A further test in command mode with Legacy. I was only able to get the ZW-C to receive commands from the command base by running a wire from the base to the common posts on the ZW. In command mode, B and C (TR 2 and 3) behave as expected. Channel A / TR 1 likewise behaves as expected (voltage is initially low then dials up to ~12.5V, same maximum as in conventional). Channel D (TR 4) remains fixed at ~18V regardless of the position of the handle or whatever commands are sent via the remote.
