Loadleak / channel lab

System load sender

Send bits or ASCII text at a fixed logical bit rate: a wire 1 runs the selected load method and a wire 0 lets the workers sleep. Watch the receiver’s graph for the pattern. No pairing is needed for manual transmission.

Constant load

Uses the load method selected below. Useful for checking that the receiver can distinguish the two channel states.

Live progress & bit display

Progress updates once per second without animation. Switch off to pause progress and per-bit updates while transmitting. The load schedule and Stop button keep working.

Pair with a receiver

The receiver can prepare and schedule finite tests after you connect. It cannot send code or start a permanent load.

Disconnected

Pair code

Use the same pair code shown by the receiver.
