Operating With a 3-Digit Code:
When a 3-digit code sequence is selected on the 3185E the switch program will be as follows:
SWITCH 1 = first digit of code sequence for both 'ON' and 'OFF'.
SWITCH 2 = second digit of code sequence for both 'ON' and 'OFF'.
SWITCH 3 = third digit of code sequence for 'ON'.
SWITCH 4 = third digit of code sequence for 'OFF' (preset to '*' if switch not installed).
If the 3185E is programmed for momentary relay output or alternating relay action SWITCH 4 is not used
for programming.
Operating With a 2-Digit Code:
When a 2-digit code sequence is selected on the 3185E the switch program will be as follows:
SWITCH 1 = first digit of code sequence for both 'ON' and 'OFF'.
SWITCH 2 = second digit of code sequence for 'ON'.
SWITCH 3 = second digit for code sequence for 'OFF'.
If the 3185E is programmed for momentary relay output or alternating relay action SWITCH 3 is not used
for programming.
Operating With a 1-Digit Code:
When a 1-digit code sequence is programmed into the 3185E the switch program is as follows:
SWITCH 1 = first digit of code sequence for 'ON'.
SWITCH 2 = first digit of code sequence for 'OFF'.
If the 3185E is programmed for momentary relay output or alternating relay action SWITCH 2 is not used
for programming.
Potentiometer R12 permits the user to adjust the level of the received DTMF tones. This adjustment
would be made when the received audio levels are too low or too high to permit reliable decoding.
Setting R12 fully counterclockwise will provide -10 dBmV of gain. Setting R12 fully clockwise will provide
+10 dBmV of gain.
Consult FIGURE 3 on page 7 for the location of potentiometer R12.
