2.4 Handshake Format Selection
In order to ensure proper data transfers between the recorder and the host computer via the RS-232-
C interface, a mutual procedure is required for processing the electrical signals. Such a procedure is
referred to as a ‘handshake’. Several handshake formats are available, with selection depending on
the host computer being used. The same handshake format must be designated for both the recorder
and the host computer.
The recorder parameter settings permit any one of the following 5 formats to be selected.
Transmission Data Control
(Control format when transmitting data
to the host computer)
Reception Data Control
(control format when receiving data
from the host computer)

When reception
of data becomes
impossible RTS
becomes
FALSE, when
data recept
becomes
possible RTS
becomes TRUE.
When reception
of data becomes
impossible DTR
becomes
FALSE, when
data recept
becomes
possible DTR
becomes TRUE.
Transmission
is stopped
when CTS is
FALSE, and is
resumed when
CTS is TRUE.
Transmission is
stopped when
X-OFF is
received, and is
resumed when
X-ON is
received.
OFF-OFF
• Transmission data control : There is no handshake status between the recorder and host
computer. the X-OFF signal from the host computer is processed
as data, and the CTS signal is ignored.
• Reception data control : There is no handshake status between the recorder and host
computer. When the recorder reception buffer becomes full, the
excess data is discarded.
DTR=True, RTS=True (both fixed).
Note
• It is necessary to create a host computer program which prevents the recorder and host computer reception buffers from
becoming full.
XON-RTS
• Transmission data control : A software handshake status is established between the recorder
and the host computer. The recoeder will stop a data transmission
when an X-OFF signal is received from the host computer. The
transmission will be resumed when the next X-ON signal is
received.
The CTS signal from the host computer is ignored.
• Reception data control : A hardware handshake status is established between the recorder
and the host computer. When DA100 recept of data becomes
impossible, an ‘RTS=False’ status will be established. When data
recept becomes possible, an ‘RTS=True’ status will be established.
DTR=True (Fixed).
