5–24 Configuring Your Reader
Publication 2755-6.9
Most of the configuration changes to the reader that can be made in
the menu can also be accomplished by command strings from the
host.
Serial command strings are entered from an ASCII device. As with
menu configuration commands, serial configuration commands relate
to the initial reader setup.
Serial Configuration Command Format
The format for a serial configuration command is:
<Kparameterdata,data,...etc.><initializing command>
Keep the following in mind when using serial configuration
commands.
•
Less than < and greater than > symbols are included as part of the
commands.
•
“parameter,” as used here, are those character(s) that precede the
data.
•
The “initializing command” <A> or <Z> is sent after
configuration is complete. <Z> resets and saves for power up.
<A> initializes the change to RAM.
•
Parameters and data are “case sensitive.” That is, characters must
be entered as upper or lower case, as specified.
•
All data fields (except the last) must be followed by a comma
(without a space).
•
If there is no change in a given field, then commas can be entered
alone, or with the existing data (for example, <Ka,,,0> or
<Ka4,1,0,0>).
•
All fields preceding the modified field must be included. For
example, in Host Port, to change Data Bits to Eight without
changing any other field, press either:
[<Ka,,,1>] or
[<Ka4,1,0,1>] .
•
All fields following the modified field can be left out. For
example, in the RS-232 port, to change Baud Rate to 4800, press
[<Ka3>] .
To ensure that a serial configuration command will take affect,
follow it with one of the operational commands below.
•
<A> To reset but not save changes for power-on
•
<Z> To reset and save changes for power-on
For example, to change Baud Rate and reset without saving changes
for power-up, press
[<Ka3><A>] .
To change Baud Rate and reset, saving the changes to NOVRAM,
press
[<Ka3><Z>] .
