Imager Status Requests
Imager Status Requests
<?> Status Byte
The imager responds to a status request
<?>
with a two character hex value, such as
<?/22>
.
To determine 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
.
2. Next, enter your binary values from the table below in the
“Binary” column next to the appropriate bit.
3. Under “Binary,” interpret
1
s as true and
0
s 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
“Imager is in a read cycle”.
<K?> All Status Request
This is the fastest way to learn the imager’s current configuration. Sending this request will
return the current settings of all commands, starting with the lowest K command value and
ending with the highest K command value.
<K??> All Descriptor Status Request
This request will return all current descriptors for every K command, starting with the lowest
K command value and ending with the highest K command value.
<K?#> All Range Status Request
This request will return the current settings of all commands within the user-defined range,
starting with the lowest user-defined K command value and ending with the highest
user-defined K command value.
Bit Binary Imager Status

1 1 Command received
2 0 Communication error detected
3 0 Flash sector unprotect failure
4 0 Host/Aux port buffer overflow
