Page 4: Introduction
For the purpose of initial setup and testing, the default network configuration and IP addresses are used, as shown in Figure 1. For operational use, the IP addresses of the LUMA X modem and the computers connected to them can be configured differently to suit individual network requirements. -

On the remote PC, repeat the procedure, but set the IP address to 192.168.102.103. 2.1.2 LUMA X setup Once the host computer’s IP address is set correctly the connection to the LUMA X can be tested. Connect only one LUMA X to a computer via an Ethernet connection using Hydromea’s power/data cable. -
Page 7: Setting The Ip Address
The LUMA X web interface main page should appear (see Figure 4) All LUMA X are factory-set to boot-up into config mode and their factory-set IP address is 192.168.102.101. In order to use several LUMA X within the same network for configuration and testing, they need to be set to differing IP addresses. -
Page 8: Setting Modems To Active Mode
The config mode is the inactive mode and the modem will not forward data between the ethernet cable and the optical interface. After setting the configuration, LUMA X can be switched to active mode. It will now behave as a bridge device, forwarding any traffic from the cable side via the optical link. This effectively connects the networks on both sides, comparable to a cabled connection between two switches or end devices. -
Page 9: Modem Configuration
This chapter will describe the modem configuration in detail. There are two ways to configure LUMA X, the built-in web interface as well as LumaConf, an external program. The web interface is the preferred way to configure LUMA X. LumaConf offers some additional test features that provide several performance metrics for a two-modem connection. -

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 LUMA X flash memory and make it the new permanent set of parameters.

(contact Hydromea for assistance if adjust required). Keep-alive When on, the modem will send short packets every 1-2 packets seconds, which helps to maintain optimal gain settings. When off, the modem will not emit any light unless there is data traffic, but there may be packet loss immediately after longer pauses in data flow until the gain control can adjust. -

Page 14: Modem Configuration And Testing Using Lumaconf
To use LumaConf, ensure that the LUMA X is connected to a computer via Ethernet and that it is powered up. After the start of LumaConf you will see the console shown in Figure 10. - Page 15 Note: If LumaConf cannot connect to the LUMA X, it will display “No LUMA connected”. Verify that your host PC is set to the IP address 192.168.102.100 (or respectively, the address specified as the “Host IP address” in the LUMA X parameters).

If multiple LUMA X are detected, their last IP address byte will be displayed in this drop-down list. The LUMA X which is to be configured can then be selected from this list.

Both LUMA X of a communication link need to be in active mode for normal operation. 4.1 LumaConf parameters Successfully setting a LUMA X into config mode makes the parameters in the lower half of the LumaConf main console changeable. Table 1 in chapter 3.1.2 provides an explanation of the parameters. -

For example, Figure 12 shows a LUMA X with the last byte of its Configuration IP address being 102 sending random data with high throughput which is received by LUMA X with the last byte of its Configuration IP address being 101 at 10 Mbps.

PDF graph of. The PDF graph will show the perceived throughput of the two LUMA X over a range of gain values. This can be useful to evaluate the autogain performance and, in case it has trouble to automatically find an optimal gain value, determine a value to which to set the gain manually in a controlled environment. -
Page 22: Api
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 23 Parameter Valid input Description start_state 0:config, 1:active The state which the LUMA X will boot into. This is factory set to config, but for normal operation this should be set to active optical_speed {1, 4, 6, 8, 10} Speed (in Mbits/s) of the optical Link. Note that higher transmit speeds mean less range.
