• Connect "RS" of the DX100 to "CS" of a host computer.
This prevents data overrun when reception processing speed of the
DX100 cannot catch up with data sending from the host computer.
In other words, "RS" signal from the DX100 controls start-hold of
data transmission from the host computer.
The sending interface controller must be capable of coping with CS
input displacement in units of a single byte.
• The DX100 sends data when the "CS" signal is ON.
