Refer to Figure b on the preceding page.
*COM2 does not support this function.
This setting defines the serial output data framing.
In Transparent mode (default), the received data will be output
promptly from the IP Series.
When set to Seamless, the serial port server will add a gap
between data frames to comply with the MODBUS protocol for
example. See ‗Character Timeout' on the next page for related
information.
In Seamless mode (see Data Mode described on the preceding
page), this setting determines when the serial server will consider
the recently-received incoming data as being ready to transmit. As
per the MODBUS standard, frames will be marked as ‗bad' if the
time gap between frames is greater than 1.5 characters, but less
than the Character Timeout value.
The serial server also uses this parameter to determine the time
gap inserted between frames. It is measured in ‗characters' and
related to baud rate.
