Packing Interval: Packing Interval defines how long the unit should wait before sending
accumulated characters. This wait period is between successive network segments
containing data. For alternate packing, the default interval is 12 ms.
Trailing Characters: In some applications, CRC, Checksum, or other trailing characters
follow the end-of-sequence character; this option helps to adapt frame transmission to
the frame boundary.
Send Characters:
. If 2-Byte Send Character Sequence is enabled, the unit interprets the sendchars as a
2-byte sequence; if this option is not enabled, the unit interprets them independently.
. If Send Immediately After Characters is not set, any characters already in the serial
buffer are included in the transmission after a "transmit" condition is found. If this
option is set, the unit sends immediately after recognizing the transmit condition
(sendchar or timeout).
Note: A transmission might occur if status information needs to be
exchanged or an acknowledgment needs to be sent.
DisConnTime (Inactivity Timeout)
Use this parameter to set an inactivity timeout. The unit drops the connection if there is no
activity on the serial line before the set time expires. Enter time in the format mm:ss, where m is
the number of minutes and s is the number of seconds.
DisConnTime (0: 0) ?:
To disable the inactivity timeout, enter 00:00. Range is 0 (disabled) to 5999 seconds
(99 minutes, 59 seconds). The default is 0.
SendChar 1 and SendChar2
Enter up to two characters in hexadecimal representation
SendChar 1 ( 0) ?
SendChar 2 ( 0) ?
If the unit receives a character on the serial line that matches one of these characters, it
sends the character immediately, along with any awaiting characters, to the TCP connection.
This action minimizes the response time for specific protocol characters on the serial line
(for example, ETX, EOT). Setting the first SendChar to 00 disables the recognition of the
characters. Alternatively, the unit can interpret two characters as a sequence.
