In a daisy chain configuration, where multiple domes are
connected in series, the 100 Ω resistor must be removed from
all but the last dome. You can daisy chain a maximum of four (4)
AutoDomes.

3.4.2 Controlling the AutoDome via the RS232 Protocol
(3-wire, full-duplex, single-ended, 50 ft. cable limit)
RS232 is a common, single-ended communication protocol
used for control. Data transmission via 3-wires (TDX, RXD,
common) is from one transmitter to one receiver at relatively
slow baud rates (up to 57.6 Kbaud) and short distances up to
50 ft.
