"You have a sample with a concentration of 1x106 bacteria/ml and you wish to know how many of these bacteria are viable. You dilute the sample down to a single bacterium/ml and plate 100 microliters of this diluted sample onto an agar dish. After incubating the dish for two weeks you count...

This is my first post. I am an aerospace engineer so these very technical computer questions still elude me. My question is mostly about RS422 standard. I have a piece of equipment (LIDAR) that is able to transmit data via a 9 pin serial port. If you put a jumper across two of the pins it...

hi, may i know how to control IC 74165? What is the purpose of this 2 clock? i need a IC which can transfer 8 bit data from parallel to serial, got any suggestion?

Good afternoon! To build a serial connection of two transformers, four coils are used: Two of this coils have n1 turning, two of them have n2 turnings. The coils are built together in the way, you can see on this picture: http://img197.imageshack.us/img197/2698/transformer.jpg The...

Hi, I have a cooler and a pressure gauge which I need to operate from Matlab. Both devices are connected to the computer via a serial port. I've been using the Matlab Instument Toolbox Test & Measurement tool to try and communicate with these machines. The problem is that I don't get any data...

Hi and thanks for your help I have a table in Excel spreadsheet which is containing data to motor through a stepper driver I can convert this spreadshhet by save as CSV file, the problem I have know is to write a programme in MS DOS throgh windows to send this CSV file to the serial port and...

Homework Statement Why is serial data transmission preferred over parallel transmission when needing to transmit data over vast distances? Homework Equations The Attempt at a Solution I think this has many different reasons...but I'm trying to pinpoint important ones. -I think...

Hi everybody, I have a very simple question for programmers and automation professionals, My friend told me that I can use the program National Instruments LabView as an Oscilloscope through the serial cable! Is this true? and what are the limits of this advantage? I'm using this...

Hello all, newbie here Google led me to this thread: https://www.physicsforums.com/showthread.php?t=70094" which happens to be basically my question. I am doing an investigation on Hooke's Law for my VCE Physics class (Australian year 12, senior school). Thanks to wikipedia's derivation...

Hi I am using RS-232 connection to may FPGA, and I want to send information from matlap. Whan I set may VHDL program to the defult seting of the RS-232 which have 9600 bit/sec, then may FPGA show the data correctly. but whan I change the VHDL program and the matlap seting to anthor...

Hello All, I have a circuit that uses a microcontroller to communicate via a three-wire serial line (SPI) to a DDS chip to send and receive commands and status information. My question is that if the DDS IC happens to be on a different board and I want to galvanically isolate them from each...

Hello, I've been writing a program to communicate with an embedded system via rs485 The protocol in use utilizes stick parity, where stick parity is defined as the first byte (which corresponds to the address of the device) having its parity bit set to 1, and the rest of a packet have its...

Hello All, I am currently trying to figure out how to program the AD9959 IC using a serial connection to my PC. From reading through the datasheet for this chip, I learned that it uses the serial SPI interface to send and receive instructions and data. This chip has four channels of DDS...

Hello all, I am trying to communicate with a rs232 device using VB. however, testing my program by using hypterminal, I noticed that any time I try to output an ascii character 128 or higher, it shows up as a '?' instead of the desired character. I know hypterminal is able to display...

In my C book it says that the serial port is stdaux, but when I make a program to send data to stdaux the compiler (Dev-C++ in Windows and gcc in linux) says that stdaux doesn't exist :frown: Can anyone explain or point me toward a good tutorial about using the serial ports in C? Thanks

I have an old serial port joystick but no serial port on my computer i am pretty sure there is a way to connect the serial port to a usb adapter does anyone know how to do this? thanks

First take a look at the attachment (See reply below). We have to take the oscilloscope's impedance and the coaxial cable's impedance into account. And then we have to calculate the cutoff frequency of this. Given: Oscilloscope: R=1M Ohm // C=25pF Coaxial Cable: R=75 Ohm and C=68pF/m...

Is it possible for a baby to be born with the Genetic makeup that will cause that child to grow into being a serial killer? Possible but probably not very probable. Did a lousy childhood bring this behavior about? Good possibility. But what could be other causes to bring about such an...

The Nobel Laureate P.W. Bridgman commented on Einstein’s theories of special and general relativity. He said that more analyses should be given to the events of the theories rather than analytical attacks on the coordinate system used in specifying the physical events found in the theories...

Is anyone else here a big fan of the anime series "Serial Experiments Lain"? personally, i think it rocks, though it also manages to make The Matrix series look simple and straightforeward in comparison.

I saw an advertisement claiming 1.5Gbps could be obtained from this new? hard drive technology. Sounds pretty fast to me. Anybody have one or know more about it? Will it be a cornerstone for the next wave of computer advancement?
