The CPT-DFC4 is a Communications Peripheral card within the DF Series Range. The card contains an isolated RS422/RS485 interface, isolated CAN interface and an isolated Serial Peripheral interface (isoSPI format).
The card's isolated outputs are all powered via the DF Series Communications Interface. The CPT-DFC4 has switches on-card for selection of the active SCI and CAN ports. RS422 or RS485 can be selected via an on-card switch. The SPI interface can be selected for Master or Slave mode and the SPI MODE (0-3) is also configurable via on-card switches. These selections must match the software programmed by the user within the DF Series Control Card that forms part of the stack.
The CPT-DFC4 card mounts within the DF Series stack and uses the 26 way Communications Interface for communication with the DF Series Control Card.
