Description
The UIM2501 RS232-CAN Converting Controller is used in conjunction with UIM242XX stepper
motor controller to provide a RS232 interface on the user side and a CAN bus interface on the
motor side (factory side).
With the UIM2501, 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, no worry
about the communication distance and noise immunity.
One UIM2501 controller can network with up to 100 UIM242XX controllers. Interfacing the
UIM2501 is simple, intuitive and fault tolerating. Users are not required to have stepper motor
driving or CAN protocol knowledge.
UIM2501 is compact in size. The enclosure is made of die-cast aluminum to provide a rugged
durable protection and improves the heat dissipation.
