I have an Interlogix NX-6V2 and would like to add both the NX-595E (Ethernet) and the NX-584E (RS-232 serial) module to the same system. Both connect to the Com and Data bus terminals, can both modules be used at the same time or is it limited to only one? This is not going to be monitored by an alarm company. This is just for Home Automation (HA); the RS-232 is used by the HA system and the Ethernet will be used for time sync in the beginning and possibly more down the road.
Thank you in advance for assisting in this question.
