This article covers Xiegu CE-19 データインターフェース拡張カード G90.

Overview

The Xiegu CE-19 Data Interface Expansion Card is a dedicated accessory for Xiegu transceivers like the X5105, G90, and G1M. It adds an extended ACC port that allows you to connect your radio to a PC or modem for digital modes, remote control, or amplifier integration. Weighing just 0.2 kg and featuring a compact blue PCB, it's designed to sit neatly alongside your transceiver. Built-in digital isolation technology ensures clean signal transmission between the radio and computer, even when operating at different power levels. When paired with the XPA125B 100W amplifier, the CE-19 becomes the central hub for upgrading from QRP to full-power operation.

Connectivity & Compatibility

The CE-19 plugs directly into the Mini-DIN8 ACC port on compatible Xiegu transceivers. It breaks out the signals into two separate paths: a set of 3.5mm stereo jacks for audio I/O (line in/out) and a Mini-DIN6 connector for the XPA125B power amplifier. This makes wiring to a PC sound card, external modem, or amplifier straightforward. Included in the box are three audio cables, three 3.5mm stereo plugs, and one 8-pin paired cable. The digital isolation circuitry minimizes ground loops and RF interference, which is especially important when running high power or using a computer with a noisy power supply.

Product Info

Released around 2019, the CE-19 is still widely available through Japan and other retailers. Pricing hovers around ¥7,000–¥8,000. Warranty terms vary by seller, but typically cover 30 days for initial defects. The package contains the CE-19 card, audio cables (×3), 3.5mm stereo plugs (×3), and an 8-pin paired cable (×1). Market positioning: this is a mid-range, brand-specific accessory that is essential for any Xiegu owner who wants to move beyond basic voice operation. There are no direct third-party alternatives that offer the same plug-and-play compatibility.

Best Use Cases

Digital mode enthusiasts: If you want to run FT8, RTTY, or other PC-based digital modes, the CE-19 is the easiest way to connect your Xiegu transceiver to your computer's audio interface. No soldering or custom cables required. QRP operators upgrading to 100W: Pair the CE-19 with the XPA125B amplifier to boost your signal. The card handles both audio and amplifier control signals, so you don't need extra wiring. * Remote station builders: By keeping the transceiver connected to a PC via the CE-19, you can use rig-control software for remote operation. Note: this only works with the listed Xiegu models; other brands are not supported. ## FAQ
Q: Which Xiegu transceivers are compatible with the CE-19? A: Officially supported models are the X5105, G90, G1M, and XPA125B. Other models with the same ACC port pinout may work, but are not guaranteed by the manufacturer. Q: Do I need to install drivers for the CE-19? A: No. The CE-19 is a passive interface card; it does not require any drivers. Your PC will see the connected audio lines as standard input/output devices. Q: How effective is the digital isolation? A: It significantly reduces ground-loop hum and RF interference between the transceiver and PC. This is especially noticeable during high-power transmissions or when using a laptop with a floating ground.
