| Q2. Why the device does not show the video only display <b><span class="tb_red">No Signals</span></b>?
| |
| </div>
| |
| <div class="mw-collapsible-content">
| |
| A:
| |
| * Please check the hardware connection. Double-check that the video capture device is connected correctly and tightly.
| |
| * Make sure you use the original HDMI port. If your desktop only has a VGA display port, there may be no video signal when you use VGA to HDMI adapter, and there is no way to solve this; However, you can try to lower the resolution and restart the PC to test, but the probability of success is very low.
| |
| * Change the HDMI cable to test.
| |
| * Test the X630 separately to check if there is HDMI output.
| |
| * Some laptops do not output any signal until you switch the output (usually via the FN + and an F5 key on the keyboard).
| |
| * Your computer maybe enter sleep mode, please exit sleep mode

| |
| rw
| |
| systemctl enable --now kvmd-oled
| |
| ro

| |
| Q6. Why OLED is not display?
| |
| </div>
| |
| <div class="mw-collapsible-content">
| |
| A: Please follow the steps below to check
| |
| | |
| 1. Please confirm that your OS is right:
| |
| | |
| Due to downloading the wrong firmware, the OLED cannot be displayed. We ALSO made such mistakes during testing.
| |
| | |
| [[File:Pi4-V3-HAT.png|800px]]
| |
| | |
| 2. Please check if the order of OLED screen pins is correct, please contact us if it's a wrong pin order;
| |
| | |
| [[File:OLED-IMG-4373-1.jpg]]
| |
| | |
| then runt the following command to check i2c address
| |
| sudo i2cdetect -y 1
| |
| <pre>
| |
| 0 1 2 3 4 5 6 7 8 9 a b c d e f
| |
| 00: -- -- -- -- -- -- -- --
| |
| 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
| |
| 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
| |
| 30: -- -- -- -- -- -- -- -- -- -- -- -- 3c -- -- --
| |
| 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
| |
| 50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
| |
| 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
| |
| 70: -- -- -- -- -- -- -- --
| |
| </pre>
| |
| | |
| '''3c''' is a hexadecimal number, it is the I2C address of OLED, if you can’t find this value, please shut down and reconnect X630-A3&OLED and run this command again, If you still can't find the OLED's I2C address, the OLED screen may be damaged.
| |
| | |
| '''PS''': The newest PiKVM V3 image does not include '''i2cdetect''' tool, and you can use the following command to check the i2c device
| |
| ls /sys/class/i2c-dev/i2c-1/devices/
| |
| 4. Then run the following command to enable OLED display:
| |
| rw
| |
| systemctl enable --now kvmd-oled
| |
| ro
| |

| |
| Q7. I want to control several pc power. Is it possible with one PiKVM-A3 and several x630-a5
| |
| </div>
| |
| <div class="mw-collapsible-content">
| |
| A. No, one kit can only control one pc, you can refer to [[X680]] to control up to 4 PCs.
