The voice terminal must be on a 2-wire port. Refer to the connection diagram and the following instructions.
Voice terminal data is supplied to the DAC unit through a bridged connection on pair 1of the line cord.
The DAC unit is powered by a 12vdc 800ma power supply. Voice terminal data is supplied by the MA24.
The DAC has a LED indicator on the top near the power jack. This LED indicator glows red when it detects the voice terminal data. It requires 30 seconds or more to synchronize properly for data detection. Verify that this LED is turned on. If it is not, recheck the telephone connection, and verify that the telephone is still working.
When the telephone set goes off hook, the DAC red LED indicator changes to green. This indicates that the data is valid and the set is in use.
The synthesized audio can be switched from the internal speaker to the telephone handset.
If the VS100 is used to interface a Callmaster or similar set equipped with a dual prong headset jack, use the MA25 adapter with the MA11 modular cord.
When a call comes in, the audio will not be heard if the handset is on hook. This arrangement works best if a headset is used instead of a handset and the headset is worn continuously. Plug the headset into the dual prong HEADSET jack on the VS100.
When the VS100 is used in the handset mode, the synthesized audio is mixed with the receive audio. The level on the synthesized audio can be adjusted with the volume control. The volume control has no effect on the telephone receive audio.
Make a station to station test call to voice the display. As soon as the called station starts ringing the display is updated with the called station information and the VS100 should voice this information.
The DAC can not detect indicators that were turned on prior to its connection. Therefore it is necessary initially to go off-hook on 2 different line buttons to properly update the VS100. This would include a message waiting indicator. If the message waiting indicator was turned on before the DAC was connected then it can not be detected until it cycles off and on, or if it is updated by the PBX. The update data is sent only once per hour. New data is also sent if the telephone set is disconnected and then reconnected.
Setup information must be sent from the VS100 to the DAC using the RS232 connection. The DAC will not output required data until it is properly initialized. Therefore if the units are powered up together or the VS100 is powered up first, it is necessary to initialize the system.
Additional setup information is also initialized in the VS100. These settings define the voice type, speed, and other factors. The setup information loads each time the unit powers up. Refer to the programming section to change the default settings.
The VS100’s primary function is to voice the display messages. A message is voiced once each time the display is updated. The last message may be repeated by entering ** on the VS100 dial.
Line busy or idle conditions can be voiced by inputting the two digit line number using the VS100 dial. A set profile for the voice terminal being used should be checked to learn how the buttons are numbered.
Held lines can be located by entering ## on the VS100 dial. The unit voices the word hold followed by any lines on hold. If no lines are on hold, it will only say hold.
The VS100 can be reset by entering #1. This resets all serial data and LED indicator files. It also results in initializing data to be sent to the DAC unit.
The active LED on the VS100 winks much slower when the unit is in the program mode.
Set the run/program switch to PROGRAM. All variables are stored using 2 digits on the VS100 dial. Digits must be entered within 3 seconds of each other. After all the variables are set, enter *1 to save the selected parameters.
If the selections are not saved, the VS100 will revert to the previous settings after a power failure. Use the test messages to test different voice parameters.
When you are finished programming the voice parameters, set the run/program switch to RUN.
Substitute the indicated digits for x. For example, dial 15 to play test message number 5.
| CODE | FEATURE | DESCRIPTION | SELECTION | DEFAULTS |
| 1x | Test message | Play pre-stored message to test voice parameters | 1 through 7 | |
| 2x | Voice | Select different style voices | 1 through 8 | 1 |
| 3x | Speed | Select slow to fast speed | Zero through 9 | 5 |
| 4x | Tone | Set the tone | 0=bass 1=normal 2=treble |
1 |
| 5x | Reverb | Include some echo | Zero through 9 | 0 |
| 6x | Punctuation | Vary treatment of numbers and punctuation | 1 through 4 | 1 |
| 7x | Articulation | Amount of punctuation emphasis | 1 through 9 | 5 |
| 8x | Frequency | Changes voice characteristics | Zero through 9 | 5 |
| *9 | Defaults | Reset features 2-8 to the factory defaults | n/a | |
| *1 | Save | Save last choice | n/a | |
| #1 | Reset | Reset the processor | n/a |
Selecting feature code *9 sets the following voice parameters:
| CODE | FEATURE | DEFAULT SETTING |
| 2 | voice | 1 |
| 3 | speed | 5 |
| 4 | tone | 1 |
| 5 | reverb | 0 |
| 6 | punctuation | 2 |
| 7 | articulation | 5 |
| 8 | frequency | 5 |
Some sample messages are stored in the unit to allow you to test changes you make to the speech parameters. These messages are not affected by the factory default (*9), or reset (#1) feature codes.
