Alternate Packing Algorithm (Pack Control)

Pack Control
The packing algorithms define 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, 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.
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.
