Description

The 1786-CP is an Allen-Bradley ControlNet network access cable engineered to connect a programming terminal, computer, or diagnostic tool directly to an intelligent device on a ControlNet network. Measuring 3.05 m (10 ft) in length, this specialty interface cable plugs into the dedicated Network Access Port (NAP) on compatible ControlNet processors, scanners, or communication adapters to enable real-time system monitoring, parameter configuration, and diagnostic troubleshooting.

Physical Wiring & Internal Pinout

The 1786-CP features customized internal pinout wiring tailored specifically for ControlNet NAP signals rather than a standard straight-through Ethernet pin arrangement. Its 3.05 m flexible assembly allows field maintenance personnel to maintain a safe distance from active control enclosures while establishing serial data links with ControlNet devices.

Operational Guidelines & Application Limits

Designed solely as a single point-of-entry programming access link, the cable routes control and configuration signals directly into a single NAP on a live ControlNet node. It is restricted from serving as a permanent trunk cable, interconnecting two distinct ControlNet cable segments, or linking a scanner module directly to a processor module without proper network architecture.

Installation & Wiring Considerations

Insert the cable connectors firmly into the Network Access Port (NAP) of the host ControlNet device and the serial/communication interface of your programming workstation. Do not connect a single 1786-CP cable to multiple network access ports simultaneously or use it to bridge separate ControlNet segments, as doing so introduces impedance mismatches and potential network communication faults.

Frequently Asked Questions

Q: Can I use the 1786-CP cable to join two standard ControlNet coaxial trunk segments?A: No, the 1786-CP is specifically designed for Network Access Port (NAP) programming connections and must not be used as a structural trunkline segment or bridge.

Q: Is the 1786-CP wired as a standard straight-through RJ-45 patch cable? A: No, the internal pinout of the 1786-CP is non-standard and wired specifically for ControlNet NAP interface signals. Substituting a standard straight-through cable will prevent communication.
