Falcon 4-Slot Dock
The back panel of the Falcon 4-Slot Dock has a 25-pin dock-to-host cable
connector and two telephone-style cable jacks: one for “upstream”
communications and one for “downstream” communications. The upstream
side is the side closer to the host; the downstream side is farther from the host.
