7-9
Packet length
Default 0
Options 0 to 1024
Description This field specifies the maximum amount of data that is allowed to accumulate in the serial
port buffer before sending.
0: Packet length is disregarded and data in the buffer will be sent as specified by the delimiter
settings or when the buffer is full.
1 to 1024: Data in the buffer will be sent as soon it reaches the specified length.
Delimiter 1 and 2
Default Disabled
Options Disabled, Enabled, 00 to FF
Description These fields are used to define special delimiter character(s) for data packing. Enable
Delimiter 1 to control data packing with a single character; enable both Delimiter 1 and 2 to
control data packing with two characters received in sequence.
When these fields are enabled, serial data will accumulate in the serial port’s buffer unti
l the
buffer is full or until the specified delimiter character(s) are received. For example, the
carriage return character could be used as a delimiter in order to transmit each sentence or
paragraph in a separate packet. Data will be packed according to Delimiter process.
Delimiters must be incorporated into the data stream at the software or device level.
Delimiter process
Default Do Nothing
Options
Do Nothing, Delimiter + 1, Delimiter + 2, Strip Delimiter
Description This field specifies how data is packed when delimiter characters are received. This field has
no effect if Delimiter 1 is not enabled.
Do nothing: Data accumulated in the serial port’s buffer will be packed, including delimiters.
Delimiter + 1: One additional character must be rece
ived before the data in the serial port’s
buffer is packed.
Delimiter + 2: Two additional characters must be received before the data in the serial port’s
buffer is packed.
Strip Delimiter: Data accumulated in the serial port’s buffer will be packed, but the delimiter
character(s) will be stripped from the data.
