter ThinLAN AUI cable, pin 4 not connected)

Some longer cables may have all 15 pins wired. See the IEEE 802.3 standards document for definitions of the pins not shown here.
