Installation / startup

Incorrect characters on screen

• Duplicate characters on screen

Cause:

Your communication program is set to half-duplex or echo.

Remedy:

Enter ATE0 to deactivate command echo in command mode or

 

deactivate the echo in the communication program.

• Only the characters from the distant station are incorrect

Cause:

The GSM module’s data format does not match that of the distant sta-

 

tion.

Remedy:

Set the parameters in your communication program accordingly (data

 

bits, parity, stop bits to 8, N, 1).

GSM module does not dial

Cause:

A cable has been disconnected.

Remedy:

Make sure that all cables are securely connected. Tighten all connecting

 

screws.

Cause:

The GSM network does not or does not yet support the fax/data

 

modes. The GSM module returns NO CARRIER.

Remedy:

Ask your network operator when these modes will be supported in

 

your network.

Cause:

The GSM module has activated barred dialing.

Remedy:

Switch the GSM module off and then on.

Cannot receive fax

Cause:

Some fax programs that support TR-29.2 Class 2 expect the bits of the

 

fax code to arrive in an order different from the one defined in the

 

SP2388 specification. If the GSM module transmits the fax data bits to

 

the computer in the wrong order, the fax program cannot receive whole

 

fax pages. For this reason, the GSM module has been equipped with

 

the AT+FOPT=n command.

Remedy:

Enter one of the following two commands and then check whether the

 

system is functioning correctly: AT+FOPT=1,0 (bit order as specified in

 

TR-29.2 Class 2, Draft SP2388); AT+FOPT=1,1 (opposite bit order, fac-

 

tory configuration for all countries).

Cause:

The GSM network does not yet support the fax/data modes. The GSM

 

module returns NO CARRIER.

Remedy:

Ask your network operator when these services will be supported in

 

your network.

Cause:

Your network operator has not released your SIM card for the fax/data

 

modes.

Remedy:

Ask your network/service operator to release these features.

M1 specifications

The Siemens M1 is a prominent urban transit solution designed for efficient and sustainable public transportation systems. This innovative metro train has become a staple in various metropolitan areas, known for its balance of performance, safety, and passenger comfort.

One of the key features of the Siemens M1 is its modular design, which allows for flexibility in configuration depending on specific transit needs. The train typically consists of multiple carriages that can be adjusted for length and capacity, accommodating different passenger volumes while minimizing operational costs. This adaptability makes the M1 ideal for growing urban environments where ridership numbers can fluctuate.

The Siemens M1 is built with advanced technologies that enhance its operational efficiency. It utilizes a lightweight construction, primarily through the use of aluminum, which reduces energy consumption while still maintaining structural integrity and safety standards. The train is also equipped with cutting-edge traction systems that ensure smooth acceleration and fast braking, resulting in a comfortable ride for passengers.

Safety is a paramount concern in transit systems, and the M1 incorporates various safety technologies. It features advanced signaling systems that enhance communication between trains and trackside equipment. Moreover, the train is designed with anti-collision measures and real-time monitoring systems that can detect faults before they lead to service disruptions.

Passenger comfort is another critical aspect of the Siemens M1 design. The interiors are spacious and feature modern seating arrangements, allowing for easy movement within the train. Large windows provide natural light and views of the outside environment, contributing to a more pleasant travel experience. The train also offers features like climate control, information displays, and accessibility options for passengers with reduced mobility.

Environmental sustainability is an integral part of the Siemens M1’s design. It is tailored to reduce carbon emissions, featuring energy-efficient systems that lower the overall ecological footprint. Additionally, the train can be integrated with renewable energy sources, further promoting green public transport initiatives.

Overall, the Siemens M1 stands out as a versatile and efficient urban transit option, combining modern technology and design principles that cater to the needs of both operators and passengers. With its focus on safety, comfort, and sustainability, the Siemens M1 continues to play a vital role in shaping the future of urban mobility.
