RFTools Destination Analyzer
This is a passive block that you can place next to a dialing device. It enables the dialing device to check the status of a receiver. This way you can be sure that a receiver has enough power or is not blocked before attempting to make a connection.
You can also place a destination analyzer next to a transmitter. In that case the transmitter will show a red colored teleportation beam if there is something wrong on the receiving end. You can check the actual problem in the dialing device.
The destination analyzer also knows how to check for power in the destination dimension in case the destination is an RFTools dimension. If the power is too low the beam will also glow red.
