Antenna connectors SMA

Fig. 4.2: Antenna connectors SMA

MG102i uses SMA antenna connectors:

  • Mob 1, Mob 2 for GSM/UMTS/LTE antenna connection (Mob 1 for 1st UMTS module, Mob 2 for LTE as auxiliary second connector or for 2nd UMTS),

  • GPS for GPS active or passive antenna,

  • WLAN 1 and WLAN 2 for WiFi Antenna (WLAN 2 as auxiliary).

Nde  – No damage expected

[1] – If the applied voltage is > 15 V, damage is likely
[2] – If the relay is closed (normally open), the relay is damaged when current > 5 A
[3] – If the relay is closed (normally closed), the relay is damaged when current > 5 A
[4] – If the applied voltage is > 40 V, input circuit damage is likely

4.2.5. Reset button

Reset button

Fig. 4.6: Reset button

The Reset button is placed close to the SIM holders and it is labeled “Reset”. Use a blunt tool with 1 mm in diameter (e.g. paper clip) to press the button.

Keep it pressed for at least 3 seconds for reboot and at least 10 seconds for a factory reset. The start of the factory reset is confirmed by all LEDs lighting up for one second. The button can be released afterwards.

[Note]Note

If the button is being pressed at least 15 seconds until all LED diodes blink red, the recovery procedure is started. The recovery image can be provided on demand and a special procedure utilizing the TFTP transfer from your computer is required. Contact our technical support team for more details.
