Setting the brightness to 0% results in LED to be off. Setting the brightness to 50% results the in the LED being driven with PWM with 50% duty cycle.

This documentation for v2.88+, though the Y parameter was added ~v2.86. ​ In general these only apply when the auxiliary TTL output mode is set to 1 (TTL T) and when the SPIM state machine is not running. + + output (X) selects which logical laser is on when the SPIM state machine is not running. ​ The exact hardware output depends on bits 0-2 of the LED Z setting. ​ X=0 means neither laser is on, X=1 means the Side0 laser is on, X=2 means the Side1 laser is on, and X=3 means both lasers are on (LED Y setting applies in this case). ​ Requires TTL T (aux_IO_mode) setting to be 1.  Setting is overridden during SPIM state machine operation. + + switch_time (Y) sets the switching time in ms between the laser outputs when the SPIM state machine is not running and when both lasers are active per the LED X command. ​ Used to simulate the effect of a passive 50/50 beam splitter, which is particularly useful during alignment. ​ Default is 10ms, cannot be set less than 1ms. + + laser_mode (Z) determines the behavior of the laser TTL outputs, both when using the LED settings and also during the SPIM state machine. + * Bits 0-2 form a code 0-7 selecting how the logical laser outputs are converted to physical TTL outputs. ​ Setting should correspond to the physical hardware connected to the laser TTL outputs. ​ Specifically + * code 0 for individual laser shutters for the two sides (default until v3.01) + * code 1 for single laser with side switch (Side0 is laser shutter for both sides and Side1 is high when the second side is active) (default v3.01+) + * code 2 for Side0 high when the first side of SPIM is active, Side1 high when the second side of SPIM is active + * code 3 for single laser (Side0) automatically turned on during a FAST_CIRCLES move + * codes 4-7 are reserved for future use + * Bits 3-7 are reserved for future use and currently cannot be set + + + Side0_state (R) can be set to 1 or 0 as shorthand for turning on/off the Side0 laser without affecting the state of the Side1 laser. ​ It is equivalent to querying the logical laser output state (X), changing the LSB, and then setting the output state (X).  Introduced in v3.11. + + Side1_state (T) can be set to 1 or 0 as shorthand for turning on/off the Side1 laser without affecting the state of the Side0 laser. ​ It is equivalent to querying the logical laser output state (X), changing the 2nd bit, and then setting the output state (X).  Introduced in v3.11. + + + <-- + + + --> On MS2000 or RM2000# + + + ^Format ​ |LED X=[1 to 100] Y=[0 or 1] Z=[0 or 1] F=[0 or 1]  | + ^Type    |Percentage between 0 and 100 | + ^Remembered |Using SS Z | + ^Firmware Required |LED DIMMER ​  | + + X argument sets the brightness of ASIs LED illuminator by generating PWM thru TTL out.

Instead of using PWM to dim the LED, DUAL LED varies the current applied to dim the LEDs resulting in very little flicker even at high shutter speeds. The brightness of the two LEDs can be independently set using the X and Y arguments of the LED command. At 100% brightness about 900ma is applied. Dual LED have a current limiting feature, user can set the maximum allowed brightness of the two LEDs with R and T arguments. This setting is saved in a non volatile memory on the PCB , so this setting is preserved even after firmware upgrade. Say a LED with maximum rated current is 100ma attached to channel 1. Then setting LED R=10 ​ will limit the maximum applied current to 90ma. + + + X sets the brightness for LED connected to channel 1,\\ + Y sets the brightness for LED connected to channel 2,\\ + R sets the maximum brightness for LED connected to channel 1, and\\ + T sets the maximum brightness for LED connected to channel 2.\\ + + + **Example** + + <​asi>​$LED X=10 Y=50 + :​A​ + Sets the Brightness of LED connected to Channel #1 to be 10% , Channel #2 to be 50% . + + <​asi>​$ LED X?
