Abstract
A control module for controlling a cable pulling or feeding apparatus at one endpoint of a pulling operation and for wirelessly communicating with a cable feeding or pulling apparatus at an opposite endpoint. The control module includes a switch input to receive a start signal from a switch for initiating operation of the apparatus and an equipment output that connects to the pulling/feeding apparatus. A wireless communication interface communicates ready state or stop state messages to the other apparatus to coordinate a pulling operation. The control module operates in one of two modes: endpoint mode or repeater mode. In repeater mode, the control module may be positioned between the endpoints to extend the wireless communications between the endpoints.
