The E232 photos page might be of some help, but the cable shown is not the cable wiring you want. Put the computer program in receive before you send from the HAAS. 9600, 7 data, 1 stop, even parity, and XON/XOFF.ĭoing this see if you can receive anything at the computer. I know nothing about your RS232 receive program, but it needs to be set to the same values for RS232 as the HAAS machine. Hopefully you have a real RS232 port on the computer and not a USB to RS232 adapter. If the above test shows that you can send data then connect your cable from HAAS to the PC. You should be able to ignore all other pins. The wiring from the 25 pin to the 9 pin should be pin 2 to pin 2, 3 to 3, 7 on the 25 pin to 5 on the 9 pin connector, and HAAS pin 1 to the shield. If your cable has a shield it should connect to HAAS pin 1. Now send a program from HAAS the voltage will drop to around +/-1 V while data is being sent. Measure the voltage from pin 2 to one of the 4-40 studs, which are at essentially the same voltage as pin 7, common. Get a DC voltmeter with a 10 V or slightly higher range. Use pin numbers 2, 3, and 7 on the HAAS RS232 port 1 connector. You are only interested in port 1 for program communication.įor now use 9600 baud, 1 stop bit, even parity, XON/XOFF, 7 data bits. Then go to the next one that needs to be changed. After picking the value for a selection use the WRITE key to save the selection. Here use the cursor keys to change any of the values required. Now page down about 4 pages to get to the RS232 settings. To make things simple at the HAAS end just go to the SETTINGS page. There are others that use DNC to mean Distributed Numerical Control and in their language that includes sending and receiving. I simply refer to what you currently want to do as 'communication' or 'serial communication' or 'sending' and 'receiving' files (programs). In my dictionary and HAAS's the acronym DNC stands for Direct Numerial Control.
