The Opti-Link Control System – Fig 1 

 

The Opti-Link Control System provides a flexible and intuitive 
control interface between the driver and the vehicle’s 
equipment. The complete system typically comprises the 

Opti-

Link Keypad

Keypad Interface Module

 and a data-encoding 

Output/Receiver Module

Supply characteristics: 

Supply voltage: 12Vdc 

Current draw: Maximum (All switches active) 6.8A     Minimum 
(Sleep Mode) 0.01Amps 

Approvals:  

VCA Approved to 72/245/EEC amendment 95/54/EC 

CE Marked  

PITO AES Specification 5 Issue 9 

 

The Keypad Interface Module – Fig 2 

 

The Keypad connects to the 

Keypad Interface Module

 

(

Figure 2

) via a ‘keyboard’ style cable which should be 

secured with a tyrap to the cable tie post after connection. The 
Keypad Interface Module encodes the 

Keypad Module

 status 

and provides power and data output which may be routed to 
individual 

Receiver/Output Modules 

(

Figure 3

) or the 

Woodway Lightbar via copper wire. 

PA volume adjustment

 

can be made from the top of the Interface Module via a blue 
single-turn variable resistor. (See figure 2). To increase the 
volume turn clock wise and anti-clockwise to reduce the 
volume. 

 

 
The Output/Receiver Module – Fig 3 

 

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 9 of the installation information.
