RS 232-Transparent-Mode (TransMode)

 

 

6.4.2TransMode Command

AT+T SEND="TransMode; ..."

AT+T SEND="TransMode; Enabled:Enabled;Password: Password; Format: Format;

Handshake:Handshake; Keep:timeout; Baudrate: RS232Speed;

Com:Port"

Switches the RS 232 to a connected device during dial-in from the outside so that the device can be controlled remotely.

Enabled

Sets theTransMode to active (On) or inactive (Off).

Password

Access password

 

This protects your Mitsubishi Super Modem AT from unauthorized dial-in

 

and thus protects the connected control unit from being used by unauthori-

 

zed persons.

 

When no password is indicated (default: empty) and AT+T Answer="On",

 

anything can be selected.

format

Data format of the RS232 interface.

 

Notation: DatabitsParityStopbits. Default: 8N1.

handshake

Handshake protocol for the RS 232.

 

Values: None, RTSCTS, XONXOFF

timeout

Idle timeout - Sets how long the connection remains available in case no

 

more data is transmitted.

 

The default value is 75 seconds.

 

A value of 0 switches this function off, that is, the Mitsubishi Super Modem

 

will not end the connection even if no more data is coming

RS232Speed

Data speed on the RS 232

 

between the Mitsubishi Super Modem and device connected to it.

 

Default value: 115,200 Baud.

Port

Remote interface to connect to.

Example:

The Mitsubishi Super Modem is configured for the TransMode:

AT+T SEND="TransMode; Password:sesam; Format:8N1; Handshake:None;

Keep:20; Baudrate:9600; Enabled:On; Com:MB"

When a call is being received, the Tixi modem connects the RS 232 to the connected device. All data is now transmitted in both directions as if the devices were connected directly.

6.4.3TransMode Login Command

To use the TransMode of the Mitsubishi Super Modem, these prerequisites must be met

￿The Mitsubishi Super Modem must be connected to a working telephone connection. That means you must be able to call it. (check first using a telephone)

￿Call answering on the Mitsubishi Super Modem must be activated (AT+T Answer="On").

￿The Mitsubishi Super Modem must first be configured using the TransMode command.

For access to a PLC connected to a Mitsubishi Super Modem a log in to the Mitsubishi Super Mode via a modem connection is required. Use a Mitsubishi Super Modem or any other modem for this purpose.

Send the login command for the TransMode command at the latest five seconds after CON-

NECTING.

There are two possibilities for the login command, which are described as follows.

MIM-G01, MIM-A01 specifications

Mitsubishi Electronics has long been a frontrunner in the realm of advanced technology, particularly in the development and optimization of automation solutions. Two of their standout offerings in the field of air conditioning technology are the MIM-A01 and MIM-G01 systems, which cater to both residential and commercial applications.

The MIM-A01 is an indoor unit featuring a sleek design that blends seamlessly with modern interior aesthetics. This unit is engineered for energy efficiency, boasting an impressive seasonal energy efficiency ratio (SEER) that significantly reduces electricity consumption. One of its key features is the V-Flow design technology, which allows for enhanced airflow distribution, ensuring that every corner of the room receives adequate cooling or heating. The MIM-A01 also comes with advanced filtration systems, including a high-performance filter that captures dust and allergens, promoting a healthier indoor environment.

On the other hand, the MIM-G01 represents Mitsubishi's commitment to high-quality outdoor units. This model is known for its compact size and robust design, making it suitable for a variety of installation spaces. With its advanced inverter technology, the MIM-G01 can adjust its cooling or heating output according to the changing conditions, thereby optimizing energy usage. One of its hallmark technologies is the Hyper Heating feature, which allows the unit to maintain its performance even at extremely low outdoor temperatures, making it ideal for colder climates.

Both units share a common thread of smart technology integration. They are equipped with wireless control capabilities, allowing users to adjust settings remotely via smartphone apps or smart home systems. This feature not only enhances user convenience but also facilitates better energy management by allowing users to monitor and control energy use from anywhere.

In summary, the Mitsubishi Electronics MIM-A01 and MIM-G01 systems epitomize modern air conditioning technology with their focus on energy efficiency, innovative airflow design, and advanced smart features. Whether for a small residential space or a larger commercial application, these units align with the evolving demands of energy-conscious consumers while delivering optimal performance and comfort. Their commitment to quality and advanced technology solidifies Mitsubishi's position as a leader in the HVAC industry.
