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. ## Claims ### Claim 1 A control arrangement for use in a cable installing system, the cable installing system including a first apparatus located at a first endpoint, and a second apparatus located at a second endpoint, the first and second apparatus together configured to install a cable through a conduit between the first endpoint and the second endpoint, the control arrangement comprising: a first control module located proximate to the first endpoint and operatively coupled to the first apparatus, the first apparatus having an electric motor coupled to a source of power;
