Termite Terminal - RS232 Interfacing

Termite is an easy to use and easy to configure RS232 terminal. It uses an interface similar to that of "messenger" or "chat" programs, with a large window that contains all received data and an edit line for typing in strings to transmit.

Termite Terminal - RS232 Interfacing - CompuPhase

Plug-in interface for pre-processing or alternative views of the data, logging received data to a file, adding a toolbar to Termite, and other functionality that you may think of.

Termite Terminal

It can also do ..
  • A history of commands that you typed, with auto-completion.
  • Support for non-standard Baud rates (MIDI, DMX512).
  • Data can be forwarded between two RS232 ports.
From -ITB CompuPhase - List of Projects Done

The free Hyperterminal seemed to be missing, Now new and better feature rich terminals are available - Here's one from CompuPhase who are our kind of people the EE kind. This terminal ought to help serial port SBC development.

Hilgraeve Inc and HyperTerminal Hilgraeve's data communications software and Internet-based services enable businesses to become faster and more competitive through the use of electronic communications.

RF ASIC MAXIM Semiconductor

Maxim's ASICs enable you to "lock up" or Protect a circuit-design intellectual property (IP). These can be used for creating solutions for Cellular, Handheld, Satellite Datacommunications, GPS, etc.

Maxim chips have a wide range of uses, especially in easily resolving Complex Analog and Mixed Design Requirements.

RF and Wireless ASICs - Maxim

"A two-stage 1.9GHz monolithic low-noise amplifier (LNA) with a measured noise figure of 2.3dB and an associated gain of 15dB was fabricated in a standard silicon bipolar transistor array. It dissipates 5.2mW from a 3V supply including the bias circuitry. Input return loss and isolation are -9dB and -20dB, respectively."

Antronics Ltd – Project Design Portfolio

Product design and development is for the Innovative Engineer. Here Antronics have on display, some projects and design ideas that have been realized.

Antronics Ltd - Project Design Portfolio

A product design by Antronic - The BT redcare alarm monitoring system provides continuous monitoring of a BT telephone line that links a professionally installed alarm system.

Antronics Ltd – Project Design Portfolio

Antronics Ltd - Embedded Systems Specialists

Consultancy Services to Clients developing Embedded Microprocessor Systems. Design and development of software/firmware for embedded microprocessor and microcontroller systems. Specialized in Products which need "M2M" applications; ie, "machine-to-machine" communications.

delabs Notes

In product development, the most important thing is to communicate and interact with the customer. To get the inputs very clear, goes a long way in customer satisfaction and project's technical success.
Even if the customer is not able to create a Black Box Specifications but is able to indicate the need or problem. Then you can arrive at the specs by incremental prototyping, to gather full requirements.

Wireless Gigabit Alliance - WiGig 60 GHz

Interconnects Devices and Computers on WiGig technology for High Speed Media Rich DataCommunications. Multi-gigabit wireless communications using the unlicensed 60 GHz spectrum.

Wireless Gigabit Alliance - WiGig 60 GHz

"The Wi-Fi Alliance and the Wireless Gigabit Alliance (WiGig Alliance) today announced a cooperation agreement for multi-gigabit wireless networking" - Wi-Fi & WiGig cooperate

Wireless Gigabit Alliance - WiGig 60 GHz

WiGig version 1.0 specification Includes data transmission rates up to 7 Gbps. Backward compatible with the IEEE 802.11 standard.

The WiGig specification will allow devices to communicate without wires at multi-gigabit speeds. It enables high performance wireless data, display and audio applications that supplement the capabilities of today's wireless LAN devices. - WiGig at Wikipedia

WiGig gets spec and Alliance endorsement

"WiGig offers connections of up to 7Gb/sec, but operating at the top end of the dial, 60GHz, makes for very short range. WiGig will carry over about 10 meters in ideal conditions,….."
