Can anybody explain what it means when the port LED stays lit red when I plug a new serial module into the NC-50?

I'm trying to add a new device and that light stays on and my NC-50 won't operate properly. I go through "Find," etc. and it says the NC-50 was updated successfully, but it just wants to keep cycling through the Find procedure. It won't actually send commands to any of my devices. None of the other lights with attached devices stay lit like that, so I'm just wondering what the light indicators mean...

TIA!

Make sure the minipin is plugged all the way in...

I thought I did. It appears to be inserted the same as the others.

Does the red light indicate a poor connection?

well, it could be that you need a null-modem (i.e. Tx/Rx lines need to be swapped)...

Hi,

Red represents output.
Green represents input.

If it is red then it is more than likely not connected correctly. Check all the connections relating to that cable.

Have you plugged it into another port?

Thanks for the explanation. That's really what I was looking for, and yes, it turns out that the mini-plug needed to go in an extra "click," even though it looked like it was in all the way.

I make my own adapters, and this setup did require both a null-modem and male-male connection. Is there NO standard in this stuff??? My Denon processor is the only device that I have where I was simply able to plug in the Nevo serial module as is. Everything else requires an adapter of one sort or another. Do the other remote systems tend to put female DB9 connectors on their cables? These male-to-male connections are a PITA, as I end up with a 5-6" connector hanging off the back of most devices. :(

Hi,

Welcome to the world of RS-232. There is no standard.

The current Nevo cable is the industry standard.

I have a handy box with heaps of NULL adaptors and Male/Male, Male/Female adaptors. Something like these [Link: expansys.com.au]

E#@y has the best prices.

Sorry for the language :)
