Dallas Electronic Keys

• Input of the credit (KEY IN);
• Zeroing of the credit (KEY OUT);
• Short accounts department (SHORT STATISTICS);
• Long accounts department (LONG STATISTICS).

• High degree protection against breaking in
• Use of any types of keys DS 909X series
• Shocker resistant
• Simplicity and convenience in operation:
• No necessity to keep bunch of keys;
• one programmed key for input of the credit for all machines.

• indicator,
• driving button,
• micro-controller with energy independent memory for programming and keeping information about 5 electronic identificators in it.

• It is possible to establish the device in any slot machine having standard electromechanical keys. No highly skilled experts required for installation.
• ?there are no mechanical elements in the device which can wear out.
  Unlike a mechanical key,
  It is easier to place an electronic key to the input reader.
• on outputs of a payment there will be no tinkling sound of contacts peculiar to buttons and mechanical keys, therefore payments of slot machines will work more reliably and more correctly.
• protection against not authorized access:
  careless players often cannot resist temptation to reach a cord going to the electromechanical lock to connect outline wires to get themselves not paid credit.
  Not having a corresponding key, nobody can cause you damage even if will reach a desired wire.

1. Controller board together with the pipeline
2. Reader
3. Wiring for connection

1. Connect the device in conformity with connection scheme in the appendix.
2. The device works in one of two modes:
   -mode of recognition of electronic identifiers
   -mode of programming (can be programmed up to five electronic identifiers of DS199X type).
3. At energization the device is in a mode of recognition; the point on the indicator is shone.
4. The microcontroller interrogates the input reader and if the code of the electronic identifier coincides with a code programmed for one five channels on a corresponding line the operating signal of a low level stands out and remains there until the electronic identifier contacts the input reader.
5. 4 and 5 channels remain closed up until a repeated touch of a key is made.
6. In other cases outputs of lines are in the third condition (open collector).

1. For programming of any channel on the certain electronic identifier it is necessary to choose this channel by consecutive search by means of button K1.
2. By each pressing of the button the indicator highlights number of the channel for a few seconds; it is necessary to bring the electronic identifier to the input reader.
3. After this the scheme passes in a mode of scanning.
4. Having chosen the necessary channel, bring the electronic identifier to the input reader.
5. The microcontroller reads code of the identifier and writes it down in non-volatile memory.
6. If process has passed successfully 4 bottom segments of the indicator light up and gleam until the button is pressed.
7. By following pressing of the button the following channel is chosen.
8. If at reading of code there was a failure letter "?" will be highlighted on the indicator and will gleam until the button is pressed.
9. By following pressing of the button the same channel is chosen.
