BRICK SEQUENCER
For best results, please observe these points:
● only use black or gray bricks to ensure
correct detection (add another one on
top with the color you like).
● use the module in a closed modular rack
(light from inside the rack can disturb
sensors).
● do the calibration procedure at the place
(with proper light environment) you will
use the module.
CALIBRATION
● set the light environment in the condition you’ll use the module.
● place the 1x16 bar on the row you will calibrate.
● press and hold RECALL then press SAVE. (RECALL, SAVE, and encoder
leds will flash).
● with the rotary encoder, select the row you want to calibrate (according led will
flash).
● push the rotary encoder to validate, the sequence leds will flash back and
forth and the row is now calibrated.
● repeat operation for the 5 rows (don’t forget the 5th row for in and out points).
● Now the module is calibrated and reference data is stored, you’ll have to do
this operation again only if you encounter problems or if the light environment
changes dramatically.
● to exit calibration mode without changing anything, press again RECALL and
SAVE.

CONFIGURATION MODE
There are some preferences you can set with configuration mode. To enter
configuration mode: press and hold RESET, press and hold MUTE 1, press MUTE 4
(release the 3 buttons).
Then, select the led you want to toggle and push the encoder. To exit the
configuration mode, press SAVE.
● RESET BEHAVIOUR
> LED OFF: when a reset pulse on the reset input or a press on the RESET
button occurs, the sequence will return to the first step when the next clock
pulse appears at the clock input.
> LED ON: sequence will jump immediately to the first step (old style).
● SENSITIVITY
> one led on: this is minimum sensitivity to light: unit needs more time to
detect bricks but this ensures minimal error caused by shades (operator
hands / other bricks).
> four leds on: maximum sensitivity to light: this gives a faster response but
unit is more sensible to shades too.
this is the default configuration:
