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). Default setting is 0.
