2.1 Tune up procedure
Firstly，please equip the module and accessories as the figure 4.
M10_User_Guide_V1.00 -5-

Then ,switching the H switch to ON state, J switch to ON state；Press the Fbutton PWRKEY for about
2 second, then the LED glint，and the module is tuningup successfully；( the location of All Switches and
buttons please see the Figure 1)
2.2 Serial interfaces
The module provides two unbalanced asynchronous serial ports. One is the serial port ,the other is the
debug port. The module is designed as a DCE (Data Communication Equipment), following the traditional
DCE-DTE (Data Terminal Equipment) connection. The module and the client (DTE) are connected
through the following signal (as following figure shows). Autobauding supports baud rate from 4800bps to
115200bps.

2.3 Antenna interface
The Pin 43 is the RF antenna pad. The RF interface has an impedance of 50Ω.
2.3.1 Antenna installation
M10 provides an RF antenna PAD for customer’s antenna installation. The customer’s antenna should be
located in the customer’s main board and connect to module’s antenna pad through microstrip line or other
type RF trace which the impendence must be controlled in 50Ω. To help the customer to ground the
antenna, M10 comes with 2 grounding pads located close to the antenna pad.

Name Pin Function
RF_ANT 43 RF antenna pad
GND 42
GND 44
If the customer installs the antenna via a soldered microwave coaxial cable, we would suggest the customer
to choose RF cable carefully so as to minimize the loss on the RF cable. And the recommended insertion
loss should try to meet the following requirements:
zGSM850/EGSM900<0.5dB
zDCS1800/PCS1900<1dB

PCS1900 1930 ～1990MHz 1850 ～1910MHz 512 ～810
2.3.5 Recommended impedance matching circuit
The impedance of M10’s RF_ANT port is 50Ω. If the impedance of antenna is close to 50Ωin all working
frequency bands, the antenna could be connected to the RF_ANT port directly via 50Ωtransmission line.
But if the impedance of antenna is not close to 50Ω, a T-type or π-type matching circuit should be inserted
between transmission line and antenna. The matching components should be placed as close as possible to
the antenna’s feed point.
The following 2 figures show the reference designs of T-type and π-type matching circuits.
