EMBEDDED SD CARD

The 2166 Rugged Bluetooth® UHF RFID Reader is factory ﬁtted with an embedded 2GB internal NAND storage SD

card, allowing millions of tags to be stored with time and date stamping.

By default the SD card is presented as a mass storage device when the 2166 is docked into a cradle connected

over USB to a host computer. This allows rapid download of log data and editing of the Auto Run File. The standard

ASCII 2 SD card commands can still be used, but only when the SD card is not in mass storage mode.

SUMMARY

Once an SD card is installed and logging is enabled a log ﬁle is created on the SD card. The ﬁle is located at the

root of the card and called “LOG.TXT”. All the lines from every response to every command that is executed by the

reader (including those performed from trigger actions) are appended to the end of the ﬁle. Events such as Power

up are also appended to the ﬁle.

The ASCII 2 Read Log File command (‘.rl’) is provided to enable or disable logging, to read the log ﬁle from the

card or to delete the log ﬁle from the card.

Please note that the log ﬁle can quickly become large relative to the speed at which it can be downloaded using

the Read Log File Command.

Once an SD card is installed an Auto Run ﬁle can be created on the SD card. The Auto Run ﬁle contains a list of

ASCII 2 commands that are executed as the 2166 powers up. The ﬁle should be located at the root of the card

and called “AUTO.TXT”. Although the ﬁle can contain any valid ASCII 2 commands, one per line, it is intended that

these have the take no action ‘-n’ ﬂag speciﬁed to allow the default parameters for any command to be changed

from the ﬁrmware defaults as the unit boots without actually executing the command.

For example to change the carrier power of the inventory command from 29dBm to 20dBm

‘.iv -o20 -n’ would be appended to the Auto Run ﬁle. As is the behaviour with command parameters this will set

the output power for the inventory command until a new value is sent with this command. Therefore the inventories

executed by the trigger, which executes ‘.iv’ will use the modiﬁed output power.

The Auto Run ﬁle can be manually created on the card before it is inserted into the 2166 or the ASCII 2 command

Write Command to Auto Run File ‘.wa’ can be used. The Read Auto Run File ‘.ra’ can be used to read back the

contents of the Auto Run ﬁle or delete the ﬁle from the card.
