CHAPTER 2 INSTALLING and SETTING UP THE SNI SHELF
Programming the DTMF Address Decoder
To program the 41632 DTMF Address Decoder, perform the following steps. A unique DTMF
code must be assigned to the Orderwire so only that Orderwire responds to the call.
1. Switch, SW-5, should be set for the number of digits in your code (i.e., 1, 2, 3, or 4
digits). Be sure you have only one setting selected.
2. Switches SW1 through SW4 correspond to digits 1-4 of your code. SW1 through
SW4 are found on the module from right to left, when viewing the board from the
front. Digit 1 – 4 on the switch are labeled from left to right, corresponding to
switch positions 1 – 4. You will need to refer to the chart below to program the
correct codes.
