An optional Micro SD card can be installed in to the 2128P reader. The card should be SD/SDHC compatible,

FAT16 or FAT32, with a maximum capacity of 32 GB.

The card is inserted into the marked slot in the battery compartment. The Micro SD card slot is spring loaded. After

inserting the card into the slot, push and release the card once to lock the card into the holder. Once locked in a

further push and release a will eject the card and it can then be removed from the slot.

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 2128P 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 2128P 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.
