\r\n\t\t\t\n

Dual-tone multi-frequency<\/p>\n\n\n\n

The tones that are heard when you press the buttons on a touch-tone telephone and allows you to send data via PSTN (analogue telephone line). DTMF assigns a specific frequency (consisting of two separate tones) to each key. This is also the system that most emergency analogue telephones use to transfer information e.g., background call information.<\/p>\n\t\t<\/div>\r\n\t<\/div>\r\n\t\t

\r\n\t\t\t\tWhat does GSM and DCP mean?\t\t\t<\/div>\r\n\t\t\t\"arrow\"\r\n\t\t<\/div>\r\n\t\t
\r\n\t\t\t\n

GSM stands for Global System for Mobile Communication. The DCP stands for Digital Communication Platform and combines the GSM with the lift emergency telephone and machine to machine gateway.<\/h4>\n\n\n\n

The DCP has a power source and one internal battery capable to power a limited number of CAN devices (200mA max). When there are a number of CAN devices connected to the DCP it is necessary to add an additional power supply. As a rule of thumb, when a CAN splitter is needed, an extra power source may be required<\/strong>.<\/p>\n\n\n\n

A GSM unit is voice only, whereas GPRS is voice and data.<\/p>\n\t\t<\/div>\r\n\t<\/div>\r\n\t\t

CANbus (Controller Area Network) is a vehicle bus standard designed to allow smart devices (or nodes) to communicate. Designed by Robert Bosch back in the 80\u2019s, it was initially used by car manufacturers.<\/h4>\n\n\n\n

The bus is based in a serial transmission (digital data is sent bit by bit over time) using a differential voltage across a single pair of wires.<\/p>\n\n\n\n

To learn more about CANbus, you can read our insights article: What is CANbus?<\/a><\/p>\n\n\n\n

CAN does not send large blocks of data point-to-point from node A to node B. CAN network sends many short messages which are broadcast to the entire network.<\/p>\n\n\n\n

All nodes can transmit information to other nodes in the same bus and any node can be transmitter or receiver.<\/p>\n\n\n\n

There are many reasons why we use CANbus at MEMCO by AVIRE:<\/p>\n\n\n\n
