MTi User Manual
MTi to communicate via this alternative UART, use the command SetExtOutputMode (see [LLCP]). This
setting will be stored in the non-volatile memory, so the device will start up communicating over this
alternative UART, unless a USB connection is detected.
7.3.2.2 GNSS receiver
The MTi-G-710 needs an active antenna. The connection on the OEM board of the MTi-G-710 is done
with an u.FL miniature coax. See also

7.3.2.3 Connecting with the OEM board
Connecting to the OEM board is possible by using sockets with a pitch of 1.27 mm. Notable
manufacturers are Samtec, Molex and Hirose. Two examples of such sockets are:
Table 24: Part numbers for sockets that fit the headers on the MTi OEM

6-pins 1.27 mm pitch
Samtec
FFSD-04-01-N
Digikey: FFSD-04-01-N
Note that there is no Samtec connector (cable part) for a 6-pins receptacle. This means that you can
use an 8-pins or 10-pins header.
These connectors can be connected to ribbon cables without tools to make a cable like below. On the
right is an application of such a cable.
7.3.3 Additional interface specifications
The MTi has three IO lines on the main 10 pins connector (and thus on the 9-pins external Fischer
connector). These 3 lines can be configured individually for synchronization purposes (see section 6.2).
Make sure to always apply a common ground (see
us/articles/211592185-Synchronization-with-the-MTi
