I use this The CDM-VW305 - 8channel interface between sensors(vibrating-wire sensors) and dataloggers CR6. I have two CDMs devices connected in series on thise datalogger. On the last device is CPI terminator. Everything was good. I sent the new program to the remote datalogger CR6 and one CDM device does not reply. In CPI Status (data monitorin) in Device Configuration Utility does not display this module. And all vibrating-wir sensors in thise CDM show value NAN. How can I solve this problem on a remote dataloger, CDM?
