1. Be sure to use a null modem cable.
2. Verify that Vosponder has +12 VDC on Pin 2 of connector
J1 and that Pin 1 is grounded to the power supply or
datalogger.
3. Go to HyperTerminal and select File | Properties | Connect
To. Make sure that the COM port is the one that you are
connected to on your PC. Now select “Configure” and make
the settings are as follows:
Bits per second: 2400
Data Bits: 8
Parity: None
Stop Bits: 1
Flow Control: Xon / Xoff
ASCII Line Delay = 15 milliseconds
ASCII Character Delay = 20 milliseconds
Problem:
The voice image file does not transfer to the Vosponder
correctly.
Solution:
The terminal program is possibly sending the file across faster
than the Vosponder can receive it and store it. You need to slow
the transfer process down. In HyperTerminal this is done by
going into the File | Properties | Settings Tab |ASCII Settings.
Then make the following changes:
Line Delay = 15 milliseconds
Character Delay = 20 milliseconds
