ATEN LIN5-04A2-J11G Serial RJ11 Cable
Overview
The LIN5-04A2-J11G is a Serial RJ11 cable designed as a direct replacement or supplemental connection component for compatible ATEN 4-port KVM switch installations. If you are provisioning or expanding a rack-mounted KVM deployment that relies on Serial RJ11 signaling for port connectivity, this cable is the correct factory-matched component — sourced as a genuine part to ensure signal integrity and plug compatibility with the target switch's RJ11 port interface.
Compatibility
This cable is matched to ATEN 4-port rack-mount KVM switches that support USB keyboard/mouse input, video up to 2048x1536 with DDC2B, hotkey and pushbutton port selection, and a 1–99 second scan interval — characteristics of the ATEN CS1742/CS1744 product family. Confirm your switch's RJ11 interface matches before ordering; not all ATEN KVM models use the RJ11 Serial connector format. The target switch uses a single DC jack (black) for power and carries 4 orange LED indicators for port-on-line/selected status.
Installation Notes
Install in a 0–80% RH non-condensing environment — the same humidity envelope required by the parent KVM switch. Firmware on compatible switches is field-upgradeable (reference version V1.3.125, dated 2017-09-11); cable replacement does not affect firmware state. No special tools are required for cable seating; standard RJ11 clip retention applies. Verify cable orientation against the switch's labeled port before securing in a rack bundle to avoid signal errors on port scan.
