ATEN 2L1715 DB-25 KVM Stacking Cable — 50 ft (15 m)

Overview

The ATEN 2L1715 is a 15 m (50 ft) DB-25 male-to-female KVM stacking cable designed to physically link compatible ATEN KVM switches in a daisy-chain or stacked configuration. When your rack layout spreads switches across multiple rows or cabinets, this cable provides the reach to keep the stacking bus connected without forcing equipment consolidation. The 2L1715 runs a DB-25 male connector on one end and a DB-25 female on the other, covering the full 15 m span in a single black-jacketed run.

Compatibility

This cable is intended for ATEN KVM switches that use the DB-25 stacking interface — primarily legacy and mid-range ATEN matrix and cascade KVM models that expose a DB-25 stacking port. Verify your switch's stacking interface is DB-25 before ordering; ATEN's newer platform families use proprietary daisy-chain connectors that are not DB-25 compatible. If you are building out a KVM switch stack and your existing inter-switch cables are shorter runs, the 2L1715 fills the gap where standard 1.8 m or 3 m stacking cables fall short. It is not a general-purpose DB-25 serial or parallel cable — the pinout is specific to ATEN's stacking bus and should only be used between ATEN-designated stacking ports.

Installation Notes

Route the 15 m cable through cable management before seating either connector — the DB-25 shell does not allow easy re-routing once both ends are locked. Secure the connector thumbscrews finger-tight to avoid stress on the switch's stacking port. At 15 m, keep the cable away from high-voltage power runs to minimize interference on the stacking signal. Confirm your KVM cabling plan accounts for the full daisy-chain distance, as signal degradation accumulates across multiple stacked segments. Review the ATEN switch documentation for maximum supported stacking cable length when chaining more than two units.
