| be assigned. The default is 0, and other |
| acceptable values range from 1 to 9999. |
startblock | Location where data will be read from the |
| RFID tag. The PPI1 only supports Alien |
| Technology Class 1a tag, which has only |
| one |
| will be set to 0, regardless of the |
| specified value. |
length | The number of blocks to be read from the |
| RFID tag. The PPI1 only supports Alien |
| Technology Class 1a tags, which have |
| only one |
| will be set to 1, regardless of the |
| specified value. |
hexformat | This flag indicates whether the data, after |
| being read from the RFID tag, should be |
| translated into hexadecimal format. The |
| default is 0, meaning the data will not be |
| translated. The other acceptable value is |
| 1, meaning the data will be translated |
| into hexadecimal format. |
retriescount | The number of automatic attempts to |
| read data from the tag if previous reads |
| failed. The PPI1 absorbs the number and |
