UIM2501 Converting Controller
M25020101008EN UI Robot Technology Co. LTD
OVERVIEW
1.0 OVERVIEW
UIM2501 RS232-CAN Converting Controller is used in conjunction with UIM242 stepper
motor controller to provide a RS232 interface on the user side and a CAN bus interface on
the motor controller side.
UIM2501 Controller’s functions can be summarized as:
1. Receives RS232 based instructions from user device, converts the instructions into
more concise and efficient CAN based instructions, and sends instructions to UIM242
controllers.
2. Converts CAN messages from UIM242 controllers into RS232 messages, and send
back to the user devices.
3. Coordinates and controls UIM242 controllers in the network.
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 supports 1Mbps CAN communication
speed. After optimization, all UIM242 instructions take less than 0.1 ms (normally 0.05 ms)
to transfer on the bus. On the user side, UIM2501 supports 115200 bps RS232 baud rate.
UI Robot provides free Microsoft Windows XP bases VB / VC demo software and their
source code to facilitate the quick start of user device side programming.
1.1 Instruction and Feedback Structure
As a protocol converter, UIM2501supports all instructions and conform to all instruction and
feedback structures of UIM242XX. Therefore, this information is omitted in this manual.
User can refer to the UIM242XX User Manual for details.
1.2 Motor Control Functions and Instructions
Motor control specific functions, instructions and operations are directly performed by the
UIM242 controllers. As a RS232-CAN converter, UIM2501 accepts all the instructions
described in the UIM242XX User Manual. User can refer to the UIM242XX User Manual for
detailed information.
