2.3. Accessing Console Port There are two ways to access console port of the HelloDevice Pro Series depending on whether the user is located at a local site or a remote site. - Serial console: Local users can connect directly to the serial console port of the HelloDevice Pro Series using serial console cable (null-modem cable). - Remote console: Remote users can make a telnet connection to the remote console port (port 23) of the HelloDevice Pro Series via TCP/IP network.
2) Connect the other end of the cable to the serial port of user’s computer. 3) Run a terminal emulator program such as HyperTerminal. Set up the serial configuration parameters of the terminal emulation program as follows: 9600 Baud rate, Data bits 8, Parity None, Stop bits 1, Hardware flow control (RTS/CTS) 4) Press [ENTER] key. 5) Type the user name and password to log into the HelloDevice Pro Series. A factory default setting of the user name and password are both admin.
2.3.2 Using Remote console The IP address of the HelloDevice Pro Series must be known before users can access the remote console port (See IP Address Configuration in chapter 3 for details). Remote console access function is optional, and can be disabled in the remote access option on the menu (See Remote Host Access Control in section 5.1 for details). This is useful when system administrator does not want others to modify the existing configuration.

Users’logging into the HelloDevice Pro Series (PS400) 3) If the user logged into the HelloDevice Pro Series successfully, the same main menu screen as the one of serial console will be displayed.
3: IP Address Configuration A valid IP address of the HelloDevice Pro Series needs to be assigned before it starts to work in the user's network environment. A network system administrator may provide the user with this IP address setting information for the network. The IP address must be unique within the network. Otherwise, the HelloDevice Pro Series will not have a valid connection to the network. Users can choose the desired IP mode out of the three IP operating modes, i.e.
3.1.2 IP address In the Static IP mode, the IP address is an identification number assigned to a computer as a permanent address on the network. Computers use IP addresses to identify and talk to each other on the network. Choose the proper IP address which is unique and valid on the network environment. ---> 2 Enter IP address: 192.168.1.100[ENTER] Figure 3-2.

For correct information on the gateway IP address, please refer to the network administrator. ---> 4 Enter default gateway: 192.168.1.1[ENTER] Figure 3-4. Setting the default gateway in Static IP mode 3.1.4 Primary and Secondary DNS When users want to visit certain website, the computer asks a Domain Name System (DNS) server for the correct IP address of the web site, and the computer uses the answer to connect to the web server.
servers will be automatically configured when the IP address is assigned in DHCP mode. DHCP uses the concept of a "lease" or amount of time for which a given IP address will be valid for a computer. All the parameters required to assign an IP address are configured on DHCP server side, and each DHCP client computer receives this information when the IP address is provided at its boot-up.
3.3 PPPoE 3.3.1 Overview PPPoE (PPP over Ethernet) is a specification for connecting multiple computer users on an Ethernet local area network to a remote site through common customer premises equipment, which is the telephone company's term for a modem and similar devices. PPPoE can be used to have an office or building-full of users share ADSL, cable modem, or wireless connection to the Internet. Usually, it is used in broadband Internet access such as ADSL.
3.3.2 PPPoE setting To make the HelloDevice Pro Series work in PPPoE mode, users need to configure the PPPoE username and password for their ADSL account. --------------------------------------------------------------------------IP configuration --------------------------------------------------------------------------Select menu 1. IP mode : PPPoE 2. Change PPPoE username : whoever 3.
4: Serial Port Configuration Serial port configuration screen can be reached through menu 2 in the main menu screen. Serial port configuration menu contains four groups of the parameters such as Host mode configuration, UART configuration, Cryptography configuration and additional options for serial data communication. Users need to set up all those parameters for each serial port considering the serial device that will be hooked up to the serial port.

4.1 Host mode configuration 4.1.1 Overview Host mode represents the operating session mode of the HelloDevice Pro Series. Several host modes are available for the data communication between serial devices and remote hosts. Since TCP is connection-oriented protocol, server, client, server/client modes are provided. Other than those TCP based modes, UDP mode is provided for connectionless communication.
A factory default host mode is TCP Server, and users can select the mode by using the menu, Serial Port Configuration–host mode Configuration–Host mode. --------------------------------------------------------------------------serial configuration -->port#1 --> TCP/IP --------------------------------------------------------------------------Select menu 1. Host mode : TCP Server 2.
- Data When it is in [Established] state, data from a host will be transferred to the other one. For easier understanding of the TCP session operation, we called the state as [Data] state when actual data transfer is performed. Actually, the [Data] mode is a part of [Established] state as is described in the RFC 793 [Transmission Control Protocol]. This is a normal state for the data transfer phase of the connection. 4.1.
IP address filtering The HelloDevice Pro Series will not accept the incoming connection request from the remote hosts which are not in the host list (See Remote Host Access Control in section 5.1 for details). Figure 4-4 shows the State Transition Diagram of the session operations in TCP server mode.

or when no data transfer activity is found through the serial port for certain amount of time, which is “Inactivity timeout” (See Options in section 4.4 for details on Inactivity timeout). All the data remained in the serial port buffer will be cleared when it is disconnected. Connection request from remote host All the incoming TCP connection requests will be rejected in TCP client mode.
3) Parameters Remote IP address (or domain name) and Remote Port This is the information on the remote host to which the HelloDevice Pro Series will try to connect in TCP client mode. The IP address (or domain name) should be specified together with the TCP port number. To specify the information on the remote host, select menu 2 on the TCP Client mode configuration screen. The format of remote host information is as follows. [IP address (or domain name)]:[TCP Port number] e.g.) 211.116.20.

4.1.7 Modem emulation mode operations In modem emulation mode, the serial port process acts as if it is a modem attached to the serial device. It accepts AT modem commands and answers to them, as modems would do. It also handles the modem signals correctly. Modem emulation mode is useful in the following cases. - There already exists a modem attached to the users’serial device.
