The following are detailed explanations of the fields on setup screen #1. We
have provided reference letters (a through gg) which are keyed to Table 4.C
and Figure 4.2.
Note: Fields with reference letters (a) through (t) control the format of bar
code data that is sent to a host device. Refer to Figure 6.5 for an illustration
of the data format. Table 6.A provides a short explanation of each field in a
data message.
Message Format
SEND BAR CODE DATA (a) - Selecting YES for this field will enable the
decoder to transmit the bar code data message to the host (refer to Figure
6.5). The bar code data message will not be sent to a host if you select NO.
SEND PACKAGE COUNT (b) - Selecting YES for this field will enable
the decoder to transmit the contents of the package counter to the host.
Package counts will not be sent if NO is selected. Refer to Figure 6.5, item
#14.
SEND BAR CODE TYPE (c) - Selecting YES for this field will enable the
decoder to transmit the type of code being decoded (Codabar, Code 39, etc)
to the host. Bar code type will not be sent if NO is selected. Bar code type is
transmitted as a 2 digit code, refer to Table 6.A. Figure 6.5, item #5
illustrates the position of the data in the data message.

decoder to transmit the contents of the SOURCE IDENT field to the host.
Source identification will not be sent if NO is selected. Refer to Figure 6.5,

the decoder to transmit the contents of the NO-READ MESSAGE field to the
host whenever a no-read occurs. The no-read message will not be sent if NO
is selected. Refer to Figure 6.5, item #8.
EXPAND UPC-E (g) - Selecting YES for this field will result in UPC-E
being transmitted in a 12 digit (expanded) format. UPC-E will be
transmitted in a 6 digit (compressed) format if NO is selected.
SOURCE IDENT (h) - You can enter one of two options:
1) The identification label you want sent to a host with each communication
(Send Source Ident selected). This entry is limited to 4 ASCII characters.
