Product and Interface Descriptions

Ethernet Interface

The MultiModem wireless modems with an Ethernet interface provide shared Internet access with one IP address. The built-in routing capabilities provide DHCP services and firewall security using Network Address Translation. Due to the routing capabilities, these modems are sometimes called routers.

These modems support "always-on" network connection as well as "dial-on-demand" for Internet services. The "always-on" network connection automatically establishes a wireless data connection and allows for around the clock surveillance, monitoring or real-time data acquisition of any remote Ethernet device such as a Web camera. If the data link is dropped in the event of poor reception or a complete loss of service, it will automatically re-establish the data link. When configured for "dial-on-demand" the wireless modem only accesses the Internet when data is present. This configuration is ideal for sharing Internet access among networked PCs.

Software features include remote configuration, firmware upgrade, load configuration screen, and a save configuration screen.

MultiModem EDGE

The MultiModem® EDGE wireless modem delivers some of the fastest cellular wireless data speeds utilizing EDGE technology. It allows users to connect to the Internet and send and receive data up to three times faster than possible with an ordinary GSM/GPRS network making it ideal for highly data-intensive multimedia applications. The MultiModem EDGE wireless modem is equipped with quad-band GSM, which means it can be used worldwide on all existing GSM networks.

AT Commands: The MultiModem EDGE wireless modem is configured using the EDGE AT Commands. These commands are documented in the Reference Guide for the MultiModem Wireless EDGE Modems, document number S000371x.

MultiModem GPRS

The MultiModem® GPRS wireless modem offers standards-based multi-band GSM/GPRS Class 10 performance. The ready-to-deploy, standalone data/fax/voice modem allows developers to add wireless communication to products with a miniumum of development time and expense. The MultiModem® GPRS wireless modem is base on industry-standard open interfaces and can be desktop or panel mounted.

AT Commands: The MultiModem GPRS wireless modem is configured using the GPRS AT Commands. These commands are documented in the Reference Guide for the MultiModem Wireless GPRS Modems, document number S000293x and also the Reference Guide for the GSM IP Commands, document number S000333x.

MultiModem CDMA

The MultiModem® CDMA wireless modem offers standards-based multi-band CDMA200 1xRTT performance. The ready-to-deploy, standalone data/fax/voice modem allows developers to add wireless communication to products with a miniumum of development time and expense. The MultiModem® CDMA wireless modem is base on industry-standard open interfaces and can be desktop or panel mounted.

AT Commands:The MultiModem CDMA wireless modem is configured using the CDMA AT Commands. These commands are documented in the Reference Guide for the MultiModem Wireless CDMA Modems, document number S000294x.

RJ-9, RJ-45 specifications

Multi-Tech Systems offers a range of communication solutions, prominently featuring the RJ-45 and RJ-9 connectors that are crucial in networking and telecommunications. These connectors are foundational to many applications, enabling efficient data transfer and ensuring reliable voice communications.

The RJ-45 connector is primarily used in Ethernet networks. It features eight pins and is designed for high-speed data transmission, making it the standard for wired local area networks (LANs). This connector supports various Ethernet standards including Fast Ethernet (100BASE-T), Gigabit Ethernet (1000BASE-T), and even 10 Gigabit Ethernet (10GBASE-T). An essential characteristic of the RJ-45 is its versatility, as it can be used with both straight-through and crossover cable configurations. This flexibility allows for straightforward connectivity between devices such as computers, routers, and switches.

Multi-Tech Systems employs advanced technology in their RJ-45 connectors, including support for Power over Ethernet (PoE). This innovation permits electrical power and data to be transmitted over the same cable, simplifying installations and reducing the need for additional wiring. The robust design of these connectors ensures durability and minimizes signal interference, thereby maximizing data integrity during transmission.

On the other hand, the RJ-9 connector, also known as the RJ-9 or RJ-10 connector, is typically used in telephone and headset applications. Characterized by its smaller size and four or six pins, the RJ-9 is optimized for voice frequency communication. It connects devices such as telephones, headsets, and other VoIP equipment, delivering clear audio quality that is essential for effective communication.

One standout feature of the RJ-9 connector is its ability to provide superior noise resistance, making it ideal for environments with significant electromagnetic interference. Multi-Tech Systems' RJ-9 connectors are designed for ease of use, allowing quick and simple connections. These connectors can often be found in various telephony devices, ensuring that they remain a staple in personal, commercial, and industrial communication systems.

In conclusion, Multi-Tech Systems continues to lead in the provision of reliable RJ-45 and RJ-9 connectors, integrating innovative technologies that enhance performance in data and voice communication. Whether in a high-speed networking environment or in everyday telephony applications, these connectors deliver the functionality and quality demanded by modern users. Their design and engineering reflect a commitment to excellence, helping users stay connected in an increasingly digital world.
