6 Operation with Sip and Puff Type SIDs
Driving is via a tube connected to the Omni’s pneumatic input and the User
Switch is used to enter the User Menu or to sequence through the other
functions of the wheelchair. For this type of SID, you may want to consider using
a pneumatic user switch.
There are four sip and puff commands, each of which relates to a drive
direction. The table below shows the relationships.

In addition, the Omni can be programmed so that two pneumatic operations,
made within the period set by the parameter Double Click Time, will mimic a
short operation of the User Switch in Standby.
The standard R-net programming parameter Joystick Orientation may also be
useful when using this type of SID. Refer to the user guide for the programming
method you are using for further details.
Standard control of seating movements is via a Hard Puff or Sip and a Soft Puff
or Sip will select a different seat axis for movement.
If required, it is possible to re-program the Omni to control the seating
movement in alternative ways. Refer to sections Actuator Selection and
Actuator Axes in the Programming Chapter.
For latched operation using this SID type, refer to Latched Operation.
