Siemens MC35 specification

AT Command Set

2.34 AT&D Set circuit Data Terminal Ready (DTR) function mode

Write command

AT&D[<value>]

Reference

V.25ter

Response

This command is only intended for data calls. The <value> parameter determines how the TA responds when circuit 108/2 (DTR) is changed from ON to OFF dur- ing data mode.

Parameter
<value>	0	TA ignores status on DTR.
	1	ON->OFF on DTR: Change to command mode while retaining
		the connected call.
	2	ON->OFF on DTR: Disconnect data call, change to command
		mode. During state DTR = OFF is auto-answer off.

Note

Line state refers to RS-232 levels.

2.35 AT&F Set all current parameters to manufacturer defaults

Execute command AT&F[value]

Reference

V.25ter

Response

TA sets all current parameters to the manufacturer defined profile.

Parameter
<value>	0	set all TA parameters to manufacturer default

Note

•List of parameters reset to manufacturer default (sorted by the associated AT commands):

E, Q, V, X, +CBST, +CRLP, +CRC, +CR, +CNMI, +CMEE, +CSMS, ^SCKS, ^SACM, +CREG, +CLIP, the S Parameters, &D, &C, &S, +CGDCONT, +CGQREQ, +CGQMIN

•In addition to the default profile, you can store an individual one with AT&W. To alternate between the two profiles enter either ATZ (loads user profile) or AT&F (restores factory profile). Refer to Chapter 2.38 for AT&W and Chapter 2.32 for ATZ.

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.
