GL-ATX Board User Guide

The ATX board is an optional accessory for GL.iNet KVM device. As a smart power management module, it enables remote control of the controlled device's power supply by simulating physical power button operations (power on/off/reboot).

The ATX board will be installed in the controlled device's chassis, providing more concealed and stable power management.

Components

There are some components in the ATX Package:

• ATX main board
• USB-A to Type-C cable
• A 9-PIN Wire Set
• Screw package
• ATX Bracket Set

ATX Board PIN-OUT

Explanation of Interfaces:

1. Type-C Interface: Connect to the KVM device.
2. Firmware Upgrade button: for the single-chip microcomputer on the ATX main board.
3. Reset button.
4. Connect to the control line of the computer panel.
5. Connect to the F_PANEL interface of the computer.

Note

Interfaces 4 and 5 can be connected interchangeably. That is, interface 5 can be connected to the control line of the computer panel, and interface 4 can be connected to the F_PANEL. The LED status on the board is consistent with the Power LED status on the computer panel.

ATX Board Installation

Watch this video to install ATX board, or follow the steps below.

1. Screw ATX Board and Bracket

Fix the ATX board and the ATX Bracket Set with the screws provided.

2. Install ATX Board into the Chassis

Connect interfaces 4 and 5 respectively to the controlled computer's control line and F_PANEL interface.

The 9-PIN Wire Set provided in the ATX Package allows you to connect one of the ATX board interface 4/5 to the controlled computer's control line or F_PANEL interface.

You need to use the wire set included in your computer chassis to connect another ATX board interface 4/5 to the controlled computer's control line or F_PANEL interface.

Note

The interface polarity may vary depending on different PC chassis. Please double check it before installation.

Here are some examples of connecting one of the ATX board interfaces 4/5 to the controlled computer's F_PANEL interface.

Example 1. For 10-1 pin PANEL

If the row of pins on your controlled computer's motherboard used to connect to the control panel is a 10-1 pin PANEL, as shown below.

Please refer to the diagram below for connection, make sure that the silkscreen printing (i.e., the words HDDLED±, RESET SW, POWER SW, POWERLED+, etc.) is visible facing outward and not obscured facing inward.

Then use the wire set included in your computer chassis to connect another ATX board interface to the computer control line.

Example 2. For 20-5 pin PANEL

If the row of pins on your controlled computer's motherboard used to connect to the control panel is a 20-5 pin PANEL, as shown below.

Please refer to the diagram below for connection, make sure that the silkscreen printing (i.e., the words HDDLED±, RESET SW, POWER SW, POWERLED+, etc.) is visible facing outward and not obscured facing inward.

Then use the wire set included in your computer chassis to connect another ATX board interface to the computer control line.

Example 3. For 20-8 pin PANEL

If the row of pins on your controlled computer's motherboard used to connect to the control panel is a 20-8 pin PANEL, as shown below.

Please refer to the diagram below for connection, make sure that the silkscreen printing (i.e., the words HDDLED±, RESET SW, POWER SW, POWERLED+, etc.) is visible facing outward and not obscured facing inward.

Then use the wire set included in your computer chassis to connect another ATX board interface to the computer control line.

The final connected ATX board is shown below.

Then place the ATX board bracket on the side frame of the computer chassis (if required).

3. Connect ATX Board and KVM

Connect the Type-C interface of ATX board to the USB-A interface of the KVM device (such as Comet GL-RM1), using the included USB-A to Type-C cable.

This completes the installation of the ATX board.

Now you can log in to the Comet, navigate to Accessories to set the ATX power.

Troubleshooting

After installing the ATX board, if you cannot control the remote device's power (on/off) via the KVM, here are some suggestions:

• Ensure the controlled device can be powered on/off normally when the physical power button on the main chassis front panel is pressed.

• Check the wiring polarity. Try flipping the connector polarity on the controlled device's motherboard to avoid incorrect wiring.

• When connecting to the F_PANEL interface on the controlled device's motherboard, ensure the silkscreen printing (e.g., HDDLED±, RESET SW, POWER SW, POWERLED+, etc.) is visible facing outward, not obscured facing inward.

• Upgrade the KVM's firmware.
