8: Setup Mode: Channel Configuration
Flush Mode (Buffer Flushing)Using this parameter, you can control line handling and network buffer s with connection
startup and disconnect.
FlushMode (00) ? _
You can also select between two different packing algorithms.
Note: All bit positions in the table that are blank represent “don’t care” bits, for t hat particular
option, which can be set to either a 0 or 1 value.

Alternate Packing Algorithm (Pack Control)
Enable
1
The packing algorithms define how and when packets are sent to the net work. The standard
algorithm is optimized for applications in which the unit is used in a l ocal environment,
allowing for very small delays for single characters, while keeping the pac ket 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 param eters 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.
