7: Setup Mode: Channel Configuration

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.

Packing Interval

Packing Interval defines how long the unit should wait before sending accumulated characters. This wait period is between successive network segments containing data. For alternate packing, the default interval is 12 ms.

Trailing Characters

In some applications, CRC, Checksum, or other trailing characters follow the end-of- sequence character; this option helps to adapt frame transmission to the frame boundary.

Send Characters

If 2-Byte Send Character Sequence is enabled, the unit interprets the sendchars as a 2-byte sequence; if this option is not enabled, the unit interprets them independently.

If Send Immediately After Characters is not set, any characters already in the serial buffer are included in the transmission after a "transmit" condition is found. If this option is set, the unit sends immediately after recognizing the transmit condition (sendchar or timeout).

Note: A transmission might occur if status information needs to be exchanged or an acknowledgment needs to be sent.
