• The Transmit Hang Time is set in milliseconds from 0 to 65535. {default
= 539}
o Hang time determines the duration that the Vosponder leaves the
transmitter keyed after speaking.
o The keyboard characters entered here are not echoed to the PC
terminal until an <ENTER> key has been pressed.
• The Busy Sense or COS sets how the Vosponder responds to a channel
busy signal on pin 8 of the radio connector (J6 in Figure 1-1). {default =
N}
o No; any input on this pin is ignored.
o Yes; the Vosponder will speak the voice image when there is a
voltage (3 – 13 Volts) applied to the pin.
o Inverted; the Vosponder responds to the pin if a voltage is absent.
ƒ This means that if power to the radio is lost or the radio is disconnected,
the Vosponder will be stuck in the speak mode. Caution: This option
should not be used under most conditions, because it will tie up the radio
frequency and drain the power supply very quickly.
o If Set to Data, the Vosponder will suspend speech output and
transmitter keying when there is a voltage (3 – 13 Volts) applied to
the pin. This provides a “polite” mode of operation to prevent the unit
from transmitting while the radio channel is busy. This setting can be
used when a single radio or radio frequency is used for both data and
voice transmissions.
o The keyboard characters entered here are not echoed to the PC
terminal until an <ENTER> key has been pressed.
4.2.4 Uploaded Menu (Transfer the Voice Image File)
M:>U
U:>***
From the main menu (M:>) prompt enter a “U” to go to the upload menu then
follow these steps:
1. From the HyperTerminal Transfer drop-down menu select the “Send Text
File” option.
2. Locate and select the voice image file that you have created and want to
transfer onto the Vosponder. Either double-click on the file or select
“Open”.
3. Select “Send” to complete the file transfer to the Vosponder. As the
upload proceeds you will see some characters (!!*<*<) echoed by the
Vosponder for each 64 byte block successfully transferred. If the voice
image file is small, you will only see a few characters. A larger voice
image file will create multiple instances of the characters as it loads. If
you do not get these characters, then you may need to make some changes
to your terminal software settings, see Section 5 - Troubleshooting.
