The DESVA Ethernet controller option module enables the connection of a VAXstation 2000 or MicroVAX 2000 system to an Ethernet network via a ThinWire connection using RG-58 coaxial cable. The option is packaged on a 4-inch by 7-inch board that is located in the system unit and plugs into the two DESVA option connectors (J5 and J14) on the system module. The DESVA module is powered by the system box power supply. The DESVA contains a Local Area Network Controller for Ethernet (LANCE) chip, a serial interface adapter (SIA) chip, and a ROM that contains device-driver programming, and supports logic circuitry. The Ethernet transceiver chip, Ethernet address ROM, and the BNC connector for the RG-58 cable to the Ethernet are mounted on the system module. The network components on the VAXstation 2000 / MicroVAX 2000 system module are inactive until the DESVA option module is installed. [1]
