(see chapter 0 of the manual to access the LUMA X webpage). If your modem firmware is outdated, please contact Hydromea in order to get the latest version of the LUMA X firmware. 2 Initial setup Note: while submerging the LUMA X, a small number of bubbles may come out of the pressure compensation vent at the connector end of the modem. -

Figure 1: Typical initial test setup. The IP addresses of the modems are not critical but useful to differentiate them 2.1 Windows 10 setup The following steps explain how to set an IP address on your Windows 10/11 PC go to → Settings → Network & Internet → Ethernet (in left column) → Network and Sharing Center (in right column) →... -
Page 6: Luma X Setup
Connect only one LUMA X to a computer via an Ethernet connection using Hydromea’s power/data cable. Connect the LUMA X to a suitable supply voltage (12 V – 36 V) using Hydromea’s power/data cable. Optional step: to test that the IP address has been set correctly, the computer should now be able to ping the LUMA X on its default IP address 192.168.102.101 and the... -
Page 7: Setting The Ip Address
All LUMA X have their IP address factory-set to 192.168.102.101. You can change the IP address of the modem through the web interface. 2.3 Setting the IP address For the initial test, modem (1) can remain at the default IP address. The other modem (2) must be set to a new IP address that is unique within the subnet. -
Page 8: Testing The Communication
Click “Set”. The new IP address is now temporarily applied, and the page will reload showing the new IP address: To store the new setting to flash memory, click “Save”. The modem is now set to the new IP address. 2.4 Testing the communication To test communication by exchanging messages between modems, the modem’s firmware provides a simple interface as shown in Figure 4. -

The optical link is now ready and will forward any ethernet traffic from one side to the other side. -
Page 10: Main Page
3.1 Main page Figure 5: main page of the web-based configuration-UI This page provides information about the current revision of the hardware, firmware and API. It also provides the firmware’s SHA and the unique processor ID. 3.2 Parameters page Figure 6: parameter page of the web-based configuration-UI LUMA X 9/2023... - Page 11 This is the main configuration page for the LUMA X. Hovering over the “?” next to each parameter provides a short description. Note: No change will become effective until the “Set” button has been pressed. After power- cycling the modem, the parameters will revert to the previous setting. Pressing the “Save” button will store the new set of parameters into the modem’s flash memory and make it the new permanent set of parameters.
- Page 12 Auto-speed On: the modems automatically negotiate the optical speed at active which they should communicate. If the modems are close to each other or there is a lot of ambient light variation, the modems may switch their speed often and it can vary between 1Mbits/s and 10Mbits/s, which can be undesirable.
- Page 13 if Auto gain control is On, the current gain value is displayed, but cannot be changed. if Auto gain control is Off, it is a mutable parameter Receiver In case the Auto gain control is Off or On - with fixed sensitivity sensitivity, this is a mutable parameter.

Page 14: Status Page
3.3 Status page Figure 7: status page of the web-based configuration-UI This page provides information about the current status of the LUMA modem and is updated once every second. For all data rates (throughput, packet CRC errors, received and loss), three values are displayed: per second, per minute and total since the start of the modem. - Page 15 Number receivers the number of receivers the modem is using (the sensitivity) to active detect light pulses (1 .. 4) LUMA voltage supply voltage of the modem LUMA voltage minimum value of the supply voltage observed over the last minute.

The current IP address of the of the web-based configuration interface is displayed and can be changed. -
Page 17: Modem Firmware Upgrade Using Lumaconf
Start LumaConf Ensure that the LUMA X is connected to a computer through the serial connection. This is most easily achieved by using Hydromea’s power/data cable-box which provides a serial connection through a USB-to-serial conversion within the power/data cable and can be accessed via a micro-USB port. - Page 18 Note: please make sure that you select the proper firmware image, the last digits of the filename LX########## need to match the serial number engraved on the modem. o Factory reset only: clicking on Clear Settings will factory reset all LUMA X settings.

SubConn's instructions. 6 API Hydromea provides an API, based on REST, with which key operating parameters of the LUMA X can be changed or status parameters retrieved while the modem is running. The following tables provide a complete list of these parameters, followed by examples showing how to retrieve and change them (in case they are writable). - Page 20 crc_errors_sec Number of CRC errors that happened in the last second in the Luma. A high number could indicate some noise or that the Luma is at the edge of the maximal range pkt_recv_sec Number of packet received in the last second pkt_loss_sec Number of packet lost in the last second.
- Page 21 nb_additional_rcv Number of extra receivers active status_electronics Status of the electronics, 0 indicates an internal problem volt_board The voltage the LUMA sees at its VCC input port. volt_board_min The voltage the LUMA sees at its VCC input port, sampled at a higher rate and displaying the minimum value observed over the last minute.
