I have device (card dispenser) with TTL and RS-232
But i couldn't understand how to connect outer button to it using TTL interface.
This have to dispense card to the gate.

First of all, i need to power up 13pin and 14pin (voltage 5V)
I think, it should be pin2 and pin3 with fast click (100ms)
Is it right?

 

Hard to tell. You missed the doc for the higher pin numbers.

"Ground sensor available" and "ground sensor". I have no idea what they are talking about.

Usually, I would expect a "logic ground" pin.

"They" say impulse where they could actually mean the input is "edge triggered"

Other guesses for sensor is:

A signal basically says a card is present at the opening then you incrementally dispense the card until the dispense is successful.

"sensor available"" may mean, a card can be inserted.

I'd look for a timing diagram in the documentation.

Hi!
Thank's you for your participation.
I attach all TTL interface specification document for this device, which I found on the Internet.

 

If it's truly a TTL input then you must sink current for a logic-low (typically 1.6mA) and pull it to 5V for logic-high (low current).

If you are using a switch, the close the switch to ground for logic low, and open the switch for logic high (with a 10kΩ pullup resistor to 5V).
