I have been trying to setup the RS232 port on a mill. I have confirmed cable connections are correct (I have used the null modem cable without handshake) and I am still getting a SR830 Error. I have come to the conclusion that the RS232 connection on the main board must be fried. It seems like installing an option 1 card would be the cheapest way to fix this problem the cards are only about $350 on ebay. Are there any parameters that must be changed to enable the option 1?

My machine did not have one originally so I am assuming that some parameters will need to be changed, but I have ordered the card and am hoping that I can just plug it in.

If anyone knows anything about installing this card I would appreciate any information.


I am also new to the forum so if I am sorry if I should have posted in another location.
