NPort W2004 User’s Manual Web Console Configuration Time Settings NPort W2004 has a built-in Real-Time Clock that allows you to add real-time information to functions such as Auto warning “Email” or “SNMP Trap.” ATTENTION First time users should select the time zone first. The Console will display the “real time” according to the time zone compared to GMT. If you would like to modify the real time clock, select “Local time.” NPort W2004’s firmware will modify the GMT time according to the Time Zone.
NPort W2004 User’s Manual Time server Setting IP Address or Domain Name (E.g., 192.168.1.1, time.stdtime.gov.tw, or time.nist.gov) Web Console Configuration Factory Default Necessity None Optional NPort W2004 uses SNTP (RFC-1769) for auto time calibration. Input the correct “Time server” IP address or domain name. Once NPort W2004 is configured with the correct Time server address, NPort W2004 will request time information from the “Time server” every 10 minutes.
NPort W2004 User’s Manual Web Console Configuration In order to use NPort W2004’s DNS feature, you need to configure the DNS server. Doing so allows NPort W2004 to use a host’s domain name to access the host. NPort W2004 provides DNS server 1 and DNS server 2 configuration items to configure the IP address of the DNS server. DNS Server 2 is included for use when DNS sever 1 is unavailable.
NPort W2004 User’s Manual Web Console Configuration A netmask is used to group network hosts into subnets. When a packet is sent out over the network, the NPort W2004 will use the netmask to check whether the desired TCP/IP host specified in the packet is on the same subnet as the NPort. If the address is on the same subnet, a connection is established directly between the NPort W2004 and the host. If the host is not on the same subnet, the packet is sent to the Gateway address. Gateway Setting E.g., 192.
NPort W2004 User’s Manual Web Console Configuration interface. For detailed information about configuring IP configuration, IP address, Netmask, and Gateway, see the previous section, “Ethernet Configuration.” Wireless LAN You may choose from two different WLAN modes—Infrastructure Mode and Ad-hoc Mode— which are illustrated in the following diagrams.
NPort W2004 User’s Manual Web Console Configuration SSID Enter the name of the wireless network (SSID) that the W2004 is connected to. Channel Select a radio channel for the wireless network from the pull-down menu. In infrastructure mode, the AP will specify the channel automatically. In Ad-hoc mode, the user must use the pull-down menu to specify the channel. ATTENTION Click on the Wizard to configure the WLAN IP address quickly.
NPort W2004 User’s Manual Web Console Configuration Serial Port Settings Serial port settings are configured by port. Operation Modes The Serial Port parameters that appear in the right pane of the browser window when Serial Port Settings # Port 1/2/3/4 # Operation Modes is selected are dependent on which of the four operation modes is selected. We consider each operation mode separately.
NPort W2004 User’s Manual Web Console Configuration ATTENTION When Max connection is set to 2, 3, or 4, NPort W2004 will use a “multi connection application” (i.e., 2, 3, or 4 hosts are allowed access to the port at the same time). When using a multi connection application, NPort W2004 will use the serial communication parameters set in the console. All of the hosts connected to that port must use the same serial settings.
NPort W2004 User’s Manual Web Console Configuration than or equal to 10 ms. If you want to send a series of characters in the same packet, the serial device attached to NPort W2004 should send that series of characters during a time interval less than the Force transmit timeout, and the total length of data must be less than or equal to NPort W2004’s internal buffer size. The serial communication buffer size for NPort W2004 is 1 KB per port.
NPort W2004 User’s Manual Web Console Configuration ATTENTION The Inactivity time should be set at least larger than that of Force transmit timeout. To prevent the unintended loss of data due to the session being disconnected, it is highly recommended that this value is set large enough so that the intended data transfer can be completed.
NPort W2004 User’s Manual Web Console Configuration ATTENTION Delimiter 2 is optional. If left blank, then Delimiter 1 alone trips clearing of the buffer. If the size of the serial data received is greater than 1 KB, the NPort W2004 will automatically pack the data and send it to the Ethernet. However, to use the delimiter function, you must at least enable Delimiter 1. If Delimiter 1 is left blank and Delimiter 2 is enabled, the delimiter function will not work properly.
NPort W2004 User’s Manual Command port Setting 1 to 65535 Web Console Configuration Factory Default Necessity 966 Optional The “Command port” is a listen TCP port for IP-Serial Lib commands from the host. In order to prevent a TCP port conflict with other applications, the user can set the Command port to another port if needed. IP-Serial Lib will automatically check the Command Port on NPort W2004 so that the user does not need to configure the program.
NPort W2004 User’s Manual Web Console Configuration 0-65535 ms: NPort W2004 automatically closes the TCP connection if there is no serial data activity for the given time. After the connection is closed, NPort W2004 starts listening for another host’s TCP connection. This parameter defines the maintenance status as Closed or Listen for the TCP connection. The connection is closed if there is no incoming or outgoing data through the serial port during the specific Inactivity time.
NPort W2004 User’s Manual Force transmit Setting 0 to 65535 ms 0: Disable force transmit timeout. Web Console Configuration Factory Default Necessity 0 Optional 1 to 65535: Forces the NPort W2004’s TCP/IP protocol software to try to pack serial data received during the specified time into the same data frame. This parameter defines the time interval during which NPort W2004 fetches the serial data from its internal buffer.
NPort W2004 User’s Manual Web Console Configuration UDP Mode Data Packing Delimiter 1/2 Setting 00 to FF (hex) Factory Default Necessity None Optional Once the NPort W2004 receives both delimiters through its serial port, it immediately packs all data currently in its buffer and sends it to the NPort W2004’s Ethernet port. ATTENTION Delimiter 2 is optional. If left blank, then Delimiter 1 alone trips clearing of the buffer.
NPort W2004 User’s Manual Web Console Configuration during the specified time into the same data frame. This parameter defines the time interval during which NPort W2004 fetches the serial data from its internal buffer. If data is incoming through the serial port, NPort W2004 stores the data in the internal buffer.
NPort W2004 User’s Manual Web Console Configuration Port 1/2/3/4 Port alias Setting Factory Default Necessity 1 to 15 characters None Optional (e.g., PLC-No. 1) “Port alias” is included to allow easy identification of the serial devices that are connected to NPort W2004’s serial port. Serial Parameters ATTENTION Check the serial communication parameters in your Serial Device’s user’s manual.
NPort W2004 User’s Manual Web Console Configuration Data Bits Setting Factory Default Necessity 5, 6, 7, 8 8 Required When the user sets Data bits to 5 bits, the Stop bits setting will automatically change to 1.5 bits. Stop Bits Setting Factory Default 1, 1.5, 2 1 Stop bits will be set to 1.5 when Data bits is set to 5 bits.
