USB-301A

Description

USB programming/data cable for LS devices (PLC and H100 family drives), the USB-301A programming lead.

The Polar Energy Assessment:

USB-301A is LS’s branded USB programming / service cable used for PC↔device connections (PLC programming, DriveView for H100/H100+ drives, firmware upload/download and commissioning). Tis’ the official LS cable for modern USB-capable controllers and drives; length and exact connector details can vary by stock listing, so confirm the spec for the SKU you buy. It replaces the old RS-232-only approach and usually works plug-and-play with the vendor software once the correct drivers are installed.

Pros

• plug-and-play with LS software
• Replaces problematic RS-232 adapters on modern laptops.
• Handy spare to keep in every service bag for drives and controllers that accept USB programming.

Limitations

• Variants exist (length, connector type); double-check to avoid buying the wrong cable length or pinout.
• Some manufacturer tools still require vendor drivers.

Typical use cases

• Programming and commissioning LS PLCs and drives (H100 / H100+ DriveView), field service, firmware updates, and laptop-based fault diagnostics.
