6.16.2. Digital Outputs
The DO command can be used to set the output voltage of all available digital
outputs. The DO value must be within the range of 0-255.
Digital output values can also be referenced one bit at a time with the
DO[1-8]
commands. Note that the indexes are 1-based for the bit references. For
example, DO1 refers to bit 0, not bit 1. See table 6.4 for details.

If a digital output is turned on, the corresponding bit of the
DO command is 1.
Otherwise, the bit status is 0. The voltage level of the digital output when it is on
or off is determined by the polarity setting. See section 6.21 for details.
The initial state of the digital outputs can be defined by setting the
DOBOOT
register to the desired initial digital output value. The DOBOOT value must be
within the range of 0-255. The value is stored to flash memory once the STORE
command is issued.

6.17. High Speed Latch Inputs
The PMX-4EX-SA module provides the following high speed position latch
inputs. This feature will allow the controller to perform a high speed position
capture of both pulse and encoder counters based on a digital input trigger.
Each axis has a designated digital input to perform a high speed position latch.
See corresponding latch input for each axis below in table 6.5.
