1. 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 not set they are interpreted independently If Send Immediately After Send Characters is not set any characters already in the serial buffer are included in the transmission after a transmit condition is found If 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 3 13 14 DisConnTime Inactivity Timeout Use this parameter to set an inactivity timeout The connection is dropped if there is no activity on the serial line before the set time expires Enter time in the following format mm ss where m is the number of minutes and s is the number of seconds To disable the inactivity timeout enter 00 00 Range is 0 disabled to 5999 seconds 99 minutes 59 seconds Default setting is 0 3 30 NET232 NETUSB User Guid
