Below are listed the various programming commands for the DT8 DTMF controller board. All commands are entered using a DTMF keypad or a standard touch-tone telephone (not supplied).
To enter programming mode remove power from the DT8, close the programming link, and reapply power to the DT8 board. On power up three beeps will be heard from the piezo alarm - the DT8 is now in programming mode.
After programming the DT8 to your requirements turn off the power, remove the programming link and then reapply power. The DT8 is now ready for use.
Determine how you want to programme the DT8 using the tables below. For instance if you want to programme relay 5 to use pulse mode with a pulse of 4.7 seconds then the programming sequence would be * 5 1 4 7 #. Or if you wanted relay 5 to use latch mode and to be operated on power up then the sequence would be * 5 2 0 1 #.
When entering the programming sequence the piezo will beep to indicate progress as follows:
1) after pressing the * key three beeps will be heard to indicate
the beginning of the sequence
2) each valid digit key will produce a single beep
3) after pressing the final # key three beeps will be heard to
indicate the acceptance of the sequence this is followed by a brief
silence and then three more beeps to indicate ready
4) if a wrong key is pressed during the sequence a long error beep will
be heard followed by a brief silence and then three more beeps to indicate
ready, any previous setting is unaffected.
Note:
There is no time out period between key presses.
A sequence may be aborted by pressing the * key.
Follow Mode
* N 1 # or * N 1 0 0 # |
N = 1 to 8. |
comments |
Relay N operates when DTMF tone N is received. |
Pulse Mode
* N 1 T T # | N = 1 to 8. TT = Pulse period 0.1 to 9.9 Seconds in 0.1 second steps. |
comments
|
When DTMF tone N is received relay N operates and stays operated for the length of the programmed pulse period. |
Latch Mode
* N 2 0 S #
|
N = 1 to 8. S = 0 = Relay off at power up. S = 1 = Relay on at power up |
comments
|
When DTMF tone N is received followed by DTMF * the
relay N is operated and stays operated until reset with N #. Note: Any relay can be programmed to operate on power up or restart |
Exclusive Mode
* N 2 1 S # | N = 1 to 8. S = 0 = Relay off at power up. S = 1 = Relay on at power up |
comments
|
Any or all relays can be in the exclusive list. When tone N is
received relay N is operated and all other relays in the exclusive
list are released. Only one relay in the exclusive list can be
operated at any one time. |
Set/Reset All
* 0 1 # |
Set All and Reset all disabled Both commands give identical results. |
* 0 1 S R # |
S = 0 = Set All disabled |
Lock code
* * N N # | Where NN means between 1 and 8 digits (DTMF numbers 0 to 9, letters A to D) |
* * # | No lock code set - cannot lock unit |
comments | When the DT8 receives a valid lock code it cannot be activated by any more commands until after it has received a valid unlock code. |
Unlock code
* # N N # | Where NN means between 1 and 8 digits (DTMF numbers 0 to 9, letters A to D) |
* # # | No unlock code set - use lock code as unlock code |
comments |
The unlock command works in conjuction with the auto-lock feature |
Inter-tone timing
* 9 0 # |
Inter-tone timing disabled Both commands give identical results. |
* 9 0 T T # | Inter-tone timing enabled TT = 0.1 to 9.9 seconds in 0.1 second steps |
comments | Don't make the timing period too short otherwise you won't have time to send the tones - recommend minimum 05 = 0.5 seconds. When disabled the DT8 will never time out if a command is not completed. If you require a long time between tones then we recommend you set the timer to 99 = 9.9 seconds. |
Auto-lock feature
* 9 1 # |
Auto-lock disabled |
* 9 1 0 0 # |
Auto-lock immediate - After receiving a valid unlock code the DT8 will respond to only one command after which it is automatically locked again. |
* 9 1 T T # | Auto-lock timed - TT = 0.1 to 9.9 minutes
in 0.1 minute steps After receiving a valid unlock code the DT8 will respond to all further commands unless the timer period of inactivity is exceeded, after which the DT8 will not respond to any commands except the unlock command. |
comments | The auto-lock feature works in conjuction with the unlock command. |
Audio Feedback feature
* 9 2 # |
Audio Feedback disabled |
* 9 2 F S # |
Where F = 0, 2 or 3 and S = 0, 2 or 3 |
comments |
If you don't require Audio Feedback then disable it (make F =
0) - otherwise it slows down operation of the unit. |
Access codes
* 9 3 # | Individual Access code disabled |
* 9 3 A A # |
Individual Access code enabled - AA = digits 0 to 9 or
Alpha A to D |
* 9 4 # | Group Access code disabled |
* 9 4 A A # |
Group Access code enabled - AA = digits 0 to 9 or Alpha
A to D |
* 9 5 # | Allcall Access code disabled |
* 9 5 A A # | Allcall Access code enabled - AA = digits 0
to 9 or Alpha A to D When set the unit requires to see the access code AA before any command. The unit needs to be unlocked for access to work. Audio Feedback is not generated. Any number of units may share the Allcall Access code. The Allcall Access code may be used as a secondary Group Access code if required. |
comments |
Audio feedback (if enabled) only works with Individual Access codes and is restricted to Command Completion, Lock and Unlock codes |
