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.
