Serial RS-232 datalogger

Serial RS-232 datalogger

Serial RS-232 datalogger

(OP)
Hi,
I want to record an RS-232 data obtained from a serial port into a memory chip, and then to download it later onto a PC using the serial port and the Windows HyperTerminal (ASCII-format). This is basically a special type of a dataloggers.

Do you know any company that has this kind of datalogger? or good resources to make one from basic components?

Thanks

RE: Serial RS-232 datalogger

Hi, dead easy to do yourself.how much data do you want to store?

RE: Serial RS-232 datalogger

(OP)
Hi,
I need about one megabytes of memory. Please let me know how can I build it myself.

RE: Serial RS-232 datalogger

Hi, a megabyte! thats a lot of ascii data, how r u going to read all that on hyperterminal?

RE: Serial RS-232 datalogger

(OP)
Hi. This is not really the problem, I will actually use another software to get the data - other than the Hyperterminal. I want to design the datalogger to record up to 1MB of data, I might not use even half of this size.

RE: Serial RS-232 datalogger

Hi, you need to work out what exactly what you want. A micro, a memory and some trivial code is all you need.

RE: Serial RS-232 datalogger

(OP)
Hi, do you know a website that has a schematic diagram of the circuit (or something close to it) with the name of components? I'm a beginner in electronics!

RE: Serial RS-232 datalogger

Wouldn't it be better if you tried to do it yourself, and come back with specific questions?  In the long rung, it won't do you too much good to copy someone else's work since you won't have gained the experience that comes from designing the circuit / system.
