1. Introduction “Embedded Internet” and “Embedded Et hernet” are hot topics today. Nowadays the Ethernet prot ocol becomes the de-fact o standard for local area network. Via Internet, connectivity is o ccurring everywhere, from home appliances to vending machines to testing equipm ent to UPS…etc.
The main features and specificati on of this are described as below: 1.1 Features z RDC 80186-80 Embedded CPU, or compatible z Ethernet Protocol, TCP,UDP , IP, ICMP, ARP, HTTP z Reloadable Oper ating .
1.2 Specifications CPU CPU 80186, 80MHz or compatible SRAM 512K Bytes Flash 512K Bytes EEPROM 16K Bytes NVRAM 31 Bytes (battery backup, data valid up to 10 year) RTC (Real Time Clock ) Yes 64-bit Hard.
i-7540D Software Utility tool: z CAN bus Baud Rate configuration; z CAN acceptance filt er configuration; z CAN 2.0A or 2.0B specific selection; z Setting the IP, Gateway and Ma sk of the network status; z Setting the Web ID and password z RS-232/RS-485 baud rate and data bit setting; z CAN bus pair connection par ameters configuration.
1.3 VxComm Technology The i-7540D is designed as a RS-232/RS-485/CAN to Et hernet Gateway. So it follows that they can be used to link these RS-232/RS-485/CAN devices to central computer as follows: Figure 1-2: Application of i-7540D Compared to the RS-485 network, these Ethernet network hubs are already in existence for system network.
In some factories, there are old syst ems still running and in case. These old systems only support COM port applications . Therefore, the Vxcomm technology can be used to upgrade these old syst ems to support Ethernet network. To recap, the VxComm technology is useful as follows: z Provides a much easier interface for software programmers.
2. Hardware 2.1 Block Diagram Figure 2-1 is a block diagram illustrating the functions on the i-7540D module . It provides the 2500Vrms Isolation in the CAN interface site.

2.2.1 RS-232 & RS-485 & Power supply Interface The I-7540D provides one RS-232 interf ace and one RS-485 interface with hardware flow control. The GND-signal of COM1 is shar ed with pin-9, GND.
2.2.2 Connect to CAN Bus In order to provide an easy CAN bus wiring, the i-7540 D supplies one CAN port with two CAN bus connector interfaces . Each connecter built on the i-7540D looks like as figure 2-3 and table 2-2. Table 2-2: CAN bus Connector Pin Assignment Pin No.
2.2.3 Ethernet Connect The Ethernet (10/100 Base-T X) signals are routed to an RJ45 socket for easy connection using a standard CAT 3 or CAT 5 network cable.
2.3 Terminator resistor settings In order to minimize refl ection effects on the CAN bus line, the CAN bus lines have to be terminated at both ends by two terminal resistances. Based on the ISO 11898-2 spec, each terminal resistance is 120 Ω (or between 108 Ω ~132 Ω ).
Therefore, the i-7540D m odule supplies a jumper for users to connect the terminator resistor or not. If users want to use this terminator resistor, please open the i-7540D cover and use the JP3 jumper to activate the 120 Ω terminator resistor built in the system, as in the fi gure 2-5.

2.4.2 CAN bus indicator LED The i-7540D includes three single-color LED displays to indicate the status of module, network and I/O device. They are ER LED (it is red), TX LED (it is green), and RX LED (it is red). The Indicators assist maintenance personnel in quickly identifying a problem unit.
z RX LED This LED indicates the status of message received. Table 2-8 shows t he conditions for RX status. Therefore, when the device receives CAN messages, the RX-LED would be flashed.
2.4.3 5-digits 7-Segment LED Displays The 5-digits 7-SEG LED will show as figure 2-6. Figure 2-6 7-SEG LED Displays The important information of i-7540D can be divided as follows: z Group-ID 11111: IP.
z LED-2~5: IP The LED will show Group-ID first, and then show its IP as the above diagram indicates. If users change IP, the val ue shown will change immediately. The default shipping IP = 192.168.255.1 Î the LED-show sequence is given as above diagram.
The configuration of CAN port is given as follows: z LED-1: CAN port number z LED-2~5: CAN specification (2.0A or 2.0B) The connection-client and CAN bus pair connection information are given as follows: z Group-ID of 5-digit LED: 44444. z LED-1: indicator, can be 0 or 1 or 2 or 3 or 4 or 5.

5. VxComm Applications z Overview z Installing the VxComm Driver z Adding a i-7540D and confi guring the VxComm Driver z Removing a i-7540D z Uninstalling the VxComm Driver 5.1 Overview The VxComm (Virtual Comm) D river and VxComm Utility are very easy to install and use.
5.1.1 Architecture The VxComm Driver creates COM port(s) and maps them to the COM port(s) of the i-7540D . The user's RS-232 client pr ograms need only to change to the different COM port to access the serial devices that are allocated to the Internet or Ethernet network via the i-7540D .
5.1.2 Ports mapping Vxcomm Driver/Utility supports Port 1 to Port 3 in accessing COM1 to COM3 of the i-7540D. Another Port I/O is des igned to access the I/ O boards mounted on i-7540D, but it doesn’t use now . With the help of the VxComm Driver/Utility, uses can map remote COM port to become a virtual COM port of PC.
5.2 Installing the VxComm Driver Step 1: The installation software can be obtained from the following location. z http://ftp.icpdas.com/pub/cd/8000cd/napdos/7188e/tcp/vxcomm/ driver(pc)/ z 8000cd:Napdos7188eTCP vxcommdriver(pc) Please choose the version that suits your Windows operation system.
Step 3: Select the “ Yes , …” option and click the Finish button to restart your computer. Step 4: After rebooting the computer , the VxComm Utility will ask you to configure the virtual COM port(s). Please refer to the next section (5.3) for more information.
5.3 Adding an i-7540D and conf iguring the VxComm Driver Step 1: Obtain the IP addre ss of the i7540D. The MiniOS7 Utility can help you in obtaining the IP address of the i-7540D. Note : The default IP address of the i-7540D is 192.168.255.1 Step 2: From the Winsows Start Menu, go to Program/7188e/Vxcomm2K/ and locate the VxComm Utility.
Note: z Check Duplicated IP option This option checks whether the IP addres s is already listed in the server window (left hand window). It is automatically checked by default.
Step 4: And then it will display the name of “ 7186E3 ” and it’s IP. Select one of the i-7540D devices and configure the vi rtual COM port(s) by double clicking " Port 1 ", " Port 2 " or “ Port 3 ”. Step 5: Select an appropriate COM por t number, and then click the OK button.
Step 6: Select one of the i- 7540D modules, and then click the Server Options button to configure the server options. Step 7: Enter the new c onfiguration settings. The new settings will replace any text already in the Server Opti ons window text boxes.
layer may respond with a “Disconnect” event to the VxComm Driver if it fails to send the message after 20 seconds or more. Users can set a smaller Connection-Broken time (for example: 10000 ms ) to force the VxComm Driver to re-connect again and get a quicker response.
Step 8: Click the Exit button to exit the Vx Comm Utility. Before exiting, the Re-starting the Driver dialog window will automatically display. Click the Re-start button to stop/st art the driver. i-7540D CAN-Ethernet Gateway Use r’s Manual (Version 1.
