Deterministic Network Cable Diagnostic Functions
The 1788-MCHKR provides direct electrical verification of industrial network media by applying cable test routines across multiple communication standards. The unit supports Ethernet UTP/FTP cables, ControlNet coaxial cables, DeviceNet trunk and drop cables, DH+ communication cables, and Remote I/O cable types.
The diagnostic operation includes cable failure identification, wire mapping, and cable length measurement. The handheld interface displays test results through a two-line LCD, allowing field verification without connection to a controller or programming workstation.
For Allen-Bradley industrial control networks, the media checker supports physical layer inspection associated with EtherNet/IP deterministic networks, ControlNet coaxial links, and legacy DH+/RIO communication infrastructure. The device is used to verify network media integrity before controller-level communication troubleshooting.
Frequently Asked Questions
Q: Does the 1788-MCHKR require external power during cable testing?
A: No. The device operates from two AA 1.5 V alkaline batteries and provides portable cable diagnostic operation.
Q: Which physical interfaces are available for cable connection?
A: The device provides RJ45, DB-9, and BNC input connectors for Ethernet, DH+/RIO, ControlNet, and related network media testing.
Q: Can the device measure Ethernet cable length?
A: Yes. The 1788-MCHKR supports Ethernet cable length measurement from 1 m to 350 m with 0.5 m resolution.
Field Installation Guidelines
- Disconnect communication cables from active network equipment before performing cable diagnostics.
- Confirm the selected test mode matches the connected cable type before initiating measurement.
- Maintain proper shielding practices when testing shielded twisted pair (STP) and coaxial communication cables.
- Avoid connecting the unit to energized communication circuits unless the network design permits passive diagnostic connection.
- Store the device with batteries removed if extended storage conditions are expected.
- Verify connector condition on RJ45, DB-9, and BNC interfaces before field testing.
