I was planning on buying the Q50--but without the NC 50 for now as I already have a hard wired Niles Audio IR Unit that controls all my gear in another closet(none of devices have line of sight).
What I was getting lost in were terms like "2 way sensors", "Serial commands", "one way vs two way RS 232 control", "voltage sensing", etc etc.
Could someone tie in why these are necessary and what we lose if we dont have those available? I've got a basic idea but having a hard time putting it all together.
All those terms are only applicable if you are using the NC-50. The Q50 on its own sends all its commands as IR, like most remotes do. If you add the NC-50, you also have the option of using serial commands
for those devices which offer that option. Sometimes, for some components, there are more discrete commands available in the serial command set than there are in the IR command set.
This is only a consideration, of course, for components that actually accommodate serial control, which is accomplished through an RS232
or serial connector on the back of a device. If your don't see that type of connector on the back (it looks like the monitor connector on the back of your computer), the component doesn't allow serial control and none of this matters.
Some custom remote systems allow 2-way
communication within this serial protocol, although the Nevo system does not. An example would be: the remote requests some status call from the component, and then sends out the appropriate command given the component's response. So, when we say the Nevo system allows one-way
RS-232 communication, that means that your components can't send info back to the remote.
Finally, there are various types of sensors
that can be used with the NC-50 that are used to provide component info to the Nevo system. A video sensor attaches between the NC-50 and the component to let the Nevo system know when a video signal is being passed. A voltage sensor attaches similarly and lets the NC-50 know the power state of the component. (This is useful for devices that don't have discrete ON and OFF commands, where you don't want to send the POWER toggle command and inadvertently turn the device on/off.)
The important thing to understand is that you don't NEED any of these items- NC-50, sensors, serial control module. They are just accessories that expand the Nevo system to particular situations where these options are desirable.
I am curious about your situation and how you are planning to integrate the Q50 with the Niles IR unit. If you're already controlling everything remotely, what will the Q50 be doing?
