I just received my shipment today after some back/forth go-rounds. I have ordered a 24-zone system.
By my calculation I should have 4 boards. (4 x 6 = 24). However the shipment contains 8 boards.
Also the boxes labeled 6-zone interface have a ribbon cable and module with no power connector while the boxes labeled 6-zone expansion have a board that has a power connector on it. (seems backwards)
Am I not understanding something basic here or is something terribly wrong?
