3. Setup and Connection

The CE-19 card expands the ACC port of your Xiegu transceiver, providing dedicated ports for Audio Frequency (AF), Data, and Push-To-Talk (PTT) control. Proper connection is crucial for stable operation.

3.1. Understanding the CE-19 Ports

The CE-19 features several connection points:

"FROM X5105" (8-pin Mini-DIN): Connects to the ACC port of compatible Xiegu transceivers (G90, G1M, X5105).
"TO XPA125" (6-pin Mini-DIN): Connects to the XPA125B amplifier.
AF CON (3.5mm sockets): Audio Frequency input and output for connecting to a computer sound card.
DATA CON (3.5mm sockets): Data input and output for digital modes.
PTT CON (3.5mm socket): Push-To-Talk control for external devices or amplifiers.

CE-19 Mini-DIN Ports — Figure 3: Close-up of the CE-19's Mini-DIN ports. The image highlights the 6-pin Mini-DIN port labeled "TO XPA125" and the 8-pin Mini-DIN port labeled "FROM X5105", which are used for connecting to the amplifier and transceiver, respectively.

CE-19 PTT CON 3.5mm Socket — Figure 4: Close-up of the CE-19's PTT CON 3.5mm socket. This port is used for Push-To-Talk control.

CE-19 AF CON and DATA CON 3.5mm Sockets — Figure 5: Close-up of the CE-19's AF CON and DATA CON 3.5mm sockets. These ports provide audio frequency input/output and data input/output for connecting to external devices.

3.2. Connecting to a Xiegu Transceiver (G90, G1M, X5105)

Use the provided 8-pin pair cable to connect the "FROM X5105" port on the CE-19 to the ACC port of your Xiegu G90, G1M, or X5105 transceiver.

CE-19 Connection to Xiegu G90 — Figure 6: Connection diagram for Xiegu G90. This diagram illustrates how the CE-19 connects to the G90 transceiver via its 8-pin ACC port and then to the XPA125 amplifier via the 6-pin port.

CE-19 Connection to Xiegu G1M — Figure 7: Connection diagram for Xiegu G1M. This diagram shows the CE-19 connecting to the G1M transceiver's 8-pin ACC port and subsequently to the XPA125 amplifier.

CE-19 Connection to Xiegu X5105 — Figure 8: Connection diagram for Xiegu X5105. This diagram details the connection of the CE-19 to the X5105 transceiver's 8-pin ACC port and its further connection to the XPA125 amplifier.

3.3. Connecting to the XPA125B Amplifier

Connect the "TO XPA125" 6-pin Mini-DIN port on the CE-19 to the corresponding input on your XPA125B amplifier. This enables the transceiver to control the amplifier's PTT and band data.

3.4. Connecting to a Computer for Digital Modes

For digital modes (e.g., FT8, PSK31), you will need to connect the AF CON and DATA CON 3.5mm sockets to your computer's sound card (or an external USB sound card). The provided 3.5mm stereo plugs can be used to create custom cables if needed, connecting the audio input/output and data lines to your sound card's microphone and speaker jacks.

Note:

The CE-19 does not include an integrated sound card. An external USB sound adapter or a computer with dedicated speaker and microphone jacks is required for digital mode operation.
Refer to your transceiver's manual and digital mode software documentation for specific sound card settings and configuration.

4. Operating Instructions

The Xiegu CE-19 acts as an interface, facilitating communication between your Xiegu transceiver, an amplifier, and a computer. Its operation is largely dependent on the configuration of the connected devices and software.

4.1. Digital Mode Operation

Ensure the CE-19 is correctly connected to your transceiver and computer's sound card as described in Section 3.
Install and configure your preferred digital mode software (e.g., WSJT-X, FLDIGI) on your computer.
Within the software, select the appropriate sound card input/output devices corresponding to the CE-19 connections.
Configure the PTT control. The CE-19 provides PTT signaling from the transceiver's ACC port, which can be used by the digital mode software or amplifier.
Adjust audio levels on both the transceiver and computer to achieve optimal signal-to-noise ratio and prevent overdriving.

4.2. Amplifier Control

When connected to an XPA125B amplifier, the CE-19 relays PTT and band data signals from your transceiver to the amplifier, enabling automatic band switching and transmit/receive control. Consult the XPA125B manual for specific amplifier settings.

5. Maintenance

The Xiegu CE-19 is a low-maintenance device. Follow these guidelines to ensure its longevity:

Keep the device clean and free from dust. Use a soft, dry cloth for cleaning.
Avoid exposing the device to extreme temperatures, humidity, or direct sunlight.
Ensure all cable connections are secure to prevent intermittent operation.
Do not attempt to open the enclosure or modify the internal circuitry, as this will void the warranty and may damage the device.

6. Troubleshooting

If you encounter issues with your CE-19, consider the following troubleshooting steps:

Problem	Possible Cause / Solution
No audio or data signal to/from computer.	Verify all 3.5mm audio/data cables are securely connected to the CE-19 and the computer's sound card. Ensure the correct sound card input/output devices are selected in your computer's operating system and digital mode software. Check audio levels on both the transceiver and computer. Confirm the 8-pin ACC cable is properly connected between the transceiver and the CE-19.
PTT not activating amplifier or transceiver.	Check the PTT CON 3.5mm connection. Ensure the 6-pin Mini-DIN cable to the XPA125B is correctly connected. Verify PTT settings in your digital mode software or transceiver.
Device not recognized by computer (if applicable).	The CE-19 is a passive interface; it does not require drivers. Ensure your sound card or other connected peripherals are correctly installed.
Difficulty with cable assembly.	The CE-19 includes 3.5mm stereo plugs for custom cable creation. Refer to online resources or amateur radio forums for detailed wiring diagrams specific to your transceiver and sound card setup.
