Commands sent to the controller via the serial, USB, or parallel interface are structured in a
one-byte (8-bit) signal. Some commands are followed by one or more bytes containing
additional parameter information for the command. The 8 bits can be used to convey three
types of commands.
Filter Commands. Filter Commands. Filter Commands. Filter Commands. These commands select the desired filter position and switching speed.
The filter position and switching speed are each specified by the encoding of specific bits
within the command byte.
1.
The filter position is specified in the least significant 4 bits (nibble) of the byte (Bits 3,
2, 1, and 0), providing value range of 0 through 9. Because only 10 possible filter
positions are encoded in these bits, they are effectively encoded in Binary Coded
Decimal (BCD) format, leaving the values of 10 through 15 (decimal) available for use
by Shutter and Special commands.
2. The filter switching speed is specified in the least significant 3 bits within the most
significant nibble of the byte (Bits 6, 5, & 4), providing a value range of 0 through 7.
These bits are interpreted as the filter switching speed only if the bits in the lower
nibble of the byte contain a value of 0 through 9, specifying the filter position as
described previously
3. The filter wheel selection is specified in the most significant bit of the byte (Bit 7).
This bit is set to 0 to indicate the first (Wheel A) or the third (Wheel C), and is set to 1
to indicate the second wheel (Wheel B). When the third wheel (Wheel C) is indicated,
a prefix byte is required before the filter wheel command byte, in order to indicate
that the filter wheel command byte refers to Wheel C and not Wheel A.
Shutter Commands. Shutter Commands. Shutter Commands. Shutter Commands. These commands control the open and closed states of shutters as
well various modes in which SmartShutters can operate.
Special Commands. Special Commands. Special Commands. Special Commands. These commands are used to control various aspects of the controller
that are not specifically related to either filters or shutters. Some of these commands are
also used to obtain status and configuration information of the controller.
