Daisy Chaining
Daisy chaining allows many panels to connect to the
computer along a single serial line.
The first panel is connected directly to the computer and a
second panel connects to the first panel. Additional panels
connect in the same way, one after another.

At each end of the data line, both where the panel connects
to the computer and on the last panel in the network, a
termination resistor of 120Ω may be required. Apply the resistor
across the L1 and L2 connections.
These termination resistors are especially important in long
cable runs.
