Somebody tried before to solve it but the result was 0 and now I see that the serial port 1 of CNC is damaged.I use the standard db25db9 cable described in fanuc manuals, software handshacking.Can I use the second serial port through channel 2 with appropriat parameters setting to communicate with the PC 2.To transfer files it is necessary to use a dedicated program or it can be made with a common serial communication software, eg terminal,hyperterminal,etc 3.When I want to read files from the PC, after pressing read,filename,exec the screen has no change, no blinking LSK, norinput on lower right corner and no errors Why Same when trying to punch Par.
Cnc Rs232 Communication Software Serial Port 1You use 9600-E-7-2 so your PC-COM software needs the same setting. Now I understand that I can use channel 2 for updownload, the cable from the db25 on the cabinet I plugged into serial 2 on the CNC respectivley to JD36B. It gives no more err086 but after the key sequence read,oxxxxx,exec,nothing happens on the screen, no indication that the CNC is waiting for signal from PC.Is that normal Best regards, microplus.

Cnc Rs232 Communication Software Free Assistance ForHowever, we can not offer free assistance for configuring or using your machine control. In most cases, extended technical support or on-site service may be purchased to address these issues. Cnc Rs232 Communication Software Trial When InstalledKeep in mind that both FocalPoint and Easytalk provide a free 10-Day trial when installed on a new PC. The DNC software is much more flexible in how it receives data and will not issue Alarms and halt transfer as machine controls will do. Furthermore, the nature of the data received may help you identify the source of the problem. Check the cable configuration at the machine end, particularly pins 6, 8, and 20. The cable should have a jumper between pins 4 and 5, or they should pass through to their compliment lines on the computer end. If hardware handshaking is being used and your cable requires pins 2 and 3 be swapped (null-modem) then pins 4 and 5 will also need to be swapped. A simple loop-back test as described below will verify correct operation. You could also t ry sending to FocalPoint from a known, good machine to validate proper operation of the serial port(s). Many machines have a parameter setting to select between EIA and ISO. Other possible sources of junk characters are long or unshielded cables, cables with poor connections, cables running near EMF sources such as transformers and florescent lights, or more commonly, improper grounding. Many controls require an end of block at the beginning of the file or require a program number at the beginning of the file. Check the controls manual for program termination codes such as decimal 04 character. Some controls also require a M30, M02,, or the END statement at the end of the file. This setting is accessed from the Windows Control Panel and is discussed in the Windows help program as well as FocalPoints installation notes. If the cable uses only pins 2, 3 and 7, select X-ONX-OFF protocol. Also referred to as Software Handshaking or DC1DC3 control codes.) If the machine is old and does not support software handshaking, use a cable with pins 4 and 5 connected. It does NOT validate proper cable wiring or determine the correct RS-232 parameters for communications. This represents the character being transmitted and the echoed (received) character as jumped on the loop-back connector. Note that some device hardware may terminate with a RJ-45 connector. If so, use the device-supplied, loop-back plug or substitute a known good cable. Note that some controls allow you specify different ports and device types for both Send and Receive. Refer to your control manual for instructions regarding port setup and configuration.
