Need a extra RS-232 port looking for options

Kouya · September 2006

I have a NI-2000 as the master, ran out of RS-232 ports the only options I see is getting a NXF-mini and NXC-com2 cardframe and card. Or possibly using Axlink to a AXB-EM232.

Is there any other box that can give me the extra RS-232 port?

Thanks

The only other options that come to mind are adding another processor (NI-700) or using an RS232 to Ethernet adapter. Using the ethernet adapter may cause you additional programming or other issues.

Hope this helps,

I would buy an Axcent3 on Ebay, and slave it. That will give you 6 more serial ports, 8 IR, etc. It's not a bad way to expand a system at all.

I've actually been looking at these guys www.globalcache.com, aparently there is a Netlinx module to control their pieces, so it's a cheap way to get extra IR and serial ports.

I was looking at those myself, not long ago. If it must be new equipment and an RS323 box is out-of-budget, that might be the way to go; if they are cheaper than an RS232 box, that is.

If you don't need two way RS232 you can always use an IR port with the new firmware and do one way RS232 communication.

A great solution !

I have done this several times with success.

This works great when you dont need true feedback from a device.

Thanks Guys

Great ideals and solutions. I'll try the IR since it's available and I'm not using feedback.

Alexanbo Thanks for the Gobalcache link, some of their stuff might be worth having in toolbox for emergencies.

A truly wrong but workable solution is to use the programming port.
I've never done it myself but have seen it done.
It will totally mess the heads of any third parties trying to connect to it.

Add a ?relay-controlled 1 to many serial switch and select the destination before sending the command.

(Yeuch)
