Abstract

A network arrangement uses a poll select control protocol and a loop back arrangement at each node for equalizing transmission delay from each node to a central station. Delays at each node can be adjusted to start timing in response to a broadcast signal indicating an amount of delay to be applied from the start of a synchronization interval to the beginning of transmission of data collected at the nodes. The arrangement is particularly useful in the field of data acquisition and particularly in the area of seismic sensing.
