A process and system is provided for setting up a polling interval for a device that sends a not acknowledged (NAK) signal. The process determines the number of times the device sends a NAK signal before a successful data transfer; and also determines a statistical parameter based on the number of times the NAK signal is received before a successful data transfer; and sets a polling interval for the device based on the statistical parameter. The statistical parameter may be an average, median, maximum or minimum number of times the NAK signal is received before successful data transfer. A polling interval may also be set based upon the number times the NAK signal is received, wherein the polling interval increases with the number of NAK signals. The polling interval may double after every NAK signal.
