I have a situation where a dealer who is having issues with getting 15 CC-16s to work together in a semi star configuration.
The installation is a existing one where they are replacing another company’s remote devices. The existing devices were wired with Cat5 wiring each home run to the main rack.
He has connected them in groups of five to a terminal strip and then jumpered them together to send a single line up to the RS485 connection on the ESP.
He has used a ground connection to all of the devices and has the two longest lines terminated and all the rest unterminated.
The two issues he is having is that three of the devices are not communicating with the processor and that the response of some of the selector settings are "sluggish" in their response.
Any suggestions. This is not new construction so running new cable is probably not an option.
