Wire managment hub

[jyang72211]

This is a wiring questions.  I have four wires that need to go to device 1, 2, and 3, i.e. all devices need equal access to the four wires.  I would like to build a hub that allow the 4 wires to go on one end and on the other end there would be 3 ports for device 1-3.  Any hub like device out there that I can use?

What would the hub be used with?  USB? Ethernet? others?

It would fall under others.  I am trying to improve my setup when we connect 3 power meter to a 4 wires com, to power (3 wires), etc.  Right now, the wires are connected to device 1 and daisy chain to the rest of them, but I want to get a hub that I can modify, so that I can use the star topology instead of daisy chaining.  The hub must be a really simple 1 to multiple devices without any logic instead.  Thanks!

GPIB?

can you provide more details as to what the "wires" are or represent?  Is this part of an AC power / phase measurement?

We need more details, as it can be interpreted to be anything...

It is not GPIB.

Well, glad that's settled. Only 5 billion other possibilities to go. Anyone want to guess first?

You've got options here - red, yellow, blue, grey...

Sorry all.  Let me clarify a little.  I have a 3 wires from a RS-485, and I have 3 wires from power (hot, ground, shield).  I have multiple devices that need all these wires.  At the moment, I am daisy chaining them, but I am wondering is there a hub out there that would allow me to change the daisy chain into a star topology.

Terminal blocks that you can jumper together?
