Is originally wrote a serial communication program, according to the communication protocol is configured in and send the request to get the data of 8 hexadecimal code, but wood reaction,,,, ever do this aspect of the great god of!!!!!!

CodePudding user response:

With a serial port debug tool first commissioning, the commissioning in to ask

CodePudding user response:

Pal, I have written the program, and is written according to ge a serial port communication protocol, also in the local test, itself serial program can I talk to online serial debugging assistant program to communicate with each other, there are no mistakes, just don't know whether I connect the monitor itself have any requirements, hope the great god,

CodePudding user response:

Well, doing a test, connect the monitor on the local computer

Use a serial port test tool is directly connected to the monitor, and then send the instructions on the document in the past, look at what returns no

CodePudding user response:

This I also tested, I write my own demo on hardware connection monitor, just send the request to get the data of instruction, then don't respond, then I'll use serial debugging assistant program test the connection again, and take the initiative to send the request to get the data of the instruction, the picture above public three instructions to get data, respectively is the request for real-time data interface, request waveform data, the 60 s trend data, are tried,,, the main problem is that I don't know what to monitor there whether there is a set, also asked with ge after-sales personnel, they just said the document, in accordance with the above operation, are completely covered circle now,,, don't know why the monitor is no feedback, I am sure I am according to their agreement document to send the instruction in the past, coding format is also calculated there is no problem, ask the great spirit guide

CodePudding user response:

First look at your equipment can use

CodePudding user response:

Then see no, manufacturers have a demo with factory demo test, if the factory cannot run the demo, it's only manufacturers remote assistance to see

If the manufacturer can demo, factory demo configuration configuration to the virtual serial port, use a serial port debug tool to see manufacturers send instructions exactly have what different,

CodePudding user response:

1. The same 6th floor, to ensure that the hardware is no problem for the next step
Before met, a serial port debug impassability, changed after a thread to solve,

2. A serial port communication, configuration is more important, these need to be in accordance with the manufacturer's documentation to go with
Com port, baud rate, parity bit and so on must be accurate

CodePudding user response:

Manufacturers said no,,, this is the most let me helpless,,, I told them a lot of phone calls are not in the things then just send me a communication protocol,,,

CodePudding user response:

Hardware configuration I know here, but also to match according to the current agreement, line is in accordance with the requirements for the buy aten us232a, is now a direct no idea,,,,

CodePudding user response:

That just turn the usb serial port line, installed driver can

In fact, if you have a serial port on the machine, you can directly through a serial port, don't have to use usb line

CodePudding user response:

Some, also tried to turn the usb serial port is for the convenience of instruments and laptop connection, the first is to use the serial port, later found on the communication protocol to use this line, but also a serial port to the computer, monitor, usb port, and have no idea, you have done similar project? Have not encountered this kind of situation

CodePudding user response:

Make sure the hardware to ensure that the hardware is no problem to debug software, serial port this stuff is really a headache, need to slowly try

CodePudding user response:

Or can't, no progress, and hardware testing is good, after connecting the monitor or: sent instruction without any data feedback, line also changed several root, both direct and cross are tried, completely is no idea,,,

CodePudding user response:

Just finished omron monitor via a serial port for data development, GE 650 monitoring data acquisition, is preparing to do you have any idea to solve the building Lord, take GE of the interface documents sent, maybe we can solve together

CodePudding user response:

Device Monitoring Studio, with people's routines,

CodePudding user response:

14 floor, Pal, you do this interface of the document?

CodePudding user response:

Pal ask official whether the monitor supports data output function, Europe and the United States of S/5 monitors, we are also the same problems anyway countless according to output, tried a few units are the same, can't

CodePudding user response:

On the 14th floor gold1999

GE 650 I have development documentation, you have other brand development information? Share with each other under the

CodePudding user response:

B450 serial me out, with the green of the serial port, the computer system win10 displacement, free words b850 like 650 and 450, but now is not out,

CodePudding user response:

# 21 Pal, you can now from B450 machines obtain not decoded data? My side is no response,

CodePudding user response:

refer to 21st floor dingkuan3205 response:

B450 serial me out, with the green of the serial port, the computer system win10 displacement, free words b850 like 650 and 450, but now is not out,

You can get to the B450 data? Take the liberty of asking, you use a pure serial port or serial port turn U mouth? And you are sending in the development of documents to get the data byte instructions get? My side is stuck in here, send the instruction don't respond, also tried a lot of lines

CodePudding user response:

Usb serial port, usb monitor, a serial port plugged into a computer, is according to the instructions of the S/5 communication protocol to send,

CodePudding user response:

reference 24th floor dingkuan3205 response:

usb serial port, usb monitor, serial computers, is according to the instructions of the S/5 communication protocol to send,

Brother, you can get directly to the data over there? I also the same operation, sending the instruction, is not do ah,,,

CodePudding user response:

My side is B650 oneself write a serial port demo but can only access to the data, using a serial port debug tool online but take less than at a time

CodePudding user response:

Sure good, baud rate, and then according to their document hexadecimal data to see if the same, then the data,

CodePudding user response:

My side is B650 oneself write a serial port demo but can only access to the data at a time, using a serial port debug tool online, instead of a is less than, autumn autumn dress 6 up 5 insect 2 3 open 24419
Why is the monitor data send only one very old fire

CodePudding user response:

reference If_I_love_you 26 floor response:

is on my side B650 oneself write a serial port demo but can only access to the data, use Internet instead of a serial port debug tool once get less than

It is better than my side is good I just can't get data, whether to write their own demo or serial debugging assistant, Pal, convenient in detail the steps you connect the monitor? And send instructions, seemingly manufacturers there send me the interface of the document is general B450 B650 B850, I had sent instructions in the previous screenshots, you look like you? I'm very want to get the data, even if one is progress it
