2.1  Power

 

● An AC voltage appears between TP10/TP11 and TP12/TP13 when 

the hand crank is activated. This voltage is rectified in D19 and D21, 

providing DC power for two purposes: 

 -

Powering the amplifier

 -

Creating a call signal

 

L

P8 and P9 together with D17 enables the use of the board with the old inductor.

 

● When a call is being made, the actual line will carry a generated 

voltage. This voltage is fed through the active line via the 

corresponding diode D11 and D12 to the amplifier. 

 

● A permanent amplifier 24 VDC power can be supplied on the 

connection block terminal 23 (+) and 24 (-).

 

L

To avoid noise problems, the 24 VDC power supply must be connected via a DC/

DC converter.

 

L

Note that the circuit boards can be used as spare parts for the older VSP units. 

When using boards with inductors, remove jumpers from pins J6 and J7/J8 and 

insert a jumper on pin J9 located to the left of the DIP switches.

2.2  Calling

 

● The station’s extension number is set by DIP switches P11 - P22. 

 

This will activate the call signal generator in the called station and 

provide power to the amplifier.

 

● The desired station is selected by a 12-way rotary switch.

 

When turning the hand crank, a voltage is supplied to the selected 

line.
