Recommended cables for use:
- length of cable connecting the switch and the LigoPTP device, <100m;
- use FTP cable outside;
- use shielded RJ45 plugs outside;
- it is recommended to solder the drain wire to the RJ45 plug;
- use UTP or FTP cable inside.
Proper grounding has to be ensured using the grounding stud found on the housing and the PoE inserter.
Multifunctional LED lights are installed in the device, which display the RSSI levels and help users to ensure the correct antenna alignment. Align both sides of the PTP link simultaneously.
The new model LEDs represent various device operations: boot-up, reset to default settings, reboot, firmware flashing, recovery mode in case of failure, and its primary operation—device status and signal levels.
Signal level indication
LEDs are used to indicate signal levels and their changes. The levels are represented using a combination of lights, colors, and brightness:  lighting up 1 through 6 LED lights,  lighting them up using three distinct colors—amber, yellow, and green, and  setting different LED brightness levels—low, middle, and high.
When the signal level changes from low to high, LED1 lights up in amber, starting with low brightness and shifting into high brightness. Afterwards, the brightness cycle repeats when the colors change to yellow and then to green. Once one LED reaches the green state, LED2 lights up in amber at low brightness and proceeds to green at high brightness.
Refer to the graph below for a visual example.
When the device is booting up, each LED represents a phase of the booting process. Starting with LED1, each LED turns on gradually until all of the 6 LEDs are on. Green LEDs signify a successful boot-up.
If any of the booting and startup phases fail, the LED representing that phase will light up in red. LED1–LED3 represent the bootloader, while LED4–LED6 represent kernel.
If all of the phases are successful, the LEDs turn off and perform their primary operation—signal level indication. If any of the phases fail, the LED remains turned on in that state until the problem is resolved.
Firmware Upgrade / Reboot / Reset to Default Settings
If a firmware upgrade, device reboot, or reset to defaults is being performed, blue LEDs light up and move in a snake pattern. The snake’s length is 6 LEDs. It moves from left to right and vice-versa every 100ms.
If the device enters the recovery mode (rare case), all of the LEDs begin blinking in red and yellow every 0.5 second.
Operation on GUI
The LEDs can be configured over the GUI:
- Always off: LED indications will be permanently disabled.
- Always on: LED indications will be permanently enabled.
- Auto off: LED indications will be disabled after a specified timeout.
The Antenna Alignment Tool measures the signal quality between the Master and Slave devices. To achieve the best results when aligning antennas, turn off all wireless networking devices within range of the device, except the device (or devices) with which you are trying to align the antenna. Watch the display for real-time feedback as you adjust the antenna.
Start/Stop – press to start or to stop antenna alignment.
Averaging – if enabled, the graph will display the average signal strength of both vertical and horizontal polarities.
Sound – if enabled, sound (beeps) will be produced during alignment (if the browser allows this).
Proper Antenna Alignment
1. Disable ATPC functionality.
2. Set the maximum Tx power.
3. Choose the compliance testing country code during installation.
Once alignment is completed, choose your country code and enable ATPC functionality.
