Safety Precautions

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.

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.

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.

Install and connect the modem in accordance with this user manual. Failure to do so will void the warranty

Accessories

LED Status Indicator

The modem operation status is indicated by two LEDs, which are located on the front side described in the below table.

For further description on CSQ, refer to section 7.3 Received Signal Strength.

Hardware Installation

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

Connecting cellular antenna

Screw (clockwise) the SMA antenna onto the SMA connector

Connecting USB Type-C cable

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.

Powering the modem

Connect the 4-pin Micro-Fit connector power supply to the modem as shown above.

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.

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 was established, enter:
  AT
  and modem will respond with:
  OK

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.

In terminal program, if respond 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 the communications between both has been established, refer to below AT commands for start using the modem.

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>, <ECNO>
or
<RSSI>, <RSRQ>

Where:

<RSSI>    : Received Signal Strength Indication
<BER>    : channel Bit Error Rate (GPRS)
<BEP>    : channel Bit Error Pattern (EGPRS)
<ECNO> : Energy per Chip Noise ratio (UMTS)
<RSRQ> : Reference Signal Received Quality (LTE)

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

PIN Code

To verify, in terminal program, enter:
AT+CPIN?
and refer to the below responses of PIN code status.

Basic AT command summary

Below table is a summary of basic AT commands, for the full set of commands, refer to M110 Commands Guide.

*AT+CMEE=1 to enable +CME error result code, otherwise only ‘error’ will be displayed instead.

XXXX is the actual PIN code, if required.
