H. Slave Mode
For ring-trip applications where heavy usage of the DVA-TNT is expected, multiple units may be configured in master-
slave mode to allow for multi-line capability without having to install additional temperature sensors for each DVA-TNT.

1. Since many PABX's can be programmed to play a message from a single DVA-TNT to several callers at once, you
should determine if a multi-line installation is necessary.
2. Connect the temperature probe to the master unit (pins 9 and 10).
3. Program each unit individually to your desired messages and settings.
4. Connect the I/O communications terminal (pins 5 and 6) of the slaves in parallel to pins 5 and 6 of the master, being
careful to observe polarity.
5. Access the programming mode (see Programming section A) of the master and enter ,,1.
6. Access the programming mode (see Programming section A) of the slaves and enter ,,2.
7. Assign the master unit to the first line in your hunt group. This is important, as the slave's temperature data will
only be updated when the master unit receives a call.
8. Attach the slave units to the subsequent lines in your hunt group.

The DVA-TNT can be set up in several modes of operation, including a time and temperature announcer, a time only
announcer, a temperature only announcer, a standard ring trip announcer, a drum recorder, as well as a night mode
announcer. The normal operating mode is for the main greeting to be given followed by "The time is XX:XX temperature
XX". This basic operation can be customized in Programming.
A. Time and Temperature Announcer
When the DVA-TNT is called, the unit will play a pre-recorded greeting or up to 30 seconds of custom recorded greet-
ing followed by the time and temperature announcement. In addition, 30 seconds of additional announcement may be
used after the time and temperature announcement.
