What causes 'Buffer Overflow' on Omron Touch terminals?
If you receive a "Buffer Overflow" error on your Omron Touch terminal, it means the NT20S receive buffer is full. To resolve this, lengthen the command transmission intervals. If the error occurs frequently, set flow control for communications.
What does 'NAK Received' mean on Omron Touch terminals?
If you are getting a "NAK Received" error (with an end code displayed) on your Omron Touch terminal, it suggests that noise is causing data corruption during communication. Use a noise-resistant cable if communication occurs in an environment with high levels of noise.
How to resolve FCS Error on Omron Touch terminals?
If you receive a "FCS Error" on your Omron Touch terminal, it may be due to the PC transmitting incorrect data. Check PC operation. It could also be due to noise causing data corruption during communication; in that case, use a noise-resistant cable if communication occurs in an environment with high levels of noise.
Why is the QQ command not available on Omron NT20S?
If the QQ command is not available on your Omron Touch terminal, it means that the PC cannot be connected to the NT20S. Select a type of PC that can be connected to the NT20S.
