Number of Retry Attempts
You can set the machine to automatically try to resend data when the data cannot be sent. This may occur because the receiver is busy sending or receiving, or when an error occurs. This setting determines the number of retry attempts. You can set from one to five retry attempts, or select '0' to turn the Retry Times mode 'Off'.
