I'm interested in knowing more about what you see as the advantages of using the NX-587E and/or deficiencies in the com port based solution. Overtime I've fixed and added capability to the com port based module set.

The standard modules, or the ones I've modified and put in the file section, use the automation com port either the integrated one on the NX-8E or the NX-584(E). And since most of the things that we've done with it are done in Simpl, it is easier on the processor as well as a programmer that isn't as skilled with Simpl+. Also, since the protocol is open you can build a module that does exactly what you want - within the confines of the keypad module of course - and not be stuck with what someone else has written, unless you're lucky enough to have a copy of the protocol document and the time to modify things. Last, there is much less communication between the Crestron and GE system and you can tell the module what you want to see dynamically instead of having to enable things in the setup of the security system which is nice. Granted, you can do most all the functions with the serial port modules but you do have to emulate the keypad text with the Crestron Modules (not sure about your modified ones). No more explaining to the security guy why you have to turn on certain options!Īnother benefit is it emulates the text on the keypad, along with all the other functions so if your interface is setup like a GE keypad the homeowner can use it like their existing GE keypads, and the manual for the GE keypads works with your Crestron interface, too. We just started using the Keypad Emulator and really like it.įor one, it is much easier to setup - just hook it up on the keypad bus, enter programming then exit and the module is enrolled.
