Cryptograf 

    

Cryptograf features 4 address inputs, 1, 2, 4 and 8, each of which has an associated input socket as 
well as a 3 position state switch which allows each address input to be held high, respond to input 
signals, or held low.  

Each input has two status LEDs. The red LED displays the signal present at the input socket, while the 
green LED displays the status of the address input.  

The combination of signals present at the input sockets, together with the positions of the state 
switches allows Cryptograf to have 16 different output states, numbered from 0 through to 15.  

The output state of Cryptograf can be ascertained by observing which of the 4 address inputs are 
high.

From December 2019 these three values have been replaced with 120K, 47K, 47K. If you have an 

older PCB with 100K, 27K, 27K, we recommend that you replace these values with 120K, 47K, 47K.
