16-3-3. Operating mode of RS-232C and RS-422/485
The operation mode of RS-232C is selected by the setting of function F-40.
The operation mode of RS-232C is selectable from [Command mode], [Stream mode] and
[Synchronized with print].
Default is selected as [Command mode].
The operation mode of RS-422/485 is selected by the setting of the function F-49.
The operation mode of RS-422/485 is selectable from [Command mode], and [Stream mode].
Default is selected as [Command mode].
When you select the stream mode, the data keeps being output at constant intervals. Also, control
from the host becomes impossible.
