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

would be

0 0 1 0

in binary, as read from binary digits 3

through 0; the second hex

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 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

“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.
