Reader Status Requests

The reader responds to a status request <?> with a two character hex value, such as <?/22>. To deter-
mine status:
1
Look up the binary conversion in the table below.
For example, the first hex 2 would be 0 0 1 0 in binary, as read from binary digits 3 through 0;
the second hex 2 is also 0 0 1 0 as read from binary digits 7 through 4.

Next, enter your binary values from the table below in the "Binary" column next to the

Under "Binary," interpret 1s as true and 0s as not true. For example, bit 1 has a 1 in the "Binary"
column, indicating "Command Received". Bit 5 is also a 1, indicating that the "Reader is in a
read cycle".
