Safety Precautions
M110 Series Cellular Modem User Guide 5
1. Safety Precautions
1.1 General precautions
The modem generates radio frequency (RF) power. When using the modem,
precaution must be taken to ensure safety as well as compliance with all
regulations that surround the use of RF equipment.
Do not use the modem in aircraft, hospitals, and petrol stations or in places where
using mobile cellular products or other RF equipment is prohibited, and make sure
that the modem will not be interfering with nearby equipment such as pacemakers
or medical equipment.
The antenna of the modem should be directed away from computers, office
equipment, home appliance, etc., and always keep the modem at a minimally safe
distance of 26.6cm or more from a human body.
Do not put the antenna inside metallic boxes or other containers.
1.2 Using the modem in vehicles
Check for any regulations or laws authorising the use of GSM, W-CDMA, and LTE
equipment in vehicles in the country before installing the modem.
Installation of the modem should be done by qualified personnel. Consult your
vehicle dealer for any possible interference concerns related to the use of the
modem.
Power consumption of the modem and related circuit should be taken into
consideration when the modem is powered by the battery of the vehicle as the
battery may deplete after an extended period.
1.3 Protecting your modem
To ensure error-free usage, please install and operate the modem with care and comply
with the following.
Do not expose the modem in extreme conditions such as high humidity/rain, high
temperatures, direct sunlight, caustic/harsh chemicals, dust, or water.
Do not try to disassemble or modify the modem as there is no user serviceable
parts inside and warranty will void in case of tampering.
Do not drop, hit, shake the modem or place in extreme vibration.
Do not pull the power supply cable. Attach or detach it by holding the connector
after switching off the supply.

Safety Precautions
M110 Series Cellular Modem User Guide 6
Install and connect the modem in accordance with this user manual. Failure to do
so will void the warranty.

6. Hardware Installation
6.1 Inserting SIM card:
(1) Eject the SIM tray by pushing the eject button inwards.
(2) Pull the SIM tray out.
Place the mini-SIM card on the tray with SIM chip facing up, then push the tray
back in place carefully.
6.2 Connecting cellular antenna:
Screw (clockwise) the SMA antenna onto the SMA connector.

Hardware Installation
M110 Series Cellular Modem User Guide 14
6.3 Connecting USB Type-C cable
6.4 Connecting RS-232 DB-9 serial cable
Connect the RS-232 DB-9 serial cable and secure the connection by tightening
both thumb knobs on the connector.
6.5 Powering the modem
Connect the 4-pin Micro-Fit connector power supply to the modem as shown
above.

Communication with the Modem
M110 Series Cellular Modem User Guide 15
7. Communication with the Modem
After all the above setup, communications between the terminal equipment and the
modem can now be tested, AT commands can be sent to the modem using a terminal
program (i.e., Tera Term) installed on computer for configuring the modem.
7.1 Communications test
•Connection between the terminal equipment and the modem
can be made using two types of cables:
RS-232 DB-9 Serial cable
or
USB Type-C cable
•Configuration of the RS-232 port on the terminal
equipment/program should initially be:
Baud-rate: 115,200 bps
Data bits: 8
Parity: None
Stop Bits: 1
Flow control: None
•To see if the communications between the terminal program
and the modem is established, enter:
AT
and modem will respond with:
OK
7.2 Echo Function
The default echo setting is off/disabled (ATE0), to enable the echo function,
either:
•Enable “Local echo’ in terminal program
or
•Enable the modem echo function (enter ATE1)
In M2M application, it is highly recommended to disable the modem echo function
(enter ATE0) to avoid unnecessary traffic between DTE and DCE.

Communication with the Modem
M110 Series Cellular Modem User Guide 16
In terminal program, if response is not displayed after an AT command is entered,
recheck the above setting.
If communications cannot be established with the modem, check:
•The RS-232 physical connection
•The RS-232 configuration
After communication is established, refer to below AT commands to start using the
modem.
AT Command
Description
AT+CGMI
To check the module manufacturer identification
AT+CPIN=XXXX
To enter a PIN code (if required) (XXXX is actual PIN)
AT+CSQ
To verify the received signal strength
AT+CREG?
To verify the network registration status
ATD<phone number>;
To initiate a voice call
ATH
To end the above voice call
7.3 Received Signal Strength
The modem can only establish a call or data session when the received signal
strength is sufficient. In terminal window, enter AT+CSQ to see the received signal
strength, then the modem will respond in the following format:
+CSQ: <RSSI>,<BER>
or
<RSSI>,<BEP>
or
<RSSI>,<ECN0>
or
<RSSI>,<RSRQ>
Where:
<RSSI> : Received Signal Strength Indication
<BER> : channel Bit Error Rate (GPRS)
<BEP> : channel Bit Error Pattern (EGPRS)
<ECN0>: Energy per Chip Noise ratio (UMTS)
<RSRQ> : Reference Signal Received Quality (LTE)
For SMS, voice, and data operation, please refer to the below table for sufficient
RSSI levels.

7.4 Network Registration
To verify network registration, first ensure the SIM card has been provisioned.
If the model has embedded SIM, first ensure the modem has been activated by
the network provider.
To see the network registration status, in terminal program, enter:
AT+CREG?
and refer to the below responses of network registration status.

If it is not registered on the network, check the following.
•If the antenna was attached properly
•The received signal strength (refer to section 8.2)
•If the SIM card was provisioned
7.5 PIN Code
To verify, in terminal program, enter:
AT+CPIN?
and refer to the below responses of PIN code status:
Response
