USRIOT USR-GPRS232-710 module. GPRS module DTU (data transfer unit) is a wireless terminal equipment that converts serial data into IP data or serial data, to be transmitted through the wireless communication network of GPRS mobile telephony. It allows the transmission of data under the TCP/IP protocol using GPRS technology. It allows to transmit through virtual private networks. It allows the transmissionn serial data RS232 and RS485 through the GPRS mobile telephone network.

DIN Rail

A DIN Rail is a metal rail of with standard size of 35 mm wide. (A)

It's commonly used on installation and assembly of electrical devices or controllers for home or business use.
Besides the typical DIN rail 35 mm x 7.5 mm, can also be found in other measures as:

- Mini DIN Rail, size 15 mm x 5.5 mm (B)
- DIN Rail, size 35 mm x 15 mm (C)
- G section, size 32 mm x 15 mm x 8mm (D)

These rails are designed for installations with a method of simple, fast and configurable fixing. Ideal for installation in electrical distribution points, distribution of telephone wiring, alarms, digital electric programmers, keystone adapter, attenuators and any other compatible device.

DC jack connector

Inside the different types of connectors for power supply we find one of the most common, the DC jack. Used in most connections in electronic devices such as routers, laptops, printers etc ... is the most used due to its easy assembly and connection. These connectors are mostly used in DC power supplies and installations.
The connector is cylindricalAnd we find its version in male and female format (A). The male connector is composed of the outer and inner metal part, where in each of them the energy travels, normally the inner part is used for the positive pole and the outside for the negative, but may vary according to manufacturer.
This type of connector is found in many diameters, the most common are 3.5mm and 5.5mm. Although we can andThere are several measures in terms of length and outer or inner diameter.
Its installation is simple, we can find several types of connectors, pair to weld or to screw with terminal block, it will depend on the user to choose the most suitable in its installation.
When purchasing the male connector to perform a repair we must know its diameter, length of the connector and internal diameter. If we proceed with aTo new installation only we must make sure that the male and female connector are of the same characteristics.

The DIN is a standard that was developed by the "Deutsches Institut für Normung" (one might call the national standards organization in Germany). The DIN is facing many sectors, but we have tried to focus on the DIN-oriented electronics and computing. In the case of Enclosures means qualifying under the German legislation on racks and is standardized to DIN 41494-7.



General Packet Radio Service (GPRS) or general packet radio service created in the 80s is an extension of the Global System for Mobile Communications (Global System for Mobile Communications or GSM) for the transmission of data by packet switching. A similar service for mobile phones, the IS-136 system. It allows transfer rates of 56-114 kbps. These Class A devicesThey can simultaneously use GPRS and GSM services. Only Class B may be connected to one of the two services at all times. While GSM service (voice or SMS) is used, the GPRS service, which automatically restarts when the GSM service ends is suspended. Most mobile phones are of this type. Class C are alternately connected to one or another service. Switching between GSM and GPRS shouldperformed manually.

The global system for mobile communications (English Global System for Mobile communications, GSM, and originally from the French groupe spécial mobile) is a standard system, royalty-free, digital mobile phone. A GSM client can connect through your phone to your computer and send and receive emails, faxes, surf the Internet, access to the computer network security acompany (LAN/Intranet) and use other functions of digital data, including short message service (SMS) or text messages. What are the differences between GSM and UMTS? The GSM system operates by TDMA, ie, time is divided into slots and each user is assigned a slot, ie, a period for which data can be transmitted. Therefore each channel is shared by a ndetermined number of users. The system is a UMTS (WCDMA) code division multiple access broadband. In this system there are no time slots and GPRS. All users transmit simultaneously on the channel, but each user signals are encoded with a unique code so that even though we think that an "indecipherable signal" is formed by using the same frequencies simultaneously, It is not toyes, because the base station is capable of decoding and re perfectly separate each of the communications received from different users. This obviously implies a much higher channel utilization, to not share in time.

Communication Series

RS-232 (Recommended Standard 232, also known as EIA/TIA RS-232C) is an interface that designates a standard for the exchange of a series of binary data between a DTE (Data Terminal Equipment) and DCE (Data Communication Equipment , Data Communication Equipment), although there are others in which the RS-232 interface is also used. An equivalent definition published by the ITU is called V.24. The RS-232 is a connectorDB-25 type (25-pin), although it is normal to find the version of 9-pin (DE-9, or popularly also called DB-9), cheaper and even extended to certain types of peripherals (such as serial mouse PC).

It is a special multi point communication for industrial machinery by its format adapted to long distance and heavy machinery. The connector is used to connect the DB9 serial port or popularly called. One characteristic is that it is able to greatly reduce the noise so that the distance is much greater.



The term refers generally to control the amount of flash light emitted by the measuring light when returning to the same flash sensor through the lens. In TTL flash metering it occurs after the shutter has opened -the sensors record the amount of light created flash back to the camera through the lens and flash (\ turns off automatically "cooling" ) when you haveproduced an adequate amount of light.
