1. A multi-link device comprising:
a load tension pin including a sensor configured to measure tension applied to the load tension pin;
network interface hardware;
one or more processors; and
one or more memory modules storing computer readable and executable instructions which, when executed by the one or more processors, cause the multi-link device to:
determine whether the tension measured by the load tension pin exceeds a threshold value;
transmit, by the network interface hardware, a first binary code to a receiver in response to determination that the tension exceeds the threshold value; and
transmit, by the network interface hardware, a second binary code to the receiver in response to determination that the tension becomes less than the threshold value.
