Hi,
I have a diesel fuel pump.
Inside there are several pcb's, made by tokheim.
The controller unit is broken and thrown away, from there are 6 wires (2 wires to a relay) going into a pcb: tokheim PW88A made in 1999.
The main controller is tokheim 2932/2B-94.
I want to know what type of interface this is, (rs485?) And wiring.
and if you have any knowlege how i can control this pump?
Is it possible to use hyperterm?
Are there a protocol that is known?
