E5@C Digital Temperature Controllers Communications Manual (H175)
When the host transmits a command frame, the E5@C transmits a response frame that corresponds to
the command frame. A single response frame is returned for each command frame. The following dia-
gram shows the operation of the command and response frames.
Communications with the host are carried out through a standard RS-485 interface. Use a K3SC Inter-
face Converter for RS-485 interface conversion.
