Alternate Packing Algorithm (Pack Control)
Enable 1
Pack Control
Two firmware-selectable 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.
