Using Configuration Symbols
Once in symbol configuration mode, serial command data encoded in Code 128 symbols
is read by the reader as serial input.
Configuration symbols must meet the following conditions:
1. The only valid configuration symbols are Code 128.
2. Symbol data may contain more than one command, but individual symbols must
be presented one at a time. This is because only the first symbol in a read cycle
record will be used as a possible configuration symbol.A symbol that is presented
to the reader must be read 25 times consecutively to be used as a valid symbol.
Once this is done the reader will interpret the symbol data in the same fashion as
it interprets serial data.
3. Any valid command may be entered via symbols including operational commands.
Because the data is treated like serial input multiple symbols may be used to rep-
resent one command as long as the symbols are presented individually and in the
correct order.
4. Read rate command may also be used to enter read rate from symbol configura-
tion mode.
5. When in read rate, the reader will read the symbologies that were enabled prior to
entering the configuration mode. However it will read a "<J>" in code 128 regard-
less of current enable/disable state of code 128.
Once the <J> is issued the reader exit both read rate and symbol configuration.
To exit read rate and remain in symbol configuration, you present the start symbol
once again. Symbols read in read rate will not configure the reader.
To start a read rate test, scan this symbol:
Exiting Symbol Configuration
There are multiple ways of exiting symbol configuration. The first way is to simply read
or serially enter the "<J>" command. Other ways include any command that executes
a software reset. These commands include the save family as well as the reset family
e.g. <Z>, <Zc>, <Zrd>, <Zrc>, <A>,
configuration with the symbol "<J>," the reader will beep in response.
To end the read rate test and the symbol configuration program, scan this symbol:
This will terminate symbol configuration mode. Changes made in configuration will
remain in effect just as would changes made in the menus or by serial commands.
