Chapter 9: Setup Mode: Channel Configuration

Flush Mode (Buffer Flushing)

Using this parameter, you can control line handling and network buffers with connection startup and disconnect.

FlushMode ( 0) ? _

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 that particular option, which can be set to either a 0 or 1 value.

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.
