Inserting the SIM card
Insert your SIM card as shown in the figure below until it locks into place.
Power supply
The MC92 is operated with a supply voltage of 8 - 30V DC. Please connect an external DC power
supply with an output voltage of 8 - 30V DC to the power supply socket "PWR".
Please connect the power supply unit to the power supply or switch on the power supply. A green
"PWR" LED will light up.
After a short initialization phase (approx. 30 seconds) the device is ready for operation.
Configuration via Putty
1. In Putty, “Serial” as a Connection type.
2. Choose the right Serial port for your USB-RS232 connector.
3. Set the speed to "115200".
4. Expand the connection tab on the right side, then under “SSH” click on “Serial”.
5. Set "Flow control" to "None"
Configuration via STTY
You can use "stty" to configure your “tty” and connect to the Modem using "cat" and "echo".
1. Using Command Prompt, give the command:
stty -F /dev/ttyUSB0 -crtscts 115200 cs8 -cstopb -parenb -echo –echon1
Execute cat /dev/ttyUSB0 in one terminal and echo "AT+CSQ" >/dev/ttyUSB0 in
another.

1Using Command Prompt, give the command:
minicom --device /dev/ttyUSB0 --baud 115200,8,N,1
2Disable flow control by pressing CTRL+A followed by O to get into configuration. Then go
down to "Serial port setup", press "Enter" to enter and press "F" do toggle "Hardware
Flow Control"
The Modem will now respond to AT-Commands.

AT Commands
AT commands for SIM presence and status
8.1.1 SIM Presence
1. Enable the extended error codes to get a verbose format:
AT+CMEE=2
OK
2. Now get the status of SIM presence:
AT+cpin?
+CME ERROR: SIM not inserted
Above AT command response indicates that SIM card is not present.
3. Verify that SIM is inserted properly and check again:
AT+cpin?
+CPIN: READY
OK
When the SIM card is ready, above AT response will be received from the module.
8.1.2 SIM PIN Status
1. Get the status of SIM PIN:
AT+CPIN?
Pin status can be:
READY: SIM PIN is already unlocked or lock has been disabled.
SIM PIN: This means SIM PIN is locked and code is required.
SIM PUK: Maximum number to retries to unlock has reached. PUK code is required from
network provider
2. If SIM PIN is required enter the following command to unlock the SIM:
AT+CPIN=”XXXX”
Enter the SIM PIN instead of XXXX

Send SMS using AT commands
8.2.1 Setting up the device
Activate SMS text mode using the following command:
AT+CMGF=1
In text mode there are some additional parameters that can be set. Using the following
command, we can read the current values:
AT+CSMP?
The device will respond with a string like this:
> +CSMP: 1,169,0,0
> OK
The first value is a combination of some option bits:
bit 7
RP
Reply path, not used in text mode
bit 6
UDHI
User Data Header Information
bit 5
SRR
Set this bit to request a delivery report
bit 3,4
VPF
Validity Period, set b4=1 if a VP value is present
bit 2
RD
Reject Duplicates, do not return a message ID when a message
with the same destination and ID is still pending
bit 0,1
MTI
Message Type Indicatorb1=0 & b0=0 -> SMS-DELIVERb1=0 &
b0=1 -> SMS-SUBMIT

LTE Data-Gateway/Terminal
MC Technologies GmbH, Kabelkamp 2, 30179 Hannover, Germany
Tel: [phone], Fax: [phone], Website & Shop: www.mc-technologies.net, Email: [email protected]
15
Bit 0 of the message is always set when sending messages (SMS-SUBMIT). So, the first value should
be 1 or higher. The second parameter sets the Validity Period of the message. This value is encoded
as follows:
0 - 143
(VP + 1) x 5 minutes
144 - 167
12 Hours + ((VP-143) x 30 minutes)
168 - 196
(VP-166) x 1 day
197 - 255
(VP-192) x 1 week
The third parameter contains the PID (Protocol Identifier). This parameter is only used for advanced
messaging. The fourth parameter contains the DCS (Data Coding Scheme). This parameter is used to
select the character set/message type. When setting the DCS parameter to '0' standard 7-bit text is
sent. When setting this parameter to '16' the message is sent as a flash message.
To send a message with a validity period of 1 day, the parameters have to be set like this:
Bit 0 and 4 of the first field has to be set, so the first value will become 1 + 16 = 17.
Send the following command to the modem to set these parameters:
AT+CSMP=17,167,0,16
If the modem responds with "OK", the modem is ready to send (flash) text messages with a validity
period of 1 day.
8.2.2 Sending the message
To send the SMS message
AT+CMGS="[phone]"
Replace the above phone number with the wanted phone number. The device will respond
with:
>
Type the message text and send the message using the <CTRL>-<Z> key combination:
> Test! <CTRL-Z>
<wait>
> +CMGS: 62 Message was sent correctly

8.2.3 Sending a Unicode SMS message
To check whether your device supports this mode, just type the following command:
AT+CSCS=?
This command displays the code pages supported by the device. The device will respond like this:
+CSCS: ("IRA","GSM","UCS2")
If this string contains "HEX" or "UCS2", Unicode seems to be supported. To specify that you will use
a UCS2 string to send the message, set the codepage to "UCS2" depending on the device response.
In our example we will set the device to "UCS2":
AT+CSCS="UCS2"
Next, specify the correct DCS (Data Coding Scheme) for Unicode messages, which is 0x08. Set this
value by changing the fourth parameter of the AT+CSMP command to '8':
AT+CSMP=1,167,0,8
The device is now ready to send messages as Unicode.
GPS
8.3.1 Turn on and off the GNSS
Turn on GNSS function:
AT+QGPS=1
Turn off GNSS function:
