The AxeMotion
PulseBox NxtG
module has three connectors:
- The
USB cable
must be plugged on the host computer (USB 2.0 connection,
USB 1.1 compatible). Generic driver (no installation).
- The
DB-25 connector
emulates the LPT parallel port
and should be plugged on the motor power stage. To pre-
serve the LPT compatibility, the topology is the same as a
printer port. Therefore,
Clock
&
Dir
signals of the 4 axes
can be located only on pins 2 to 9, and pins 18 to 25 are
grounded. Other signals are freely assignable on the pins
from the application software so they match the power
stage specifications, provided that any LPT output signal
indeed corresponds to an output, and any LPT input signal
corresponds to an input. If managing less than 4 axes, the
pins 2 to 9 that remains available can then be reused for
driving classical binary outputs (except the PWM output
that cannot be assigned to one of these pins 2 to 9.
- An
extension connector
(to solder) at the top of the box provides a ground
pin, 5V pin, and an extra set of 4 outputs and 3 inputs. If the power stage does
not use signals except
Clock
&
Dir
, then it remains possible to manage these
supplementary inputs and outputs, for example to trigger a spindle or connect
sensors.
