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. The default setting is 00 (none).

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. The default setting is 0 (disabled).

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). The default setting is 0.

Note:

A transmission might occur if status information needs to be

exchanged or an acknowledgment needs to be sent.
