The UIM2502 RS232-CAN photoelectric isolation control gateway is used in conjunction with UIM242XX stepping motor motion controller. With UIM2502, user will be benefited from the advantages of the CAN network and the simplicity of RS232 protocol, and no need to deal with the complicated CAN protocol. With one UIM2502 you can control maximum100 units of UIM242XX through your upper computer. The instruction structure is simple, high fault tolerance. It can be operated by users who know nothing about motor drive or CAN. The enclosure is made of die-cast aluminum which provides a rugged, durable protection and improves the heat dissipation.
