Description of superimpose picture
1 The communication baud rate is displayed on the
superimpose picture. The baud rate can be selected
from among the followings. (The factory setting is
19.2 K.)

count, but as "xx".
5 The TXD/RXD signal displays the number of data
items (number of bytes) properly sent and received in
this unit in four digits (hexadecimal).
Other signals display the connection state of an RS-
232C connector in a high level (+3 V or more, or non-
connection) and low level (_3 V or less).
If no object for communication is connected to the RS-
232C connector, TXD and RXD are displayed as
"xxxx".
Setting of communication baud rate
(1) Turn the search dial while pressing the JOG button and
display the desired baud rate.
. Message "Push SET Button" is displayed on only
the superimpose picture when the setting is changed.
. To cancel the setting, press the MENU button to
terminate this menu.
(2) Press the SET button to save the setting.
. Message "Saving ..." is displayed on only the
superimpose picture. If no abnormality is found, the
display changes to "Save Complete" after a few
seconds.
To turn off "Save Complete", turn the search dial.
n
A white square is displayed in the upper-right position of
the superimpose picture when the SET button is pressed
except during communication baud rate setting. This unit
then enters the ordinary operation state (in which the
ordinary operation of this unit except a menu system can
be performed).
However, the character information (time code or opera-
tion status) superimposed during ordinary operation is not
displayed.
To return to the former state, press the MENU button.
