Using Setup Mode for Configuration is used in a local environment, allowing for very small delays for single characters, while keeping the packet count low. The alternate packing algorithm minimizes the packet count on the network and is especially useful in applications in a routed Wide Area Network (WAN). Adjusting parameters in this mode can economize the network data stream. Pack control settings are enabled in Flush Mode. Set this value to 00 if you do not need specific functions. Table 4-12.

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 12ms.
Trailing Character
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. To
disable the inactivity timeout, enter
00:00
. Range is 0 (disabled) to 5999 seconds (99
minutes, 59 seconds). The default is 0.
