and Modifications for 4 digit ON/OFF Operation FIGURE 2 Block Diagram

The audio input is connected at pins '6' and '5' (circuit common). The 3185E is factory set at 10 k input impedance; unbalanced. This audio input may be changed by the customer to have a 600 termination instead of 10 kΩ, and also to be balanced instead of unbalanced. Consult the CUSTOMER OPTION section for more explanation. ‘Set’ Input Connection: The ‘Set’ input is connected at pin 'D', and when pulsed to circuit common will energize the output relay. The output relay will remain energized until the proper 'OFF' code is received or the ‘Reset’ input is pulsed to ground. This input is level sensitive and requires a minimum pulse width of 20 msec. to circuit common to activate or de-activate the output relay. The ‘Set’ input has precedence over all functions except ‘Reset’. If the 3185E's ‘Set’ input is pulsed to circuit common while decoding a code sequence it will clear previous valid digit(s) decoded after the ‘Set’ input returns to a ‘high’ state. ‘Reset’ Input Connection: Momentarily connecting pin 'E' to circuit common will cause the 3185E to reset. This input is level sensitive and requires a minimum pulse of 20 msec. to circuit common to reset the card. The ‘Reset’ input dominates over all other functions. NOTE: The 3185E will ignore all commands or code sequences until the ‘Reset’ input is removed from circuit common. Relay Output Connections: The 3185E provides a dual Form C relay output. The output relay will energize whenever the preprogrammed 'ON' code sequence is received or the ‘Set’ input is momentarily connected to circuit common. If the output relay is set to ‘momentary’, the output relay will activate approximately 40ms after the last valid digit is received and stay on as long as the last valid digit is present. If the output relay is set to ‘latching’, the output relay will remain energized until the programmed ‘OFF’ code sequence is received or the ‘Reset’ input is momentarily connected to circuit common. The dual Form C relay output connections are shown below: RELAY OUTPUT COMMON CONTACT NORMALLY CLOSED CONTACT NORMALLY OPEN CONTACT 1 FORM C 1 9 10 1 FORM C A K L TABLE 1 Power Supply Input: The power supply input is connected to pins '8' (+12 VDC) and '3' (circuit common). The 3185E requires a power supply capable of providing 50mA minimum, and regulation of the +12 volt, ±10 %.

3185E. Install a jumper at position J2 to terminate the audio input in 600 Ω. Consult FIGURE 3 for the J2 jumper location. Input Balanced/Unbalanced: The input may be selected to be balanced or unbalanced. The J1 jumper determines whether the input is balanced or unbalanced. Removing the short from J1 will make the input balanced. Consult FIGURE 3 for the J1 jumper location. 5 Minute Restoral: The 3185E may be selected to restore the output status for a power interruption of less than five minutes. The 3185E is factory set to enable this restoral. The J7 jumper is open. To disable the five minute restoral install a jumper on J7. Consult FIGURE 3 for J7 location. Momentary Output for ON & OFF: This setting provides a momentary output relay activation for both the ON sequence and the OFF sequence. Momentary duration is 1 second. To enable this feature, install both J3 and J4. Output Relay: The output relay on the 3185E may be set in three different modes of operation; latching, momentary or alternate action (toggling). The 3185E is factory set to latching. Being set at latching means the output relay will energize when the pre-programmed 'ON' code is received or the ‘Set’ input is momentarily connected to circuit common. The output relay will remain energized until the preprogrammed 'OFF' code is received or the ‘Reset’ input is momentarily connected to circuit common. When the output relay is programmed to operate in the momentary mode, it will energize for the duration that the last valid digit is present. In the momentary mode the 3185E will not respond to its pre- programmed 'OFF' code. Alternate action programs the relay for latching (toggling) relay output. In this mode the output relay energizes and de-energizes with the same pre-programmed 'ON' code sequence. 10 Second Pulse: If both ‘Set’ and ‘Reset’ are low and the relay mode is ‘momentary’, then when a valid ‘ON’ sequence of digits is received, the relay is turned on for 10 seconds then ‘OFF’ – even if the last tone is still present. The decoder will ignore all tones and ‘Set’ and ‘Reset’ activities during the 10-second period. Applies only to firmware version 80154-1.10 and later.

The first three digits of the code sequence are the same for both 'ON' and 'OFF'. The fourth digit for the 'ON' code sequence is factory set to '*', and the fourth digit for the 'OFF' code sequence is factory set to '#'. The number of digits to decode is determined by jumpers 'J6' and 'J5'. Consult FIGURE 3 page 7 for the location of 'J6' and 'J5'. The programming of jumpers for the number of digits to decode is shown below: NUMBER OF DIGITS JUMPER J6 J5 1 X X 2 X O 3 O X 4 O O TABLE 3 X = JUMPER INSTALLED O = JUMPER REMOVED Fourth Digit ON/OFF: The fourth digit of the 'ON' code sequence and the fourth digit of the 'OFF' code sequence are factory set at '*' and '#' respectively. To enable user selection of the fourth digits, it is necessary to remove resistor ‘R8” and install two additional selection switches, S4 and S5, plus IC A3. When ordering the switches, please use Digital Alert Systems part number ‘9200002’ for each of the two switches and part number ‘9120375’ for the IC required. Consult the PC board layout in Figure 1, on Page 4, for the location of the parts to be removed and inserted.

sequence. 0 through D select the corresponding DTMF digit to be decoded. The letter 'E' on the rotary switch represents the '*' DTMF digit and the letter 'F' on the rotary switch represents the '#' DTMF digit. As stated before, the 3185E is factory set to decode a 4-digit 'ON' code sequence and a 4-digit 'OFF' code sequence. The first three digits of the code sequence are the same for 'ON' and 'OFF' commands. The fourth digit for the 'ON' code sequence is factory set to '*', and the fourth digit for the 'OFF' code sequence is factory set to '#'. It is not necessary to power down the 3185E when you are programming the code sequence. The 3185E program will read the switch settings each time a code sequence is received. Consult FIGURE 1 on page 4 for location of switches and their designations. OPERATION When the 3185E is connected to a DC power source, the Power/Valid Digit LED CR14 on the front edge of the PC board will be illuminated. This LED indicator will continue to illuminate until a valid DTMF digit is detected or DC power is removed from the board. The Valid Sequence LED CR15 will illuminate upon the decoding of a correct DTMF code tone pair in the proper sequence. Upon the fourth correct digit, the output relay activates and the Relay Output LED CR13 illuminates. During the reception of valid DTMF tone pairs in a sequence the 3185E will — after decoding a valid code number — wait for the next valid code in the sequence. If the time between digits is more than 3 seconds, the 3185E will reset and require that the sequence be sent completely again. Operating With a 4-Digit Code: When a 4-digit code sequence is selected on the 3185E the switch program will be as follows: SWITCH 1 = first digit of the code sequence for both 'ON' and 'OFF'. SWITCH 2 = second digit of the code sequence for both 'ON' and 'OFF'. SWITCH 3 = third digit of the code sequence for both 'ON' and 'OFF'. SWITCH 4 = fourth digit of the code sequence for 'ON' (preset to '*' if switch not installed). SWITCH 5 = fourth digit of the code sequence for 'OFF' (preset to '#' if switch not installed). If the 3185E is programmed for momentary relay output or alternating relay action SWITCH 5 is not used for programming.

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. ADJUSTMENT 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.
