ViewStation Power Connectors
The ViewStation has an auto-switching power supply, so it can accept either 115 VAC or 230 VAC input without requiring any adjustment.

The ViewStation's convenience outlet is an unswitched outlet and provides the same power as output that the ViewStation receives as input. The convenience outlet is rated for a 2.5 Amp 120 VAC power load, which is higher than any of the standard ViewStation monitors require. If you substitute another monitor, or use the outlet for another device, be sure you stay within the 2.5 Amp power rating.

The fuse on the back panel of the ViewStation base unit is rated at 4 Amps for 115 Volt operation (this is a Littlefuse 239004). For 230 Volt operation, the fuse should be changed to a 2 Amp fuse (Littlefuse 239002). A spare fuse is included in the fuse holder.

ViewStation Communications Board
The optional communications board supports a ThinWire Ethernet connection with a BNC female connector conforming to IEEE 802.3 10Base2 standards, a ThickWire Ethernet connection (DB15) conforming to IEEE 802.3 10Base5 standards, and a second serial port (DB25 connector).

ThickWire Ethernet
This page gives the pin assignments for the ThickWire DB15 connector.

Serial Port 2 - DB25 Connector
This page gives the pin assignments of the ViewStation's Serial Port 2.

Sun Keyboard Connector
This page gives the pin assignments for the optional Sun keyboard connector.

Other connectors, such as the PCMCIA interface, Audio, and Video connectors, are described in the pages describing their operations.
