The 1788-CNCHKR NetChecker is a ControlNet networks checking tool manufactured by Allen-Bradley/Rockwell Automation. This is a hand-held field device powered by batteries (2x1.5V AA). The 1788-CNCHKR NetChecker is designed to help in the troubleshooting and commissioning stages of industrial automation networks that are based on the ControlNet protocol. It is used to validate signal quality on the ControlNet cabling. Note that the device does not read and give conclusions on the content of communication messages, it only evaluates the signal quality through the coaxial cables. Although it does not check message content, it is systematic with signal inspection because it checks signal reflections and noise, rising and falling edge quality and timing, distortion level, Manchester signal encoding violations, minimum message intervals, peak-to-peak amplitude, and the minimum time between messages. If any faults on the network are detected, a piezo buzzer will give an audio indication.
The Allen-Bradley 1788-CNCHKR NetChecker has 8 bi-color (red or green) status indicators on the front. In the upper-right part of the device, the indicator designated as the TRAFFIC indicator shows the network activity and also indicates a low battery condition. In the lower section, the other 7 status indicators are used as bar graph or diagnostic indicators. The device uses batteries, but it also can be supplied with power from an external adapter rated at 5 Volts DC nominal voltage and 0.25 Amps. Batteries usually can withstand 6 hours of continuous device operation. The 1788-CNCHKR NetChecker is designed to operate at 0 to 50 degrees Celsius. Its dimensions are 152 millimeters by 83 millimeters by 33.5 millimeters, and its total weight is 0.25 kilograms.
