Laptop computer COM port and USB connection can only be one way to send data,
Notebook computer use USB interface to connect a USB turn 9-pin male head of the line, after a double 9 pin female head of the line, to connect to a PC com port, the test data transmission,
After open the serial debugging assistants, found from a laptop to send data to the PC serial debugging assistant, the receiving area on both sides of the information can be seen, but send information from the PC to the laptop, the laptop's side will have no reaction, what a great god help solve,
Who is win732 notebook system, using line is 23 to pay even 5 direct line (self-control, bought a standard double female head of the line, but can not send messages on both sides)
Recognize the notebook the com driver is a USB SERIAL CH340, installed along while prolific drive, feeling is not compatible, (don't know if this problem,)

Remove the serial port, serial port 2 or 3 short answer, and then send the data to see the function cannot receive data, on both sides of the computer all such tests, CH340 cheap but have compatibility problems, can change other chips try turn USB serial port, such as Z - TEK ZE533

After testing, all pass, don't know why, I finally made a line again, ok, can transfer on both sides, but now with a serial port for instrument, how also can not get the HL7 data format is under study,,,

Mindray testing equipment? There is no data or gibberish?

Beckman biochemical analyzer AU480, now just connected with serial debugging assistant see access to data, only hexadecimal, ASCII and utf-8, tried the along while have no I want the HL7 format of the data, don't know what's the matter, are working on?

Beckman biochemical analyzer AU480, now just connected with serial debugging assistant see access to data, only hexadecimal, ASCII and utf-8, tried the along while have no I want the HL7 data format, don't know how to return a responsibility, is research,

I now is what circumstance, is our boss to do the LIS, but we didn't do the LIS, just let me study, javaweb, but I do not contact with the LIS, and now is indeed a hindrance, can only take a biochemical analyzer, can try to read data, difficult online at the beginning, the company without a serial port cable, I asked suppliers make their own line, problems appeared in the post beginning, then repair and can transfer data, but according to my knowledge should be the HL7 data patterns to resolve, but how can I use a serial port assistant also does not have that kind of format, also could not say anything to ask supplier, the machine didn't people understand, hardware and software, and sad, are each the thinking of how to get this thing, a great god if have time, whether can give me that way?

Agreement I want to come, the problem is that I serial debugging, just don't get the format of the HL7 data, I to you with AccessPort, inside to open the Hex, hexadecimal, left is right, it is not a HL7 format, sorrow, I began to doubt or USB interface,

Baud rate is 9600, on both sides ASCII and utf-8 basic it is garbled, only hexadecimal is normal, with AccessPort right is the basic format DBD 000601 0001 E093 Hr120 5.56 5.47 HrD 000602 0002 E093 Hr120 HrD 000603 0003 E093 Hr120 5.53 5.50 5.51 5.58 Hr
