User Guide, WherePort IV D1300 REV A
© Copyright WhereNet, Corp. 2008 WhereNet Confidential
The password can be set using the ****:XPW **** command. Changes to the password will take effect
immediately. The changes affect only the current session unless the host sends the WherePort IV an
execute command (****:EXE). Only after receiving an execute command will the new password be
written into flash memory and read on power up. Without the execute command, the password will return
to its previous value if the WherePort IV is powered down.
12.3. Command Execution
The following commands require the execute command (****:EXE) before they will be saved in flash
memory and sent to the magnetic field generator:
MSG, PWR, PHS, WID, TID, RSP, CNT, INT, TRG, DAT, CMW, CMC, XPW
A query command will return the newly entered values, even though the execute command has not been
sent. The WherePort IV will not be operating under these values until the execute command is sent.
12.4. Tag Responses to Commands
Unless noted otherwise, all commands will produce one of the following responses by the WhereTag:
ACK message OK
NAK message not recognized or bad format
NAK2 message parameter out of range
There are two other possible acknowledgments that are used primarily by data commands. Their use will
be noted in the command summary.
NAK3 The tag is busy and will not blink data
BSY…ACK The tag is busy with a WherePort IV blink. The command will be responded to when the
tag completes the WherePort IV blink and is not busy, at which time a ACK response will be sent.
SSS n Response to a query where SSS is the command and n is the parameter.
All tag response strings consist of a carriage return / line feed, the actual response string, another
carriage return / line feed, and are followed by the > prompt character.
{CR}{LF} ACK{CR}{LF}>
