Product Overview
The GE IC690USB901 Programming Cable is an industrial automation programming and communication accessory intended to provide a connection between compatible GE control equipment and a programming or engineering workstation.
Programming cables are essential during PLC commissioning, application development, maintenance, diagnostics, parameter management, and system troubleshooting. A reliable connection allows an engineer or technician to establish communication with the controller, transfer or monitor control programs, review diagnostic information, and perform maintenance activities.
The IC690USB901 has a specified cable length of 2.8 meters and a shipping weight of 3 kg.
Because a programming cable forms the physical connection between an engineering computer and industrial control equipment, correct connector identification, compatible software, communication configuration, driver installation, and proper cable handling are important for reliable operation.
This guide covers installation, connection, commissioning, troubleshooting, maintenance, and practical application considerations for the GE IC690USB901.

Role in PLC Engineering
A programming cable is often used at several stages of an automation project’s life cycle.
Engineering
During application development, engineers can use the programming connection to transfer and test control logic.
Commissioning
During machine startup, technicians can use the connection to:
- Monitor PLC operation
- Check controller status
- Review diagnostic information
- Test control sequences
- Verify I/O behavior
Maintenance
During production maintenance, the programming connection can help technicians identify controller faults and inspect system behavior.
Troubleshooting
When a machine stops unexpectedly, online access can provide useful information about:
- Controller status
- Program execution
- Diagnostic conditions
- I/O states
- Communication conditions
- Control logic
Cable Construction and Physical Considerations
The specified cable length is:
2.8 meters
This provides useful working distance between the engineering computer and the controller while keeping the connection relatively manageable inside or around a control cabinet.
The cable should be routed carefully to prevent:
- Excessive bending
- Mechanical stress
- Crushing
- Abrasion
- Connector tension
- Exposure to excessive heat
Do not use the cable as a lifting device or allow its weight to hang from a connector.
Installation Guide
Step 1 – Confirm the Cable Model
Verify:
GE IC690USB901
Do not substitute an unidentified cable simply because its connectors appear physically similar.
Programming cables may differ in:
- Pin assignment
- Communication electronics
- Protocol
- Electrical levels
- Driver requirements
- Controller compatibility
Step 2 – Identify the Controller
Before connecting the cable, identify the exact controller or automation equipment being programmed.
Record:
- Controller model
- Controller series
- Communication interface
- Programming software
- Existing communication configuration
Confirm that the IC690USB901 is suitable for the intended controller.
Step 3 – Prepare the Engineering Computer
The engineering workstation should have the required programming or configuration software installed.
Depending on the control system, verify:
- Programming software
- Communication drivers
- USB drivers where applicable
- Controller support
- User permissions
- Communication settings
If the computer does not recognize the cable, check the operating-system device status before assuming that the cable has failed.
Step 4 – Inspect the Cable
Before connection, inspect the complete cable.
Check:
- Connector housing
- Pins
- Cable jacket
- Strain relief
- Connector locking mechanism
- Signs of corrosion
- Cuts
- Crushing
- Abrasion
- Excessive bending
Do not use a cable with exposed conductors or visibly damaged connectors.
Step 5 – Connect the Cable
Connect the appropriate end to the engineering workstation and the compatible end to the controller.
Ensure that:
- The connector is fully inserted.
- The connector is correctly oriented.
- No excessive force is applied.
- The cable is not under mechanical tension.
Do not force a connector that does not fit.
Step 6 – Establish Communication
After connection:
- Start the programming software.
- Select the appropriate controller.
- Select the programming interface.
- Configure the required communication settings.
- Attempt to establish an online connection.
- Verify controller identification.
If communication is successful, confirm that the software identifies the intended controller.
Step 7 – Verify the Controller Before Editing
Before making any changes:
- Upload or back up the existing program where appropriate.
- Save configuration information.
- Record important parameters.
- Verify the correct controller.
- Confirm the correct project file.
This is especially important in facilities containing multiple similar PLC systems.
Programming and Commissioning
Program Upload
A programming cable can be used to retrieve an existing controller program where the controller and software support the operation.
Before uploading:
- Identify the correct controller.
- Establish communication.
- Confirm the controller status.
- Save the retrieved project.

- Excessive bending
- High temperatures
- Chemical exposure
- Oil contamination
- Water
- Repeated connector stress
If the cable must cross a cabinet edge, use suitable cable protection.
Maintenance Procedure
Visual Inspection
Inspect the cable periodically for:
- Cuts
- Cracks
- Abrasion
- Connector damage
- Bent pins
- Corrosion
- Loose strain relief
- Deformation
Connector Maintenance
Keep connectors clean and dry.
Do not use excessive force when inserting or removing connectors.
When disconnecting:
- Stop active programming operations.
- Confirm the controller is in a safe state.
- Disconnect the connector correctly.
- Protect the connector from contamination.
- Store the cable appropriately.
Storage
When not in use, store the IC690USB901 in a clean, dry location.
Avoid:
- Tight loops
- Sharp bends
- Heavy objects placed on the cable
- High humidity
- Excessive heat
- Direct sunlight
- Chemical contamination
The cable should be coiled loosely rather than tightly wrapped.
Preventive Maintenance Table
| Maintenance Area | Recommended Action |
|---|---|
| Cable Jacket | Inspect for cuts and abrasion |
| Connectors | Inspect for damage |
| Pins | Check for contamination or bending |
| Strain Relief | Inspect for separation |
| Cable Routing | Avoid sharp edges and high-noise areas |

A connector should fit naturally. Excessive force can damage both the cable and controller interface.
Routing Next to High-Noise Cables
Industrial electrical noise can interfere with communication.
Allowing Connector Strain
Do not allow the 2.8-meter cable to pull downward on the controller or computer connector.
Downloading the Wrong PLC Program
Always verify the project and controller before downloading.
Programming a Live Machine Without a Safety Check
Before making program changes, ensure that the machine is in a suitable safe state.
Failing to Back Up the Existing Program
Always preserve the current project and configuration before making significant changes.
