Serial Ports on Axcent3 and NI
Can someone please explain the difference between a serial port on an Axcent 3 and an NI controller? I integrated a DSC Maxsys security system into a project, initially assigned to an Axcent3 but it didn’t work. However when I reassigned the Maxsys to a serial port on the NI it worked perfectly. I swapped ports with a receiver and now both devices work, so I know it’s not a bad port. Only differences are baud rates (2400 on Maxsys, 9600 on receiver) and use of RTS connection on pin 7 for Maxsys. AMX Engineering please feel free to chime in.
