AT Command Set

8.37 AT^SSYNC Configure SYNC Pin

The ^SSYNC command serves to configure the SYNC pin in the ZIF connector of the GSM engine. Please note that the pin may be assigned different functions, depending on the design of the host application. MC35 Terminal supports only <mode>=1.

For detailed information on the SYNC pin of the MC35 module refer to [1]. Before changing the mode of the SYNC pin, carefully read the technical specifications.

Parameter

<mode> 0 MC35 module: Enables the SYNC pin to indicate growing power consumption during a transmit burst. You can make use of the sig- nal generated by the SYNC pin, if power consumption is your con- cern. To do so, ensure that your application is capable of process- ing the signal. Your platform design must be such that the incoming signal causes other components to draw less current. In short, this allows your application to accomodate current drain and thus, sup- ply sufficient current to the GSM engine if required.

MC35 Terminal: not applicable (do not select mode 0).

1Enables the SYNC pin to control a status LED. On the MC35 Ter- minal, this is the LED placed on the front panel. If you use the MC35 module, the SYNC pin can control an LED installed in your application.

The LED functions described Table 10 are applicable both to the module and the terminal.

Note: Mode 1 is the default mode for the MC35 Terminal.

The SYNC pin mode is stored to the non-volatile Flash memory, and thus retained after Power Down.

MC35 specifications

The Siemens MC35 is a compact and versatile modem designed primarily for mobile communication, data transmission, and machine-to-machine (M2M) applications. Launched in the early 2000s, it quickly became popular due to its blend of performance, reliability, and ease of integration, making it a solid choice for developers and businesses.

One of the key features of the MC35 is its support for GSM and GPRS technologies. This allows it to connect seamlessly to various networks, enabling users to transmit data at speeds that were impressive for its time. The GPRS capability can offer data rates of up to 171.2 kbps, allowing for efficient data transfer even in areas with limited connectivity.

The MC35 is designed to support both SMS and voice functionalities, making it adaptable for a range of applications. This includes remote monitoring, telemetry, and alarm signaling. The ability to send and receive SMS messages is a significant advantage for applications that require immediate alerts and notifications, enhancing its utility in security systems and industrial automation.

Furthermore, the modem is equipped with a range of interfaces, including serial communication (RS232), which makes it compatible with various hardware devices. This facilitates easy integration into existing systems, whether for industrial machinery or consumer electronics. Additionally, it features a robust software development kit (SDK), which enables developers to create custom applications tailored to their specific requirements.

Power consumption is another notable characteristic of the Siemens MC35. It is engineered to be energy-efficient, which is especially important for battery-operated devices or systems that require a prolonged operation without frequent recharging or maintenance.

In terms of physical characteristics, the MC35 is compact and lightweight, allowing it to fit into various enclosure designs without occupying much space. Its durability ensures it can perform reliably in different environments, making it suitable for outdoor and industrial applications.

To summarize, the Siemens MC35 stands out as a reliable modem with a rich feature set that includes GSM and GPRS support, SMS and voice capabilities, easy integration through various interface options, and energy-efficient operation. Its adaptability makes it a valuable tool for a wide array of communication and data transmission tasks, solidifying its place in the evolution of mobile communications technology.
