ATTENTION

Safety First!

Be sure to disconnect the power cord before installing and/or wiring your CN2600.

Wiring Caution!

Calculate the maximum possible current in each power wire and commo dictating the maximum current allowable for each wire size. If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your equipment.

Temperature Caution!

Be careful when handling the CN2600. When plugged in, the CN2600’s internal components generate heat, and consequently the board may feel hot to the touch.

NOTE

Do not run signal or communication wiring and power wiring in the same wire conduit. To avoid interference, wires with different signal

Desktop

Place your CN2600 on a clean, flat, well-ventilated desktop. For better ventilation, attach the 4 pads from the desktop kit to the bottom of the unit, and leave some space between the CN2600 and other equipment. Do not place equipment or objects on top of the unit, as this might damage the server.

Rackmount

The CN2600 is designed to be mounted on a standard 19-inch rack. Use the enclosed pair of L-shaped metal brackets and screws to fasten your CN2600 to the rack cabinet. Each L-shaped bracket has 6 holes, leaving two outer or inner holes available for other uses. You have two options. You can lock either the front or rear panel of the CN2600 to the front of the rack.

In some critical environments, you may need to add termination resistors to prevent the reflection of serial signals. When using termination resistors, it is important to set the pull high/low resistors correctly so that the electrical signal is not corrupted. The CN2600 uses jumper settings or DIP switches to set the pull high/low resistor values for each serial port.

To set the pull high/low resistors to 150 KΩ, make sure both of the assigned DIP switches are in the OFF

ATTENTION

Consult your network administrator on how to reserve a fixed IP address for your CN2 mapping table when using a DHCP Server or BOOTP Server. For most applications, you should assign a fixed IP address to your CN2600.

NOTE

The wide temperature model does not have an LCM Display panel and push buttons. The LCM description below applies only to standard temperature models.

Static and Dynamic IP Addresses

Determine whether your CN2600 needs to use a static IP or dynamic IP address (either DHCP or BOOTP/PPPoE application).

• If your CN2600 terminal server is used in a static IP environment, you will assign a specific IP address using one of the tools described in this chapter.

• If your CN2600 terminal server is used in a dynamic IP environment, the IP address will be assigned automatically from over the network. In this case, set the IP configuration mode to DHCP, DHCP/BOOTP, BOOTP, or PPPoE.

Factory Default IP Address

The CN2600 is configured with the following default private IP addresses:

192.168.126.254 and 192.168.127.254

Note that IP addresses that begin with “192.168” are referred to as private IP addresses. Devices configured with a private IP address are not directly accessible from a public network. For example, you would not be able to ping a device with a private IP address from an outside Internet connection. If your application requires sending data over a public network, such as the Internet, your CN2600 will need a valid public IP address, which can be leased from a local ISP.

4. Serial Port Operation Modes

In this chapter, we describe the various operation modes of the CN2600. CN2600 modes are grouped by type of application, such as Device Control or Reverse Terminal. The options include an operation mode that relies on a driver installed on the host computer, and operation modes that rely on TCP/IP socket programming concepts. After selecting the pr oper operation mode, please refer to C h apter 5, Configuration with the Web Console, for detailed information on configuration parameters.

The following topics are covered in this chapter:

CN2600 Series Serial Port Operation Modes

The CN2600 comes bundled with Real COM drivers for Windows 98/ME/NT/ 2000/XP/2003/Vista systems and TTY drivers for Linux systems. In Real COM mode, the bundled drivers are able to establish a transparent connection between a host and a serial device by mapping the serial port on the CN2600 to a local COM/TTY port on the host computer. Real COM mode supports up to 8 simultaneous connections that enable multiple hosts to simultaneo

Overview

The CN2600 network-enables traditional serial (RS-232/422/485) devices. The serial device server is a special-purpose computer equipped with a CPU and TCP/IP protocols that can bi-directionally translate data between the serial and Ethernet for ma ts. Your own computer will be able to ac cess, manage, and configure remote facilities and equipment over the Internet from anywhere in the world.

Traditional SCADA and data collection systems rely on serial ports to collect data from various kinds of instruments. Since the C N2600 network-enables instruments equipped with an RS-232, RS-422, or RS-485 communication port, your SCADA and data collection system will be able to access all instruments connected to a standard TCP/IP network, regar d less of whether the devices are used locally or at a remote site.

The CN2600 is an external IP-based network device that allows you to expand the number of serial ports for a host computer on demand. As long as your host computer supports the TCP/IP protocol, you will not be limited by the host computer’s bus limitation (such as ISA or PCI), nor will you be limited by the absence of drivers for various operating systems.

In addition to providing socket access, the CN2600 also comes with a Real COM/TTY driver that transmits all serial signals intact. This enables you to preserve your existing COM/TTY-based software without needing to invest in additional software.

Three different socket modes are ava ilable: TCP Server, TCP Client, and U DP Server/Client. The main difference between the TCP and UDP protocols is that TCP guarantees delivery of data by requiring the recipient to send an acknowledgement to the sender. UDP does not require this type of verification, making it possible to offer faster delivery. UDP also allows unicast or multi-unicast of data to one IP or groups of IP addresses.

The CN2600 also supports console mana gement applications, includin g Rev erse Telnet modes. Reverse terminal modes enable you to connect to a server’s console port through an IP network for remote control and/or monitoring of that server.

Device Control Applications

For device control applications, the CN2600 offers the following modes: Real COM and RFC2217 mode.

Real COM Mode

usly collect data from the same serial device.

One of the major conveniences of using Real COM mode is that it allows you to use software that was written for pure serial communication app lications. The Real COM driver inter cepts data sent to the host’s COM port, packs it into a TCP/IP packet, then redirects it through the host’s Ethernet card. At the other end of the connection, the CN2600 accepts the Ethernet frame, unpacks the TCP/IP packet, and then transparently sends the data through the serial port to the attached serial device.

CN2600 Series Serial Port Operation Modes

4-3

ATTENTION

Real COM mode allows several hosts to have access control over the same CN2600. The drivers that come with your CN2600 control host access by checking the host’s IP address. Please refer to the Accessible IP List section in Chapter 8,

In TCP Server mode, the serial port on the CN2600 is assigned a port number which must not conflict with any other serial port on the CN2600. The host computer initiates contact with the CN2600, establishes the conn ection, and receives data from the serial device. This operation mode also supports up to 8 collect data from the same serial device at the same time. As illustrated in the figure, data tran smission proceeds as follows: The host requests a connection from th e CN2600, which is configured for TCP Once the connection is established, data can be transmitted in both directions between the host and the CN2600.

In TCP Client mode, the CN2600 can actively establish a TCP connection to a pre arrives. After the data has been transferred, the CN2600 can automatically disconnect from the host computer by using the Inactivity time settings. As illustrated in the figure, data tran smission proceeds as follows: The CN2600, configured for TCP connection from the host. Once the connection is established, data can be transmitted in both directions between the host and the CN2600.

System Management Set tings, for more details.

RFC2217 Mode

RFC-2217 mode is similar to Real C OM mode. That is, a driver is used to establish a transparent connection between a host computer and a serial device by mapping the serial port on the CN2600 to a local COM port on the host computer. RFC2217 defines general COM port control options based on the Telnet protocol. Third party drivers supporting RFC-2217 are widely available on the Internet and can be used to implement Virtual COM mapping to your CN2600 serial port(s).

Socket Applications

For socket applications, the CN2600 offers the following modes: TCP Server, TCP Client and UDP.

Redundant COM

The Redundant COM operation mode can be used to set up a redundant LAN between the serial devices connected to the CN2600’s serial po rts and the host computer. The redundant structure involves using the CN2600’s two LAN ports to set up two independent LANs that connect the CN2600 to the host computer. I f either of the two LANs fails, the other LAN will continue transmitting packets between the serial devices and the host, with the packets passing through the CN2600. In fact, one of the biggest advantages of the CN2600’s Redundant COM mode is that the “switching time” is zero.

Dual-host Redundant Data Acquisition System (DRDAS)

The DRDAS operation mode provides a highly redundant network structure that takes advantage of the CN2600’s dual LAN ports, dual IP addresses, and dual MAC addresses. DRDAS uses a backup PC that is set up to take over when the primary PC fails.

The CN2600’s dual-host redundant configuration sends seria l data to 4 IP addresses on the network. U sers select a Primary IP and 3 Secondary IPs. When the Primar y IP fails, the backup IPs take over by using the DRDAS library.

The DRDAS library is used to configure the DRDAS of the CN series. You must use the DRDAS libr ar y to designate the primary and secondary hosts. If you need this library, please contact conn.support@moxa.com

With this kind of redundant setup, if one of the secondary IPs tries to send commands to the serial device, the commands are discarded by the CN2600, since only the Primary IP is allow ed to conduct bi-directional transmission. The backup IPs are only allowed to receive data from the CN2600.

Terminal Applications

Terminal applications involve connecting terminals to UNIX or Windows servers over a network. A terminal connects to the appropriately configured serial port the CN2600, and the CN2600 transmit s information to and from a UNIX or Windows server over the network through its Ethernet port. You may need to check with your network administrator to determine the appropriate terminal mode. All terminal modes support fast keys as used in many terminal a pplications.

Please refer to Chapter 4, Introducing Serial Port Operation Modes, for detailed information and configuration instructions.

Terminal ASCII Mode

Terminal ASCII mode can handle up to 8 sessions per port with the ability to sw itch between sessions on the same terminal. This mode is used for text-based terminals with no file transfer capability or encryption.

Terminal BIN Mode

Terminal BIN mode allows one session per port and is used for terminal applications that include fil e transfer features.

CN2600 Series Serial Port Operation Modes

Reverse Terminal Applications

Reverse terminal applications a re similar to terminal applications i n that they involve using the CN2600 to manage the connection between a term inal and a server. The difference i s that with reverse terminal applications, the terminal is connected through the network and the server is connected through the serial port, rather than the other way around. In practice, a reverse terminal session typically involves a network administrator telnetting to a device that has a dedicated serial console port used specifically for configuration purposes.

For example, many routers, switches, UPS units, and other devices (including the CN2600) have Console/AUX or COM ports to which a terminal can be physically connected for console management. With the CN2600, the device’s console port can be connected to a serial port on the CN2600, allowing a network administrator to telnet to the device remotely through the network. Although modern network equipment generally allows other options for remote configuration through the network, there are situations in which it is necessary or desirable to configure a device by serial console (e.g., for security reasons, when using older-generation equipment, or as a backup configuration method when the network is down).

CN2600 reverse terminal modes al lo w the use of the CN2600 User Table or a RADIUS server for identity verification purposes. Please refer to the Misc. Network Settings section in Chapter 8, System Management Settings, for instructions on setting up the CN2600 User Table.

Reverse Telnet

Reverse Telnet mode is widely used for device management in telecommunication control rooms. The system waits for a host on the network to initiate a connecti on. Since TCP Server mode does not assist with convers ion of CR/LF commands, reverse termina l applications that require this conversion should use Reverse Telnet mode.

Dial In/Out Modes

The CN2600 provides dial-in/dial-out access for ISPs and enterprises that need a remote access solution. When a user at a remote site uses a PPP dial-up connection to access the CN26 00, the CN2600 plays the role of a dial-up server, but also ensures that the user has legal access to the network b y verifying the user’s identity with the CN2600 User Table or a RADIUS server. Please refer to the Misc. Network Settings section in Chapter 8, System Management Settings, for instructions on setting up the CN2600 User Table.

The CN2600 supports PPP, SLIP, and Terminal modes for dial-in/dial-out access. Regardless of which operating system is used, you will always be able to use standard PPP dial-up to establish a connection. The CN2600 can also act as a router to connect serial ports to a WAN connection. Routing protocols (including static, RIP I, and RIP II) can be adjusted to route different WAN connections.

Please refer to Chapter 5, Configuration with Web Console, for detailed information and configuration instructions.

Network Settings

Basic Network Settings

You can access Basic Network Settings by expanding the Network Settings item in the navigation panel. Basic Network Settings is where you assign the CN2600’s IP address, netmask, Gateway, and other IP parameters.

NOTE: You must assign a valid IP address to your CN2600 before it will work in your network en vironment. Your network system administrator should provide you with a unique IP address and related settings for your network. First-time users can refer to Chapter 3, Initial IP Address Configuration, for more information.

ATTENTION

In dynamic IP environments, the firmware will try to get the network settings from the DHCP or BOOTP server 3 times every 30 seconds until network settings are assigned by the DHCP or BOOTP server. The first try times out after 1 second, the second after 3 seconds, and the third after 5 seconds. If the DHCP/BOOTP server is u netmask, and gateway settings.

IP configuration (default=Static): You can choose from four possible IP configuration modes.

IP Address (LAN1 default = 192.168.127.254; LAN2 default = 192. 168. 126. 254) : E n ter t h e IP address that will be assigned to your CN2600. All ports on the CN2600 will share this IP address. An IP address is a number assigned to a network device (such as a computer) as a permanent address on the network. Computers use the IP address to identify and talk to each other over the network. Choose a proper I P addre ss tha t is unique and valid in your network environment.

Netmask (default=255.255.255.0): Enter the subnet mask. A subnet mask represents all of the network hosts at one geographic location, in one building, or on the same local area network. When a packet is sent out over the network, the CN2600 will use the subnet mask to check whether the desired TCP/IP host specified in the packet is on the local network segment. If the address is on the same network segment as the CN2600, a connection is established directly from the CN2600. Otherwise, the connection is established through the given default gateway

Gateway: Enter the IP address of the gateway if applicable. A gateway is a network computer that acts as an entrance to another network. Usually, the computers that control traffic within the network or at the local Internet service provider are gateway nodes. The CN2600 needs to know the IP address of the default gateway computer in order to communicate with the hosts outside the local network environment. For correct gateway IP address information, consult the network administrator.

navailable, the firmware will use the default IP address (192.168.127.254),

DNS server 1: This is an optional field. If your network has access to a DNS server, you may enter the DNS server’s IP address in this field. This allows the CN2600 to use domain names instead of IP addresses to access hosts.

Domain Name System (DNS) is the way that Internet domain names are identified and translated into IP addresses. A domain name is an alphanumeric name, such as www.moxa.com, that it is usually easier to remember than the numeric IP address. A DNS server is a host that translates this kind of text-based domain name into the actual IP address used to establish a TCP/IP connection. When the user wants to visit a particular website, the user’s computer sends the domain name (e.g., www.moxa.com) to a DNS server to request that website’s numeric IP address. When the IP address is received from the DNS server, the user’s computer uses that information to connect to the website’s web server.

The CN2600 will play the role of a DNS client, in the sense that it will actively query the DNS server for the IP address associated with a particular domain name. The following functions on the CN2600 web console support the use of domain names in place of IP addresses: Time Server, Destination IP Address (in TCP Client mode), Mail Server, SNMP Trap Server, Destination Address (in Pair Connection mode), Primary/Secondary Host Address (in Terminal mode), RADIUS Server and SMTP Server.

DNS server 2: This is an optional field. The IP address of another DNS server may be entered in this field for times when DNS server 1 is unavailabl e.

PPPoE user account and PPPoE password: For dynamic broadband networks such as xDSL or cable modem,

users must enter the username and password that they received from their ISP to establish network connection. If a serial port on the CN2600 will be using PPPoE, enter the account name an d p a ssword in these fields.

WINS function (default=enable): Enable or disable the WINS (Windows Internet Naming Service) serv er. WINS server: If a WINS Server is connected to the network, enter the WINS Server’s IP address in this field.

TCP/IP uses IP addresses to identify hosts, but users often use symbolic names, such as computer names. The WINS Server, which uses NetBIOS over T C P/IP, contains a dynamic database to map computer names to IP addresses.

LAN speed (default=Auto): You may configure the network speed for the built-in Ethernet connection on the CN2600. IEEE802.3 Ethernet supports auto negotiation of transfer speed. However, some switches/hubs require that the communication speed be fixed at 100Mbps or 10Mbps.

Advanced Network Settings

You can access Advanced Network Settings by expanding the Network Settings item in the navigation panel. Advanced Network Settings is where the routing protocol and gratuitous ARP are configured.

What is RIP?

RIP (Routing Information Protocol) is a protocol used to manage routing information within a self-contained network, such as a corporate LAN (Local Area Network) or an interconnected group of such LANs.

By using RIP, a gateway host with a ro uter can send its entire routing table, which lists all the other hosts it knows about, to its closest neighbor host every 30 seconds. The neighbor host in turn will pass this information on to its closest neighbor, and so on, until all hosts within the ne twork have the same routing path information. This state is known as network convergence. RIP uses a hop count as a way of determining network distance. (Other protocols use more sophisticated algorithms that also include timing.) After receiving a packet headed for a specific destination, a network host with a router uses the routing table information to determine the next host to route the packet to.

RIP is considered an effective solution for small homogeneous networks. For larger, more complicated networks, transmitting the entire routing table every 30 seconds can bog down the network with a lot of extra traffic.

RIP 2 is an extension of RIP. Its purpose is to expand the amount of useful information contained in RIP packets, and to add security elements. RIP 2 has become the standard version of RIP, and the original RIP is no longer used.

Routing Protocol: You may select which routing protocol, if any, your network will employ. Gratuitous ARP: In some applications, you may n eed the CN2600 to send broadcast packets to update the

ARP table on the server. If you enable this function and set the send period, the CN2600 will send periodically send broadcast packets at the specified time interval.

Configuring the Route Table

You can access the Route Table by expanding System Management and then Misc. Network Settings in the navigation panel. The route table is where you configure how the CN2600 will connect to an outside network.

You are allowed up to 32 entries in the route table. For each entry, you must provide information on the gateway, destination, netmask, metric hops, and interface.

Gateway: This is the IP address of the next-hop router. Destination: This is the host ’s IP address or the network address of the route’s destination. Netmask: This is the destination network’ s netmask. Metric: Enter the number of hops from the source to the destinationto allow the CN2600 to prioritize the

routing of data packets if more than one router is available. Iface: This is the network interface to which the packet must be sent.

Configuring Routes to the Internet

In this example, the Notebook PC dia ls into the CN2600 to request a connection to the Internet host at

210.48.96.9, which is not on the local network 203.67.6.xxx. This causes the CN2600 to act as a router and send the datagram to the default next-hop router, 203.67.6.254. In this case, we should add the gateway IP address of 203.67.6.254 to the routing table to ha n dle hops to 210.48.96.9.

Generally, connections to the Internet are handled by assigning a gateway server in the network settings rather than through the route table.

In this example, dial-in users can make requests to Intranet hosts 202.65.66.4 or 202.65.66.5, which are on network 202.65.66.xxx (located outside network 203.67.6.xxx). You will need to add a route entry for the next-hop router, 203.67.6.252 that delivers requests to network 202.65.66.xxx. The metric hop in this case is 2 route hops.

Configuring Multiple-Point Routes

For multi-location enterprises, CN2600 servers can be placed in different branch offices and used as bo th multi-point routers and as remote access servers. When hosts (e.g., the Web/FTP and E-mail/News s ervers shown in the figure) send requests to hosts on another network, such as 202.6.6.xxx or 201.2.2.xxx, the corresponding CN2600 delivers the request to the another CN2600 on the remote end, 202.6.6.254 or

201.2.2.254, as the next-hop router.. For this example, assume that Modem 1 is connected to serial port 1, Modem 2 is connected to serial port 2, and

PPP source and destination IP addresses of modems 1, 2, 3, and 4 are as follow s:

Source IP Destination IP Source IP Destina t ion IP Modem 1 203.67.6.250 202.6.6.250 Modem 3 202.6.6.250 203.67.6.250 Modem 2 203.67.6.249 201.2.2.249 Modem 4 201.2.2.249 203.67.6.249

In this case, you will need to add two entries to the routing table, as shown in the following figure.

Port Setting Basics

Each serial port on the CN2600 can be configured independently. To configure the operation mode and settings for a port, expand Serial Port Settings in the navigation p a nel, then expand the port that you would like to configure. Individual port settings are grouped into four c ategories in the navi gation panel: Operati on Modes, Communication Parameters, Data Buffering/Log, and Modem Settings.

Select Operation Modes in the navigation panel to select and configure the mode for each serial port. For CN2600 models with 2 or more serial ports, you may use the checkboxes at the bottom of the window to apply the settings to one or more ports.

Application: Select an application for the serial port from among the choices. Your application will determine the modes that are available.

Mode: Once you have chosen an application, select the mode. The available configuration settings will vary depending on the mode that you have s elected.

CN2600 Series Configuring Serial Port Operation Modes

6-3

ATTENTION

When Max connection is greater than 1, the CN2600 will use a multi connection application (i.e., 2 to 8 hosts are allowed access to the port at the same time). When using a multi connection application, the CN2600 will use the serial communication par a meters as defined here in the web console, and all hosts connected to the port must use identical serial settings. If one of the hosts opens the COM port with different serial settings, data will not be transmitted properly.

Device Control Applications

Real COM Mode

multiple hosts’ Real COM drivers open the port at the same time, the COM driver only provides a pure data tunnel—no control ability. The serial port parameters will use firmware settings instead of depending on your application program (AP).

Application software that is based on the COM driver w ill receive a driver response of “success” when the software uses any of the Win32 API functions. The firmware will only send data back to the driver on the host.

Data will be sent first-in-first-out when data comes into the CN2600 from the Ethe rnet interface.

Ignore jammed IP (default=No): This option determines how the port will proceed if multiple hosts are connected and one or more of the hosts stops responding as the port is transmitting data. If you select No, the port will wait until the data has been transmitted successfully to all hosts before transmitting the next group of data. If you select Yes, the port will ignore the host that stopped responding and continue data transmission to the other hosts.

Allow driver control (default=No): This option determines how the port will proceed if driver control commands are received from multiple hosts that are connected to the port. If No is selected, driver control commands will be ignored. If Yes is selected, control commands will be accepted, with the most re cent command received taking precedence.

Connection goes down (default=always high): You can configure what happens to the RTS and DTR signals when the Ethernet connection goes down. For some applications, serial devices need to know the Ethernet link status through RTS or DTR signals sent through the ser ial port. Use goes low if you want the RTS and DTR signal to change their state to low wh en the Ethernet connection goes down. Use always high if you do not want the Ethernet connection status to affect the RT S or DTR signals.

ATTENTION

In order to enable a delimiter, packet length must be set to 0. Delimiter 2 should only be enabled in conjunction with Delimiter 1 and never on its own; otherwise there may be data errors. Even when a delimiter is enabled, the CN2600 will still pack and send the data when the amount of data exc eeds 1 KB.

Packet length (default=0): The Packet length setting refers to the maximum amount of data that is allowed to accumulate in the serial port buffer before sending. At the default of 0 for packet length, no maximu m amount is specified and data in the buffer will be sent as specified by the delimiter settings or when the buffer is full. When a packet length betw een 1 and 1024 bytes is specified, data in t h e b uffer will be sent as soon it reaches the specified length.

Delimiter 1 and Delimiter 2 (default=None): When Delimiter 1 is enabled, the serial port will clear the buffer and send the data to the Ethernet port when a specific character, entered in hex format, is received. A second delimiter character may be enabled and specified in the Delimiter 2 field, so that both characters act as the delimiter to control when data shou ld b e sent.

Delimiter process (default=Do Nothing): The Delimiter process field determines how the data is handled when a delimiter is received. Delimiter 1 must be enabled for this field to have effect. If Delimiters 1 and 2 are both enabled, both characters must be received for the delimiter process to take place.

• Do Nothing: Data in the buffer will be tr a nsmitted when the delimiter is r eceived.

• Delimiter + 1: Data in th e buffer will be tran s mitted after 1 additional byte is received following the

delimiter.

• Delimiter + 2: Data in the buffer will be transmitted after 2 additional bytes are received following the

delimiter.

• Strip Delimiter: Data in the buffer is first stripped of the delimiter befor e being transmitted. Force transmit (default=0 ms): This parameter defines how large a gap in serial communication the CN2600

will allow before packing the serial data in its internal buffer for network transmission. As data is received through the serial port, it is stored by the CN2600 in t he internal buffer. The CN2600

transmits data stored in the buffer via TCP/IP, but only when the internal buffer is full or as specified by the force transmit time. When set to 0, the force transmit time is disabled, and transmission is determined solely by the data in the internal buffer. At 1 to 65535, the TCP/IP protocol software will pack the serial data received after there is a gap in serial communication that exceeds the specified force transmit time.

The optimal force transmit time depends on your application, but it must be at least larger than one character interval within the specified baudrate. For example, assume that the serial port is set to 1200 bps, 8 data bits, 1 stop bit, and no parity. In this case, the total number of bits needed to send a character is 10 bits, and the time required to transfer one character is

(10 (bits) / 1200 (bits/s)) × 1000 (ms/s) = 8.3 ms. Therefore, you should set the force transmit time to be larger than 8.3 ms, so in this case, it must be greater

than or equal to 10 ms. If it is necessary to send a series of characters in the same packet, the serial device will need to send that series

of characters within the specified force transmit time, and the total length of data must be less than or equal to the CN2600’s internal buffer size (1 KB per port).

Even when a delimiter is enabled, the CN2600 will still pack and send the data when the amount of data exc eeds 1 KB.

RFC2217 Mode

TCP alive check time (de fault=7 min): This field specifies how long the CN2600 will wait for a response to

“keep alive” packets before closing the TCP connection. The CN2600 checks connection status by sending periodic “keep alive” packets. If the remote host does not respond to the packet within the time specified in this field, the CN2600 will force the existing TCP connection to close. For socket and device control modes, the CN2600 will listen for another TCP connection from another host after closing the connection. If TCP alive check time is set to 0, the TCP connect ion will remain open even if there is no response to the “keep alive” packets.

TCP port (default=4001): This is the TCP port number assignment for the serial port on the CN2600. It is the port number that the serial port uses to listen to connections, and that other devices must use to contact the serial port. To avoid conflicts with well known TCP ports, the default is set to 4001.

Packet length (default=0): The Packet length setting refers to the maximum amount of data that is allowed to accumulate in the serial port buffer before sending. At the default of 0 for packet length, no maximum amount is specified and data in the buffer will be sent as specified by the delimiter settings or when the buffer is full. When a packet length betw een 1 and 1024 bytes is specified, data in t h e b uffer will be sent as soon it reaches the specified length.

Delimiter 1 and Delimiter 2 (default=None): When Delimiter 1 is enabled, the serial port will clear the buffer and send the data to the Ethernet port when a specific character, entered in hex format, is received. A second delimiter character may be enabled and specified in the Delimiter 2 fi eld, so that both characters act as the delimiter to indicate when data should be sent.

Delimiter process (def a ult=Do Nothing): The Delimiter pr ocess field determines how the data is handled when a delimiter is received. Delimiter 1 must be enabled for this field to have effect. If Delimiters 1 and 2 are both enabled, both characters must be received for the delimiter process to take place.

Max connection (default=1): This field is used if you need to receive data from different hosts simultaneously. When set to 1, only a single host may open the TCP c onnection to the serial port. Wh en set to 2 or greater, u p to the specified number of hosts may open this port at the same time. When multiple hosts establish a T C P connection to the serial port at the same time, the CN2600 will duplicate the serial data and transmit it to all the hosts. Ethernet data is sent on a first-in first-out basis to the serial port when data comes into the CN2600 from the Ethernet interface.

Ignore jammed IP (default=No): This option determines how the port will proceed if multiple hosts are connected and one or more of the hosts stops responding as the port is transmitting data. If you select No, the port will wait until the data has been transmitted successfully to all hosts before transmitting the next group of data. If you select Yes, the port will ignore the host that stopped responding and continue data transmission to the other hosts.

Allow driver control (default=No): This option determines how the port will proceed if driver control commands are received from multiple hosts that are connected to the port. If No is selected, driver control commands will be ignored. If Yes is selected, control comma nd s will be accepted, with the most re cent command received taking precedence.

TCP port (default=4001): This is the TCP port number assignment for the serial port on the CN2600. It is the port number that the serial port uses to listen to connections, and that other devices must use to contact the serial port. To avoid conflicts with well known TCP ports, the default is set to 4001.

Command port (default=966): The Command port is the TCP port for listening to SSDK 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.

Packet length (default=0): The Packet length setting refers to the maximum amount of data that is allowed to accumulate in the serial port buffer before sending. At the default of 0 for packet length, no maximum amount is specified and data in the buffer will be sent as specified by the delimiter settings or when the buffer is full.

• Delimiter + 1: Data in th e buffer will be tran s mitted after 1 addit ional byte is received following the

delimiter.

• Delimiter + 2: Data in the buffer will be transmitted after 2 additional bytes are received following the

delimiter.

• Strip Delimiter: Data in the buffer is first stripped of the delimiter before being transmitted. Force transmit (default=0 ms): This parameter defines how large a gap in serial communication the CN2600

will allow before packing the serial data in its internal buffer for network transmission. As data is received through the serial port, it is stored by the CN2600 in the internal buffer. The CN2600

transmits data stored in the buffer via TCP/IP, but only when the internal buffer is full or as specified by the force transmit time. When set to 0, the force transmit time is disabled, and transmission is determined solely by the data in the internal buffer. At 1 to 65535, the TCP/IP protocol software will pack the serial data received after there is a gap in serial communication that exceeds the specified force transmit time.

The optimal force transmit time depends on your application, but it must be at least larger than one character interval within the specified baudrate. For example, assume that the serial port is set to 1200 bps, 8 data bits, 1 stop bit, and no parity. In this case, the total number of bits needed to send a character is 10 bits, and the time required to transfer one charac ter is

(10 (bits) / 1200 (bits/s)) × 1000 (ms/s) = 8.3 ms. Therefore, you should set the force transmit time to be larger than 8.3 ms, so in this case, it must be greater

than or equal to 10 ms. If it is necessary to send a series of characters in the same packet, the serial device will need to send that series

of characters within the specified force transmit time, and the total length of data must be less than or equal to the CN2600’s internal buffer size (1 KB per port).

TCP Client Mode

TCP alive check time (de fault=7 min): This field specifies how long the CN2600 will wait for a response to

“keep alive” packets before closing the TCP connection. The CN2600 checks connection status by sending periodic “keep alive” packets. If the remote host does not respond to the packet within the time specified in this field, the CN2600 will force the existing TCP connection to close. For socket and device control modes, the

Inactivity time is O NL Y ac

ATTENTION

Up to 4 connections can be establis h ed between the CN2600 and hosts. The con n ection speed or throughput may be low if any one of the four connections is slow, since the one slow connection will slow down the other 3 connections.

ATTENTION

The Destination IP address parame ter can be the IP address, domain name, or the name defined in the host table. For some applications, the user may need to send the data actively to the r emote des name.

CN2600 will listen for another TCP connection from another host after closing the connection. If TCP alive check time is set to 0, the TCP connect io n will remain open even if there is no re sp onse to the “keep alive” packets.

Inactivity time (default=0 ms): This field specifies how long the CN2600 will wait for incoming and outgoing data through the serial port before closing the TCP connection. The TCP connection is closed if there is no incoming or outgoing data through the serial port for the specified Inactivity time. If this field is set to 0, the TCP connection is kept active until a connection close request is rece ived.

Ignore jammed IP (default=No): This option determines how the port will proceed if multiple hosts are connected and one or more of the hosts stops responding as the port is transmitting data. If you select No, the port will wait until the data has been transmitted successfully to all hosts before transmitting the next group of data. If you select Yes, the port will ignore the host that stopped responding and continue data transmission to the other hosts.

Destination address 1 through 4 (default=None): Specifying an IP address allows the CN2600 to connect actively to the remote host. At least one destination must be provided.

TCP port (default=4001): This is the TCP port number assignment for the serial port on the CN2600. It is the port number that the serial port uses to listen to connections, and that other devices must use to contact the serial port. To avoid conflicts with well known TCP ports, the default is set to 4001.

Destination address 1 through 4 (default=None): In UDP mode, you may specify up to 4 ranges of IP

addresses for the serial port to connect to. At least one destination range must be provided.

Local listen port (default=4001): This is the UDP port that the CN2600 listens to and that other devices must use to contact the CN2600 . To avoid conflicts with well known UDP ports, the default is set to 4001.

Redundant COM

Max connection (default=1): This field is used if you need to receive data from different hosts simultaneously.

When set to 1, only one specific host can access this port of the CN2600, and the Redundant COM driver on that host will have full control over the port. When set to 2 or greater, up to the specified number of hosts’ Redundant COM drivers may open this port at the same time. When multiple hosts’ Redundant COM drivers open the port at the same time, the COM driver only provides a pure data tunnel—no control ability. The serial port parameters will use firmware settings instead of depending on your application program (AP).

Application software that is based o n the COM driver will receive a driver response of “success” when the software uses any of the Win32 API functions. The firmware will only send data back to the driver on the host.

Data will be sent first-in-first-out when data comes i n to the CN2600 from the Ethernet interface.

CN2600 Series Configuring Serial Port Operation Modes

ATTENTION

When Max connection is greater than 1, the CN2600 will use a multi connection application (i.e., 2 to 4 hosts are allowed access to the port at the same time). When using a multi connection application, the CN2600 will use the serial communication par a meters as defined here in the web con sole, and all hosts connected to the port must use identical serial settings. If one of the hosts opens the COM port with different serial settings, data will not be transmitted properly.

If you select Yes, the port will ignore the host that stopped responding and continue data transmission to the other hosts.

Allow driver control (default=No): This option determines how the port will proceed if driver control commands are received from multiple hosts that are connected to the port. If No is selected, driver control commands will be ignored. If Yes is selected, control commands will be accepted, with the most recent command received taking precedence.

Connection goes down (default=always high): You can configure what happens to the RTS and DTR signals when the Ethernet connection goes down. For some applications, serial devices need to know the Ethernet link status through RTS or DTR signals sent through the ser ial port. Use goes low if you want the RTS and DTR signal to change their state to low wh en the Ethernet connection goes down. Use always high if you do not want the Ethernet connection status to affect the RT S or DTR signals.

Accessible IP List

The CN2600 uses an IP address-based f iltering method to control access to its serial ports. The Accessible IP list allows you restrict network access to the CN2600 . Access is controlled by IP address.

When the accessible IP list is enabled, a host’s IP address must be listed in order to have access to the CN2600. You may add a specific address or range of addresses by using a combination of IP address and netmask, as follows:

To allow access to a specific IP address Enter the IP address in the correspo n ding field; enter 255.255.255.255 for the netmask.

To allow access to hosts on a specific subnet For both the IP address and netmask, use 0 for the last digit (e.g., 192.168.1.0 and 255.255.255.0).

To allow unrestricted access

Deselect the Enable the accessible IP list option. Refer to the following table for more configuration examples.

On the Event Settings page, you may configure how administrators are notified of certain system, network, and configuration events. Depending on the event, different options for automatic notification are available, as shown above. Mail refers to sending an e-mail to a specified address. Trap refers to sending an SNMP Trap.

Cold start: This refers to starting the system from a power off state, or after upgrading your firmware Warm start: This refers to restarting the CN2600 without turning the pow er off. Power down: Power1 and Power2 refer to the built-in power jacks. If either power fails, the CN2600 will

attempt to send an e-mail warning. Network Event: Ethernet1 and Ethernet2 refer to the built-in Ethernet ports. These settings configure the

CN2600 to change the status of the relay output and alarm LED if the specified connection goes down. Console(web/text) login auth fail: This field refers to a failed attempt to log in to a password- protected

CN2600 console. IP changed: With this option selected, the CN2600 will attempt to se n d an e-mail warning before it reboots

after an IP address change. However, the CN2600 will reboot with the new IP address regardless of whether or not the e-mail transmission is suc ce ss fu l.

Password changed: With th i s option selected, the CN2600 will attempt to send an e-mail warning before it reboots with a new console password. If the CN2600 is unable to send an e-mail message to the mail server within 15 seconds, it will still r eb oot without sending the e-mail.

Serial Event Settings

On the Serial Event Settings page, you may configure how administrators are notified of each serial port’s DCD and DSR changes. Mail refers to sending an e-mail to a specific address. Trap refers to sending an SNMP Trap.

DCD changed

A change in the DCD (Data Carrier Detect) signal indicates that the modem connection status has changed. For example, if the DCD signal changes to low, it indicates that the connection line is down. When the DCD signal changes to low, the CN2600 will automatically send a warning to the administrator as configured on the Serial Event Settings page.

DSR changed

A change in the DSR (Data Set Ready) signal indicates that the data communication equipment is powered off. For example, if the DSR signal changes to low, it indicates that the data communication equipment is powered down. When the DSR signal changes to low, the CN2600 will automatically send a warning to the administrator as configured on the Serial Event Settings page.
