Can it operate as time code and GPS receiver simultaneously?
Yes. The XLi system, through any of its three interfaces, can be programmed to assign the GPS receiver and the Code In input to either primary or secondary reference source. Of course, only one of them will be primary and the other will be the secondary reference source. When the XLi system is using the Code In input as primary reference source, it can function as a TCU to either generate codes or synchronized to input codes as a SyncGen.
