The exchange unit is driven by the Data Terminal Ready signal (DTR) in the RS-232 protocol. Assertion of DTR activates the microprocessor controller of the exchange unit, which then assists in establishing the desired connection or providing the specified service. Negating or disconnecting DTR ...
which also implements IrDA and RS-232 in a one-UART system, requires only three ICs: an encoder/decoder (ENDEC), an RS-232 transceiver, and an IR transceiver. TX lines for the IR and RS-232 transceivers are connected together, thereby eliminating the need for an analog switch. Similar c...
Since the serial port is being used for communication to 2-wire devices in the reference design, three main things need to be addressed to allow communication between the PC and the microprocessor. What is going to be used to shift the RS232 signal levels to levels the microprocessor can h...
The VideoGhost Max HDMI is an innovative tiny frame-grabber, hidden inside a standard video cable. It may capture the HDMI video signal of a computer or laptop. The built-in powerful FPGA chip and microprocessor enable it to convert the captured video signal to a JPEG image, and store it...

The TC-36-25-RS232 requires an input voltage anywhere from 12 V up to 36 V. That voltage powers the microprocessor and can also be modulated and sent to the thermoelectric device. However, if the thermoelectric cooler or Peltier device operates on a voltage lower than 12 V, a second low...
The MDB-RS232 is a microprocessor controlled hardware interface with embedded firmware that converts the MDB protocol to an RS232 protocol and also performs the necessary voltage conversion. The MDB-RS232 also relieves the Polling requirements thereby allowing the same PC to perform other tasks. ...
