High noise immunity due to differential bus implementation RS232 Communication: .. RS232 three-wire serial communication .. Max baud rate 112500 bps .. Automatic Baud Rate Detection Wide supply voltage: Wide supply voltage range 6 ~ 40VDC Description The CI250 CAN-RS232 converting controller is used in conjunction with CI 242xx stepper motor controller to provide a RS232 interface on the user side and a CAN bus interface on the motor side (factory side). By using the CI 250 controller, users can be benefited from the advantages of CAN base control network without dealing with the complicated CAN protocol. User only needs to communicate with the CI 250 controller using the simple, intuitive and ASCII coded RS232 instructions. All CAN bus issues are taken care of by the CI 250 converting controller. Both the CI 250 controller and the UIM242xx controller support network. One CI 250 controller can command up to 100 CI 242xx controllers. Interfacing the CI 250 is simple, intuitive and fault tolerating. Users are not required to have stepper motor driving or CAN protocol knowledge. CAN-RS232 Converting Controller CI25001

CI25001 converter has a build-in terminating resistor. User only needs to attach a resistor at the other end of the bus. To enable the CI25001 converter’s terminating resistor, see the CI25001 manual. To achieve the best communication performance, CANH and CANL should use a twisted pair Network Operation : Multiple CI242xx controllers can be wired together to form a reliable...
