Talon
Convenient Adaptor for Standalone Operation of the PC-Hawk
 

  
 

   
 

 

  
 

 
     Although, it is very simple to connect the necessary items to provide PC-Hawk with standalone capability, an additional small board called the “Talon” simplifies this by including a “Reset Switch”, an On-Off switch and 5v regulator on board.
     This means that a wide range of possible power supplies may be used to provide power for the PC-Hawk via the Talon. For example a simple 6v battery pack (or power supply) is all that has to be connected to the Talon which is then connected by the supplied 10 way cable assembly to the PL3 connector on the PC-Hawk to provide all necessary external connections to “Run” the PC-Hawk in standalone mode. The 6v from the battery pack is converted and regulated by Talon to provide a good quality 5v supply suitable for the PC-Hawk. The connection of the Talon to the PC-Hawk is shown below.


 

 

 

 

 

      In the picture above the box to the right is a simple battery box containing 4 AA batteries providing a total of 6v. The positive and negative leads from this box are connected to the correspondingly labelled Talon screw terminals. The Talon is then connected to the PC-Hawk via a 10 way ribbon cable assembly with a standard cable mounting IDC socket at each end. The slide switch on the Talon provides basic On/Off control for the external 6v supply while the (blue) momentary push button provides the “Reset” facility. An on-board LED shows the current power on/off state. The above configuration is all that is required for a fully working sequencer running a pre-loaded control sequence for the 28 switching outputs as provided on the PC-Hawk screw terminals.
     The voltage regulator on board the Talon will “convert” the incoming voltage to the 5v required by PC Hawk within a range of applied voltages. The illustrated 6v example above is the most efficient, but any voltage up to 12v DC may be used as the source supply for the Talon, making it a convenient adaptor for external power supplies etc..
