This switch panel is not recommended for use with any other
than specific Woodway Engineering equipment. If the unit is
used with any other system the warranty will be void.
The Opti-Din keypad can be used either as a hand held unit or
fitted into a standard din style dashboard casing. The Opti-Din
Control System provides a flexible and intuitive control interface
between the driver and the vehicle’s equipment. The complete
system typically comprises the Opti-Din Keypad; (hand held
unit supplied with a bracket or the din fitted unit) and a data-
encoding Output/Receiver Module.
The Opti-Din Control System
Supply Characteristics
The Keypad connects directly to the Output/Receiver Module
(left) via an RJ45 connection (Ethernet style).
The Output /Receiver Module decodes the data and activates
the required outputs via a 14-way connector (note that position
14 on this connector is not used). A green ‘Data OK’ led flashes
to indicate that the data link is functioning. The switch outputs
from the Output /Receiver Module interface directly with the low
current control wiring of Woodway-supplied light bars, sirens,
and strobe power supply systems. The outputs may be used to
control high current auxiliary equipment via automotive relays.
The output circuits incorporate back EMF protection eliminating
the need for diodes to be placed across the coils of any relay
used.
The output channels of the Output Receiver module are self
limiting to prevent damage should the load on any channel
exceed approximately 0.5 amps. In order to prevent damage
to the electronics within the receiver the overload protection
operates instantaneously when this current is exceeded. Devices
that contain capacitors will cause high in rush currents which
may cause the unit to self limit. This will be even more evident
when the engine is running due to the higher battery voltage.
We strongly recommend that with the exception of low
current switching Woodway light bars, all devices to be
controlled are connected via relays as shown on page 10
of the installation information.
