Figure 5.2; Sample key programming
Using this data, when the 0 key is pressed, the DAI-2 will:
• switch relays 1, 2 and 6 on
• switch relays 3, 4 and 8 off
• relay 6 will be switched on momentarily
• relay 7 will be left alone
• switch the audio monitor so that the program audio feed is sent to the telephone line
• not generate a slate tone
• not make any alarm calls
• not read the status of any logic-level inputs
A complete listing of available settings and descriptions is included in this section along with a complete command
matrix. Some conditions appear in the command matrix that do not make sense. For instance, do not alarm calls with
a key press–trigger alarm calls only with a logic-level input. When the dialing sequence starts, it is likely that you will
be disconnected from the DAI-2 if alarm calls are triggered by a key press.
Plan your settings carefully before you begin the process of programming. Watch for cases where two key presses
will have conflicting results on a relay. Remember that audio and relays can be left alone on certain key presses by
programming "no change" conditions.
Suppose you want to change the command matrix so that relay 3 switches on when the 0 key is pressed.
• invoke the programming write mode by pressing ❊ -8
• the DAI-2 responds with one long tone to prompt for the programming security code
• enter the programming security code: 1266
• the DAI-2 responds with two short beeps to confirm that it is in programming write mode
• enter the three digit address for the data you want to change: 002
• enter the new data value for this address: 1
• press # to write the new data to the address
• the DAI-2 responds with one short beep confirming that it wrote a 1
• enter ❊ -❊ to exit the programming mode
The address 002 came from the command matrix at the point where the 0 key and relay 3 meet. The command value
to turn the relay on (1) is given in a chart later in this section.
