Reader Status Requests

<?> Scanner Status Byte
The scanner responds to a status request
example <?/22>. To determine the status:
1. Look up the binary conversion in
For example, the first
through 0; the second
2. Next, enter your binary values in
appropriate bit.

3. Under "Binary," interpret 1s as true and the 0s as not
true. For example, bit 1 has a
umn, indicating "Command Received." Bit 5 is also a
1 indicating that the "Scanner is in a read cycle."
<?1 > Extended Status
The scanner responds to an extended status request
<?1> with several fields, for example: <?/F><?1/35-
338200-12,35-338201-14,476C,33,33>.
These represent: the status byte discussed above, the boot part number (35-338200-
12), the application part number (35-338201-14), the fpga part number (5-559001-
18), flash checksum (476C), current RAM parameter checksum (33), and flash param-
eter checksum (33).
<K?> Configuration Command Status
Returns the current status of all configuration commands.
