The Allen-Bradley 1770-KF3 communication interface module has a power consumption of 5 Watts maximum. The 1770-KF3 communication interface module interacts with the host computer via an RS-232C link by the use of a half-duplex or full-duplex DFI protocol. The 1770-KF3 module links the host computer with nodes on the Data Highway 485 network. The Data Highway 485 network provides a data communication rate of up to 19,200 baud, the capacity for the interconnection of up to 32 nodes, slave devices, and support for 4,000 feet of maximum cable length. It also makes it possible to remove or add nodes without causing network disruption, and it has multi-master capability and token-passing access control for further flexibility.

When installing the Allen-Bradley 1770-KF3 communication interface module, the users need to follow specific steps. First, they need to have a description of their network requirements. Second, they need to set up the required cables. Third, they need to prepare and complete the network setup properly. Fourth, they need to know their applications' correct voltage level and configure the voltage selector for the Allen-Bradley 1770-KF3 communication interface module. The users can change the power cord if necessary. Finally, the users need to take note of the default configuration parameters of the Allen-Bradley 1770-KF3 modules and adjust those that do not match their applications. The Allen-Bradley 1770-KF3 communication interface module has an ambient operating temperature range from 0 to 60 degrees Celsius (32 to 165 degrees Fahrenheit) and an ambient storage temperature range between -40 and 85 degrees Celsius (-40 and 210 degrees Fahrenheit). It has a non-condensing ambient humidity range from 5 to 95%. The module has dimensions of 9.5 inches (24.1 centimeters) x 7.1 inches (18.0 centimeters) long x 2.4 inches (6.1 centimeters) and a weight of approximately 2 pounds (0.9 kilograms).
