Idle Time:
Idle time to "Force transmit" defines how long the unit should wait before sending
accumulated characters. This wait period is between characters. If there is an idle period between
characters equal to the force transmit set, then the unit will package up the serial data currently in
the buffer and send it to the network.
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 not set, they are interpreted 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 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 connection is dropped if there is no activity on
the serial line before the set time expires. Enter time in the following format:
mm:ss
, where
m
is
the number of minutes and
s
is the number of seconds. To disable the inactivity timeout, enter
00:00
.
DisConnTime (00:00) ? _
To disable the inactivity timeout, enter
00:00
. Range is 0 (disabled) to 5999 seconds (99 minutes,
59 seconds). Default setting is
0
.
