code 86 dr signal off

[Sprague M]

Got it running. The problem was a series of problems. We initially determined that it was the CRT/PUNCHER board. Replacing it made no difference (086 alarm). So the old board was put back in. Once I tried the RS232 tester on the machine all lights were lit with the exception of RD. Actually this did show a problem (but I didn't know that).
I purchased a cable from Shop Floor Automation. This solved the 086 alarm, but still would not recieve from computer. Replaced the CRT/Puncher board. Now all lights on the tester light up. Still not able to communicate though.
Hooked up another computer (engineering with MasterCam). Sent a program using MasterCam and it went through. Problem solved. Almost. It is either the serial port on the computer or the software. When transmitting the RD light barely flickers, does anyone know if this is anything that can be set up in the computer com port parameters? Windows 98 using PCDNC .

The key is that RD is lit or flickering. It might be a "flick" based on the size of the file and speed of the transmission. Pick a long file and make sure that you see the RD changing.

The 086 alarm is based on jumpers or port not being used; if the 086 alarm is gone, then our cable helped - (Nice cables by the way from SFA).

Again start by sending from the CNC back to the software (Mastercam). Is RD lit at the end of the cable next to the CNC? If not, then the machine might not be sending data.

Do the reverse test, take the tester and put it on the CN230; transmit from the PC and see if RD lights.

Give me a call if you need more help!
