The Séance box communicates with the PCs over a 10Base-2 Ethernet connection
via a 50 ohm BNC cable terminated at each end with a 50 ohm terminator. The
Séance box has two BNC connectors for each PC interface, which are wired in paral-
lel inside. A 50 ohm terminator plugs into the BNC socket labelled TERMINATOR
and the Ethernet cable plugs into the BNC socket labelled COMPUTER. A termina-
tor and T-piece are used to connect the Ethernet cable to the PC.
