Synchronize cDAQ-9174 with PXIe-1082?

Hi,

 

I have a cDAQ-9174 using a ni-9401 module to read position of an angular encoder. I have a PXIe-1082 chassis with PXIe-6365 Multifunction I/O module reading other analog inputs. I want to synchronize these two chassis but I'm not sure what hardware I need to make this happen. The 1082 backplane has BNC connections for 10MHz ref clock. It seems like I need an NI-9469 for the cDAQ with CAT5 cables, but it only  connects to other NI-9469 modules. I understand a cDAQ-9178 would have BNC connections on the chassis but is there a workaround for a cDAQ-9174?

 

This is an attempted solution to an issue I've been having the angular encoder being on the PXIe-6365 module. If the encoder is connected to the PXIe and powered on, the other signals on the module become extremely noisy, such that the data is unusable. So I disconnected the encoder from the PXIe and connected it to a cDAQ-9174, the only other daq device I have. This dramatically reduced noise in the other signals, however the data is no longer synchronized.

 

Thanks in advance!
