2. Install the Omni2 onto the powerchair.
3. Install the SID onto the powerchair.
4. Program the Omni2 to match the SID.
5. Program the Omni2 to suit the user.
6. Program the R-net driving characteristics to suit the user.
The remainder of this chapter is laid-out as above and it is recommended that the sequence is adhered to. If two SIDs are
required, refer to the Advanced Programming chapter.
4 ASSESSING THE USER’S NEEDS
WARNING (HP, IN)
This should only be conducted by a healthcare professional. Curtiss-Wright accept no liability for losses of any kind
resulting in an incorrect assessment of a user’s abilities.

Curtiss-Wright | PG Drives Technology
SK81935-01
16 | R-net Omni2 Technical Manual | Chapter 1 - Installation
4.1 SELECTING THE SID
Selection of the SID for the user is not covered in this document. It is the responsibility of a healthcare professional to assess
the needs of the powerchair user and to select a suitable SID. It is the responsibility of the individual who is installing the SID
and the Omni2 to make sure the two are compatible with each other and the powerchair on which they will be used. If you
are in any doubt contact the SID manufacturer, the powerchair manufacturer and/or Curtiss-Wright. Your powerchair
manufacturer or mobility dealer will be able to advise of the available SIDs for a particular powerchair model.
WARNING (HP, IN)
Due to the electrical output characteristics of many existing, industry-standard, proportional SIDs, it may not be possible to
detect leakage currents between the analogue (proportional) input pins of the Input Section. The following solutions are,
therefore, recommended:
1) Providing additional, environmental protection, for example a rubber boot, to the mated, D-type connectors may
improve the installation in this respect. It is the responsibility of the powerchair and/or SID suppliers to ensure a
suitable risk assessment is carried out for such SIDs. Refer to the declaration of standards for further information
on the impact on compliance.
2) Use of SIDs which have the capability to detect leakage currents across the analogue input pins of the Input
Section.
Curtiss-Wright accept no liability for losses of any kind resulting from the use of proportional SIDs if neither of the above
recommendations are included in the installation.

5 INSTALLING THE OMNI2 ONTO A POWERCHAIR
The Omni2 Display and Input Sections should be fitted to the powerchair using the brackets supplied by the powerchair
manufacturer. If suitable brackets are not available, the diagram below can be used to design your own.
Take care not to over-tighten the fixing screws.
The Omni2 Display Section should be fitted in a position that is suitable for the powerchair user. It is particularly important to
ensure the Omni2’s screen is clearly visible.
NOTE (HP, IN)
Due to its exposed position, Curtiss-Wright strongly recommends that the Omni2 Display Section is fitted to a flexible
mounting system, e.g. a ‘gooseneck’ arrangement. This will help to mitigate damage caused by inadvertent ‘knocks’.
The Omni2 Input Section should be mounted with the ‘D’ type connectors facing downwards. This will help to prevent
moisture / liquid ingress.

5.1 GENERAL CARE
Avoid knocking the control system, especially the Display Section.
When transporting the powerchair, ensure the control system is well protected.
To prolong the life of the control system, keep exposure to extreme conditions to a minimum.
Always clean your control system if it becomes contaminated with food or drink.
NOTE (OP, HP, IN)
When cleaning the control system, use a damp, non-abrasive cloth and washing-up liquid mixed with water. Do not use
abrasive or spirit-based cleaning agents.
6 INSTALLING THE SID ONTO A POWERCHAIR
WARNING (HP, IN)
The SID should be fitted to the powerchair in accordance with the instructions of both the SID and powerchair
manufacturers. Curtiss-Wright accept no liability for losses of any kind resulting from an incorrect installation of a SID.
Because of the wide variety of SIDs available and the constantly changing specifications, it is not practical to provide a
definitive list of SID classifications in this manual. Instead, the healthcare professional may have to contact the SID
manufacturer, the powerchair manufacturer and/or Curtiss-Wright to determine the exact classification of the chosen type of
SID. Further details on each SID type are given in the following sections.
In addition to the SID for controlling the powerchair functions, the Omni2 has facility for the connection of an optional, user
operated On/Off switch. The function of this switch is identical to the On/Off button on the Omni2’s front panel.
Refer to the Specifications chapter for full electrical specifications of the SIDs and On/Off switch.
6.1 CONNECTION OF SID
For single SID operation, always connect the SID to Port 1.
Port 1 comprises:
A stereo 3.5mm / 1/8” jack for the User Switch.
A 9-way input connector with a TRACE standard pin-out.

A Sip and Puff input.
Make sure that all SID connections to the Omni2 are securely mated.
Route and secure all cables and tubes in such a way as to prevent damage by crushing, cutting or snagging.
6.2 USER SWITCH
This input will accept a normally-open switch, a normally-closed switch or a switch incorporating a resistor network. Refer to
the User Switch section in the Programming chapter for further details. For a truly fail-safe system, Curtiss-Wright recommend
that a User Switch incorporating a resistor network is fitted. If one of these is unavailable, a normally-closed User Switch
should be used. This ensures that if the switch becomes accidentally disconnected, the powerchair will default to a stop
condition. If a normally-open switch is used, the responsibility for that decision lies with the healthcare professional.
As a further level of safety, the Omni2 can also detect if the User Switch jack is not properly located. If it is detected that the
jack is not secure, then drive will be prevented. Alternatively, the Omni2 can be programmed to allow slower drive in this
situation, i.e. a limp home facility, or to allow full drive. Refer to the Switch Detect section in the Programming chapter for
further details.
WARNING (HP, IN)
For a truly fail-safe system, Curtiss-Wright recommend that a User Switch incorporating a resistor network is fitted. If one
of these is unavailable, a normally-closed User Switch should be used. This ensures that if the switch becomes accidentally
disconnected, the powerchair will default to a stop condition. If a normally-open switch is used, the responsibility for that
decision lies with the healthcare professional. Curtiss-Wright accept no liability for any losses resulting from the use of a
normally-open User Switch.
WARNING (HP, IN)
Because a disconnected User Switch means there is no emergency-stop function, Curtiss-Wright recommend that Switch
Detect is always set to On. Curtiss-Wright will accept no liability for any losses resulting from any other setting of this
parameter.
6.3 D-TYPE CONNECTOR
Ensure the connector is correctly inserted and if there are locking screws ensure they are fully tightened.
Some SIDs will have a ‘detect-link’ fitted. This link enables the Omni2 to detect if the D-type connector has become
disconnected. The Omni2 will need to be programmed to look for a ‘detect-link’. Refer to the 9-way Detect section in the
Programming chapter for further details. To enhance the system safety and to ease diagnostics, it is recommended that this
feature be used if the SID has such a link. If this feature is used and the Omni2 detects the SID is disconnected, a screen as
below will appear.

Some SID/User Switch installations require a permanent 12V power supply, even while the Omni2 is asleep; whereas, to save
power, some installations would want to switch off this supply while the Omni2 is asleep. Consequently, there is a
programmable parameter, Sleep 12V, which sets this operation. Refer to the Sleep 12V section in the Programming chapter
for further details.
WARNING (HP, IN)
The SID’s D-type connector should always be fitted with gold contacts and a suitable backshell with locking screws. The
locking screws should be used to mechanically hold the connector in place. Curtiss-Wright accept no liability for losses of
any kind if these conditions are not met.
6.4 SIP AND PUFF INPUT
Ensure the tube from the Sip and Puff Device is of the correct diameter and that it is securely routed. For pneumatic details of
this input, refer to the Specifications chapter.
7 HOW TO SET-UP THE OMNI2
There are two methods of programming the Omni2. Details of the actual programmable parameters are given in the
Programming chapter.
7.1 ON-BOARD PROGRAMMING (OBP)
This is performed using the Omni2’s own display and front panel buttons. For details of these buttons, refer to the Controls
and Connections section. From the Omni2, all system OBP parameters can be adjusted: for example, Speeds and
Accelerations.
OBP can be entered in one of two ways, depending on the factory programming of the control system.
