【 Weak current College 】 serial communication server FAQ-Power By 【 China power house network 】

Through the network set up and maintain IO-Server, you may encounter in
1. use the [upgrade] cannot search to IO-Server
Solutions
* Check whether the normal power IO-Server: observation panel Power or Ready lamp lit up
◆ Check IO-Server of ports on the line is even better: observation Panel link light is on, the observation of the connect IO-Server SWICH corresponding port HUB or led light
◆ Check your PC network connection: PC is able to communicate with other nodes
◆ Check your PC is running a firewall software, if any, may suspend the operation
2. use the [upgrade] program search to IO-Server, you cannot modify the IP temporarily IO-Server
Solutions
◆ Check your PC is running a firewall software, if any, may suspend the operation
3. use the [upgrade] program search to IO-Server, you cannot download firmware, prompting [connectdeviceerror]
Solutions
◆ From discovered IO-Server information view it in the IP address of your PC in the same network segment, if not, please use the [tools] [temporarychangeIPaddress], the IP address of the IO-Server temporary modifications to your PC in the same segment of IP
◆ Check your PC is running a firewall software, if any, may suspend the operation
4. use the [upgrade] program search to IO-Server, you cannot download firmware, prompting [Filedoesnotexist!]
◆ The program file in the shorter path directory, and the intermediate directory do not contain Chinese directory
◆ Verify that file exists

Console issues
1. terminal screen does not have any information
Solutions
◆ Check terminal of serial communication parameters, set aside rate 9600; bit 1; parity none; data flow control: none
¡Ô check cable is connected properly. General product that comes with RJ45 cable-DB-hole. Console DSR needs to be reset. If you do, please refer to the quick installation guide
◆ Terminal serial block. Close the terminal emulator, and then rerun
2. the terminal screen displays garbled
Solutions
◆ Check terminal of serial communication parameters, set aside rate 9600; bit 1; parity none; no data flow control
◆ Check the terminal emulation type is a VT100 or ANSI
3. If you forget the password IO-Server
◆ In IO-Server normal power, press and hold the RESET button next to the network I stay longer than 3 seconds, and then release, the password will be temporary elimination
◆ Use [HyperTerminal], through the CONSOLE into the settings, in the password prompt, type: Canhigh1234

Realport mode problem
1, serial program cannot open the serial port
Solutions
◆ Confirm network open
◆ Confirm [Control Panel] [COMportoverTCP/IP] set [DeviceIPaddress] and actual IO-Server IP are the same; confirm whether [DevicePort] IO-Server port corresponds to a consistent
◆ Check IO-Server [mode] is a [TCPrealport], [detail parameter] [authentication] is [none]
◆ Verify that your PC's operating system there are no other programs use this COM port
◆ Verify that no other PC with the appropriate ports have IO-Server connections: enter IO-Server [statistics] view [activity TCP information]
TCP/UDPSocket mode problem
1, as [TCPServer], cannot be connected
Solutions
◆ Verify that no other PC with the appropriate ports have IO-Server connections: enter IO-Server [statistics] view [activity TCP information]
◆ [Detail parameter] [authentication] is [none]
2, as [TCPClient] is unable to establish connection
Solutions
• Check whether you want to connect to the right of the TCPServer response connection: you can run the WINDOWS telnet + ip + tcpport way detection
◆ Check detailed parameters [initiated connection], look at the current situation meets the conditions for initiating the connection. Refer to the instruction manual of the TCP/UDPSocket mode "section

PPP mode problem
1, PPP can not be connected
Solutions
◆ Enter IO-Server settings, open the [statistics] [serial], observationof DCD status is ' 1 ' (i.e. IO-Server serial DCD signal is a ' high ', ' 1 ', IO-Server will not start PPP
◆ Check the client and service side the certificate matches a consistent way, and establish user name and password match a consistent
2, IO-Server as dial-up servers that can accept a client connection requests and establish the connection, but the client's PC can not be the same IO-Server inThe same LAN PC communication
Solutions
◆ The client's PC if network connection is working, and the network adapter's IP address on the LAN PC on the same network segment
◆ IO-Server [PPPdaemon] [detail parameter] [local IP address] and [local subnet mask] settings are not appropriate
3, IO-Server as dial-up server, the connection has been properly established, but the client's PC with IE open complex Web pages or downloading large files, often open or download incomplete, or even failure
Solutions
◆ Check IO-Server settings [serial], [control] and flow control for MODEM. Usually the flow control for MODEM rts/cts (hardware flow control)
¡Ô consultation between MODEM DCE rate is too low, then dial-up
4, IO-Server as dial-up server, the connection has been properly established, but the client's PC with IE in the address column, enter the domain name to open a Web page, you cannot open; in the enter the IP address the address column, you can open the
Solutions
◆ IO-Server [PPPdaemon] [detail parameter] [assigned DNS Server] is ' Yes '; in the [Server] set the DNS is a real and effective

Connection problems when character Terminal
To use terminal connection to the printer to print less content, content a lot will stop or garbled
Solutions
◆ IO-Server [serial] [data traffic control] and character terminal of flow control. Usually the domestic use of character terminal of flow control is the XON/XOFF ' "'
