Extension slots and ports
Built-in 2 GHz wireless access point module, AP/station/bridge/p2p modes are supported. Onboard PIF
antennas built in. Antenna gain1.5 dBi.
miniPCIe slot and two SIM slots (can’t be used without a modem installed, can’t be used both at the
same time) to be used with a 3G/4G/LTE modem. Onboard antennas available, but openings for
external antennas are provided on the case.
Built-in GPS module with a built in antenna. One uFL connector provided for an optional external
antenna. To enable, set the port to serial0 (this disables the DB9 port on the unit).
One 10/100 Ethernet port, supporting automatic cross/straight cable correction (Auto MDI/X). Either
straight or crossover cable can be used for connecting to other network devices. The Ethernet port
accepts 12-57 V DC powering from a passive PoE injector.
One DB9 RS232 serial port for serial console access. Configured as 115200 bit/s, 8 data bits, 1 stop bit,
no parity. Can’t be used if built-in GPS is enabled on serial0.
One microUSB 2.0 port for powering only.
Configuration
RouterOS includes many configuration options in addition to what is described in this document. We suggest to
start here to get yourself accustomed to the possibilities: http://mt.lv/help. In case IP connection is not available, the
Winbox tool (http://mt.lv/winbox) can be used to connect to the MAC address of the device from the LAN side (all
access is blocked from the internet port by default).
For recovery purposes, it is possible boot the device from network, see section Buttons and jumpers.
miniPCIe slot
The device is equipped with a miniPCIe slot to be used with a 3G/4G/LTE modem. Two SIM slots are provided for
use together with a miniPCIe modem. SIM slot is not usable separately.
In this case, an internal antenna is connected to the LTE installed card (located inside the enclosure).
Optional, replacing a miniPCIe module should be done by a qualified person, please follow safety precautions
when handling electrical equipment:
1. use a wrist grounding strap when unpacking and working with electrical components to avoid electrical
discharge (ESD) damage,
2. open front cover by unscrewing one screw with Philips PH2 screwdriver,
See mikrotik.com/products for the latest version of this document. Document #49792 Modified on: 05.JUN.2019
3. remove four screws on the bottom of the case and lift off the top part of the case. You will see the antenna
attached to it,
4. locate the miniPCIe slot on the PCB and remove two factory attached screws,
5. attach provided a thick thermal pad to the card, and install the card into miniPCIe slot so that thermal pad is
between PCB and card,
6. secure card in place using previously removed two screws,
7. attach the grey uFL connector to the MAIN antenna connector of the modem, attach the black cable to the
secondary (or AUX) connector,
8. it is possible to use external antennas, to attach antenna connector use 6.5 mm drill bit to drill holes on the
side of the unit,
9. please see picture bellow on how to place rubber seals for best water protection,
10. attach antenna connectors to the installed card and GPS, as additional rubber silicone can be used to
secure connectors in place on card and PCB board,
11. attach a thinner thermal pad to the top of the card,
12. reassembly in back order.
After you have reinserted the device into the case and secured it with the screws that were removed earlier, slide in
the SIM cards from your mobile operator into the SIM slots, with the chips facing as shown on the port label. The
