Start Character - This field specifies a unique starting character value (in
decimal) that can be used to trigger the receipt of information. The charac-
ter cannot appear at any other time in the download. If a unique start char-
acter is not available, set this field to zero.
Terminators - These three fields can be used to specify up to three charac-
ters that will terminate the download. If only one terminator is needed, set
the second and third to zero. For example, if the download is terminated by
carriage return (CR) and line feed (LF), set the first field to 13 (decimal
equivalent of CR), the second field to 10 (decimal equivalent of LF) and the
third field to zero.
Character to Ignore - This field can be used to specify a character (in deci-
mal) that is to be ignored wherever it may appear in the download.
Echo Received Characters - This checkbox is used to enable the echo of all
received characters back to the host computer.
Reply with Ack or Nak - This checkbox is used to enable a reply back to the
host with either an ACK character if the message was received without er-
ror, or with a NAK character if the message overflowed the receiver’s
buffer.
Use Fixed Field Positions - This checkbox is used to enable the parsing of
the data fields using fixed field locations. If checked, you must supply the
character offset and field lengths for up to 10 text fields. The data will be
extracted using these rules. If this field is not checked, then the data will be
expected in a variable length, delimited format called the "Standard Mes-
sage Format". The delimiter must be the Data Field Separator as specified in
the Connection Type tab.
Fixed Field Positions - This table is used to specify the fixed fields to be
used to extract the data. This table is only used if the Use Fixed Field Posi-
tions checkbox is checked. You must specify the field’s starting character
offset (the first character received is 1) and the number of characters occu-
pied by the field.
