For example, to setup a color pattern where the LED illuminates green-red-green-red, the byte value
would be “01100110” (decimal 102). The decimal value of this byte is used with the LE command. In this
example, the LE command is executed as follows:
LE 102
Table 3-1 lists common color patterns with their values and descriptions:

Once the color pattern is defined, the pattern is repeated for a default interval of 3 seconds. A different
time period can be specified using the LE command and providing a new value in seconds, up to 65. For
example, to setup a 5 second interval for the color pattern above, the LE command is executed as follows:
LE 85,5
Note
The total time for each color pattern is 0.4 seconds (i.e. each segment lasts 0.1 seconds).
DM – DISABLE MICRIMAGE COMMAND
This command disables the document reading function and turns off the LED. Communications are not
affected, and Insta-change checks may still be scanned, but the MICR line will not be sent.
DM Insta-change checks only may be scanned
DMX No scans at all
