Commands
Host-transmitted commands can be used to control the operation of the reader.
These commands may be transmitted by host software or manually entered using a
terminal emulator.
Note: Tag identification (ID) codes are not transmitted by the reader when in
command mode. If the reader is left in the command mode too long, the tag
buffer will fill up and any additional tag IDs will be lost. SmartPass must be
returned to data mode as soon as possible to ensure proper transmission of
acquired tag IDs.
Sending manual commands to the reader is a three-step process:
Note: Basic protocol (not error correcting protocol) should be used when
manually entering commands.
1. Put SmartPass into command mode by typing #01 and pressing the enter or
return key. # is the start of message character, and 01 is the command number
to switch to command mode.
2. Type # and the appropriate command number, and press the enter or return key
(no spaces).
3. Return SmartPass to the data mode by typing #00 and pressing the enter or
return key.
Command Listings
Table 9-1 lists factory default settings. Table 9-2 lists all of the commands
available to users with the commands in order by command number. Table 9-
3 lists the same commands in order by command name.
Command numbers consist of 2 to 4 hex digits. The letters
N
or
S
may follow
a command number. The letter
N
indicates that part of the command number
is variable. The letter
S
indicates the requirement for an alphanumeric data
string that is to be included immediately following the command number.
Hex digits (0–9, A–F) must be used for all command number entries. Either
uppercase or lowercase characters may be used in data strings and for hex
digits A–F.
