Device Addressing NI4100

TUTech

I'm upgrading an existing system to add a projector. Generally in a NI series you would define devices as 5001:1:0, 5001:2:0 etc.
But I'm seeing
dvDVD1 = 301:1:0
dvDVD2 = 301:2:0
dvDVD3 = 302:1:0
dvDVD4 = 302:2:0

dvCodec = 401:1:0
dvCam1 = 402:1:0
dvCam2 = 402:2:0

and 12 Dynamic Virtual Devices

dvLocalSystem = 0:1:0

Touch panels are (There are 4 touch panels)
dvTP1a = 10001:1:0
dvTP2a = 10002:1:0

These are likely cards inserted in the ICSNET card slots in the NI-4100. If you set the address dip switch to 25, the device number for the first card slot would be 301. IIRC, the devicenumbers for the cards would be sequential, which makes it unlikely that device 401 would be in 1 of the 4 slots in the NI-4100.

Could be there are other ISCNET devices in the system, connected through the RJ45 jacks. Or maybe, the original programmer just renumbered the 5001 device.

That's what I though originally but there are only 4 card slots. The devices actually go from 301:1:0, 301:2:0 up to 309:2:0 and then 312:1:0, 312:2:0 to 318:1:0, 318:2:0 and again 401:1:0 402:2 up to 403:2:0.
There must be another card frame or external boxes.

It is actually possible to change the master's integrated device number and I've actually seen it done once. But, it's rare. Sounds like you'll be going on a seek-and-destroy mission looking for some single card frame ICSNet boxes planted around the site.

What does the tree in NetLinx Studio identify as online devices? The code may not reflect the current physical topography, indeed it might be generalized code from another project just leftover. But if any such devices are online, STUDIO will tell you what they physically are, and with some judicious disconnections, you should be able to locate them and determine what to do with them.

To connect to the system and look at the Online Tree would be great but I don't have access to it. I'll have to wait until the guy gets back to me with the information.
