Guys, for alot of the modules in the crestron database that aren't simpl plus modules and aren't "system builder" compatible it is real easy to do it. Open up SIMPL. Find the module you want, right click on it, and choose edit this module in this instance. Add in a virtual serial driver for macro connection. Put in a TX$ (on the tx$) put in a RX$ (on the rx$) and fill in your serial info for the device. Save the module in your USER DATABASE and your done.
