Pack Control
The packing algorithm defines how and when packets are sent to the network. The
standard algorithm is optimized for applications in which the unit is used in a local
environment. 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 specific
functions are not needed.
Note:
All bit positions in the table that are blank represent “don’t care” bits for
that particular option, which can be set to either a 0 or 1 value.

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).
