DTI 2000 Manual e EDITED.doc 11
The DTI 2000 outputs a “High Busy” signal when one or several high priority zones are busy. A
tone-sequence indicates that a text message is being played back. Text message playback normally
stops automatically but manually stopping the function is possible as well by entering the STOP-
function number code (default setting = 0 respectively 00).
6. Macros
The DTI 2000 allows launching macros that are programmed in the DPM 4000 System Manager,
thus providing access to special functions. For example: switching relays, starting and stopping
signals, entering parameters, launching test sequences, and many others. The macro function can
only be accessed from access level 2. No other number selection is accepted if the selected one or
two-digit number represents a macro function. Pressing the asterisk key (*) launches a macro. The
DTI 2000 acknowledges this request with a single tone signal, indicating that it is operational and
ready to accept desired macro command. It sends a two-tone signal, when entering an incorrect
command or if there is any other problem.
7. Cancelling a Function (Break)
Cancelling an announcement is possible using the hash mark key (#) (Break). The current zone
selection is cancelled as well, while the connection to the DTI 2000 is not interrupted. The
appliance acknowledges the request with a single tone signal and it is ready for new entries (a new
zone selection, launching text message playback, triggering macros).
The hash mark key (#) can also be used to clear erroneously made entries. Using the hash mark
key (#) directly after selecting a text, announcement, macro or stop function prohibits the function
from being executed, but erases it instead. The DTI 2000 is ready for new entries.
8. Hang Up / Cancelling a Connection
Using the asterisk key (*) directly after making an announcement or pressing the hash mark key
(#) forces the DTI 2000 to drop the connection and “hang up”. The DTI 2000 also interrupts the
connection when the calling party hangs up. However, in that case, a few busy tone signals are
output via the PA-system, which can be rather disturbing. Therefore, dropping the connection
through the use of the asterisk key (*) is always preferable.
The DTI 2000 can also be configured to automatically drop a connection after a definable period
of time. This is especially useful to prevent the PA-system from being blocked by a telephone
announcement over longer periods or that it is constantly blocked because of malfunction or faulty
connections. The period of time after which the DTI 2000 automatically drops a connection can be
set in a range between 20 seconds and 10 minutes via the internal DIP-switch S203.
Configuring the DTI 2000
The PC Designer software allows custom configuration for the DTI 2000 to match any specific
application. The programming procedure is equivalent to configuring a paging console. Programming
a paging console’s function keys relates to the programming of a call number table for the DTI 2000.
This table holds the assigned functions of up to 100 one or two-digit numbers (0 to 99). The buttons 1
to 99 on a console correspond to the call numbers and the table entries 1 to 99. The 100-key represents
the call number or table entry 0 (respectively 00) and, as standard, another entry in the table is
reserved for the talk function, which can be activated from a telephone set using the asterisk key (*).
