The Ariadne is a combination Ethernet and parallel port board. Physically, it is a 3/4 length card, with BNC and RJ45 connectors for 10BASE-2 and 10BASE-T Ethernet connections, and a female DB25 parallel port connector.
An internal 26-pin header provides a connection for a second parallel port, and four LEDs display connection information.
By default, the Ariadne auto-selects the type of Ethernet media based on what is attached. This can be overridden by setting an environment variable called Sana2/ariadne0.config to the preferred value (10BASET or 10BASE2). For example, to force the Ariadne to use the 10BASE-T connection:
��� setenv Sana2/ariadne0.config 10BASET
Remember that environment variables will only be saved if they are copied to the ENVARC: logical device.
The Ariadne software claims to support up to ten Ariadne boards in one Amiga (although which Amiga has this many slots remains unclear). Software is also provided to redirect printing to the Ariadne parallel ports. �
