| 841485 | 2009-12-21 09:41:00 | hey was thinking would i be able to use hyperterminal to receive and send the files on a laptop? HyperTerminal should do fine (maybe very slow, though - how big are these files?). So we are talking RS232, right? The connectors on the PC should be male for serial & female for parallel. I'm pretty sure you can get away with a simple 3-wire cable - cross over pins 2 & 3, and wire 7 to 7 (for ground). Dick Smith used to do a full null modem suitable for hardware handshake, but the market for them has died, so doesn't appear to any more. You can use XON/XOFF handshaking for 3-wire cable - but I think probably won't matter if you use X/Y/Zmodem for the transfer, as those protocols have handshaking built-in (you may have to choose "none" to get it to work if you don't have the RTS/CTS/DSR, etc. lines hooked up). |

| 841486 | 2009-12-24 09:43:00 | Hi this is my suggestion. If the CNC machines work OK then dont try changing or using unknown cables as you may damage them for life and make them unusable or send the software into a state you may not be able to recover from. You mentioned not wanting to unplug cables from hard drive this indicates you are walking "no running" into the unknown. Suggest you work from following as unpluging hard drives is much easier than trying to work out send / receive logic. If its not broke dont touch it without evaluating the risk?? What are the CNC brands Are they the same. Are the connectors the same Has your uncle ever been able to do what he wants to do, or know of someone else. Are there screens for entering and saving data for future recall for machining different items. Search the web for CNC details and manuals for the CNC machines. You will more than likely find a solution quicker as well. |
