In most of the variants of these cables, on the top of that plastic block is also an RJ-22 connector (telephone handset connector) for an LK-series keyboard, and a MicroDIN connector for a DEC-protocol mouse.
ok I did think that this might be the case, but the manual does not mention a keyboard so I became unsure if this was a terminal or display, or something special purpose.
Well the keyboard and mouse just plug onto the cable, not to the monitor...the monitor is just a regular dumb analog video monitor, nothing more. The DA15 connector on the other end of the cable also (obviously) carries the keyboard/mouse signals, but they are separate from the video. That cable can be very long, I've seen them at 75 feet, so that the "workstation" kbd/mouse/CRT end can be in an office while the machine it's connected to can be in a datacenter down the hall or whatever, with just one cable. (aside from power for the monitor of course) But there are different cables, depending on what type of system you're planning to connect it to, just beware of that. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
