ICP DAS tM-7530 产品说明书

Quick Start fortM-7530Sep 2014, Version 1.0.0ICP DAS has provided a lot of UART/CAN product solutions which are widely recommended in the market. These UART/CAN converters can help users to implement the communication between RS-232 and CAN network. In order to cater for costing requirement, we provide a new solution of RS-232/CAN converter, tM-7530. The tM-7530 is a tiny RS-232/CAN to fit narrower environment as a result of its small size. It has isolation on power side and on CAN bus side and its performance is faster than other RS-232/CAN module. provides new function such as listen only. User can use this function to listen CAN bus messages and error detection. According to above features, tM-7530is an economical and practical RS-232/CAN converter solution.tM-7530 User ManualCD:\ fieldbus_cd\can\pac\ converter\ tM-7530\ manual\/pub/cd/fieldbus_cd/can/converter/tM-7530/manual\ tM-7530 Website/root/product/solutions/industrial_communication/fieldbus/cantM-7530 Utility/pub/cd/fieldbus_cd/can/converter/tM-7530/utilityICP DAS Website/1 -----------------------------------------------------------------------------------Hardware Introduction and InstallationThe left graph is the surface of tM-7530. It uses D-sub9 pin female connector as RS-232 communicationinterface and uses 2 or 3 wire to connect CAN buswith spring type connector. It has 2 LED indicatorsRun and Err. They are used to response modulestatus immediately at all time.Table: RS-232 Pin Assignment Table: Power and CAN Bus Pin AssignmentHow to connect with spring type connector? Press and Insert.2-----------------------------------------------------Configuration/Run ModeThere is a dip-switch on the bottom of tM-7530. After switching and rebooting, the tM-7530 will enter into Normal mode or Init mode.3-----------------------------------------------------tM-7530 wire connection4--------------------------------------Terminal Resistor5------------------------------------------------------------Software Utility IntroductionThere is no terminator resistor in the tM-7530. Therefore, if users would like to use terminator resistor, it is necessary to wire a 120Ω resistance on the CAN bus, as following figure.The tM-7530 uses VxCAN Utility to configure module and test. The VxCAN Utility is based on the Virtual CAN technology which is developed by the ICP DAS and is used to integrate the CAN interfaces of the different CAN converters from the ICP DAS. All of the CAN interfaces found by the PC will be sequentially mapping to the virtual CAN ports by the Virtual CAN driver. Users just use the virtual CAN ports to develop their application, and don ’t need to know what kind of6----------------------------------------------------------------------------Configure tM-7530 via VxCAN UtiliyBefore powering on the CAN converters, users must set them to the Init mode. Users need to switch the Init/Normal DIP-Switch to Init positionStep 3: Click the buttonThe configuration is divided to three areas with different color. They are UART, Communication, and CAN configuration area. Each area can set different parameters of tM-7530.After finishing the configuration, users can click the button “Save All Setting” to save the configuration in to the EEPROM of the CAN converter. If users would like to recover the parameters to the factory default, click “Load Default Setting” button to recover all of the configuration parameters to be default value. Afterwards, users can use the button “Save All Settings”to save the default parameters in to the EEPROM of the CAN converter.The default values of the parameters of the CAN converter are shown below.RS-232:RS-232 Baud rate = 115200Data Bit = 8Stop Bit = 1Parity = NoneAdd Checksum = NoError Response = NoTimeStamp Response = NoCAN:CAN Specification = 2.0ACAN bus Baud rate = 125KAcceptance Code = 000Acceptance Mask = 000Communication:7----------------------------------------------------------------Test tM-7530 via VxCAN UtiliySet the Init/Normal DIP switch of the CAN converter to normal mode. When the CAN module runs on the normal mode, the run LED indicator will be turned on. If the CAN converter sends or receives the CAN messages, the run LED will flash once per message.Step 3: Click the search buttonCheck the “Active Port ” and Click “Confirm ” button to enable the CAN port of the CAN converter. The parameters set here are not stored in the EEPROM. If users would like to configure the other parameters expect the CAN parameters, please use Configuration interface of the VxCAN Utility to do that.buttonThe test interface is divided to two areas. One is for sending CAN messages, and the other is for reception. If users want to send CAN message, fill the data into the corresponding field, and click “Send ” button. If the CAN converter gets any CAN messages, they will be shown in received area automatically. About the details for the VxCAN Utility operation please refer to the users ’ manual of the VxCAN Utility in the following web site.。
