[Table 1.4.1] Specification 2. Installation 2.1 Fundamentals of wireless LAN CMAX Module supports IEEE802.11b/g. The IEEE802.11b and IEEE802.11g support 11Mbps and 54Mbps transmission rate respectively. There are two types of wireless LAN networks infrastructure and ad-hoc. 8

[Figure 2.1.1] Reference Network Architecture 2.1.1 Infrastructure Mode The wireless LAN stations communicate through an Access Point (AP). So, at least one AP is needed to make the infrastructure network. The wireless LAN station can talk to wired network hosts because AP relays between wireless LAN stations as well as between wireless LAN station and wired LAN (Ethernet) host.

[Figure 2.1.1.1] Infrastructure 2.1.2 Ad-hoc Mode Wireless stations communicate each other without the AP. So user can make a system more simply. It is proper if theres no wired LAN requirement and it is a small network. Some people call it peer-to-peer mode. 9

[Figure 2.1.2.1] Ad-Hoc 2.1.3 Basic Requisites SSID It is an identifier to identify the particular wireless LAN. So the same SSID should be configured to all stations to communicate in the same wireless network. In case of infrastructure mode, user has to set his stations SSID as same as APs. Channel IEEE802.11b/g wireless LAN stations communicate through the ISM (Industrial, Scientific, and Medical) band whose frequency is about 2.4GHz. IEEE802.11 specification divides this band into 14 channels every 5MHz. If user installs more than one wireless LAN networks in the same area, the channels should be apart more than 4 channels to avoid interferences. 2.1.4 Authentication and Security Authentication A wireless LAN station should get authentication from the AP in the infrastructure mode. There are the Open system and the Shared key for the authentication methods. WEP (Wired Equivalent Privacy) The WEP is a secure protocol for wireless LAN. There are two kinds of WEP method - 64 bits and 128 bits key. WPA (Wi-Fi Protected Access) WPA is a security standard for users of device equipped with Wi-Fi wireless connection. It is an improvement on and is expected to replace the original Wi-Fi security standard, Wired Equivalent Privacy (WEP). There are two modes about the user authentication in WPA security. The one is Enterprise which has authentication server and the other one is 10 PSK (Pre-Shared Key) which doesnt have any server. CMAX Module supports both Enterprise mode and Personal mode (WPA-PSK). WPA 2 To final security of Wireless LAN, IEEE 802.11i, a standard about Wireless LAN, has suggested the Counter Mode with Cipher Block Changing Message Authentication Code Protocol (CCMP) for replacing the TKIP. CCMP uses Advanced Encryption Standard (AES), it is the WPA 2 that adopts the using the method. WPA 2 has also both Enterprise and PSK mode. CMAX Module supports also both them. 2.2 Installation Before testing, users should connect the CMAX Module. There are two methods for connecting. The first method is to connect a target device with the serial port and the other method is to connect by wireless LAN card on your PC.

[Figure 2.2.1] Connect between CMAX Module and a PC 2.2.1 Making Wireless LAN Network Even though you connect an AP on your network, wireless LAN network could not be made automatically. You should configure values of items which related with wireless network. Please follow the below steps. Connect the CMAX Module through serial port Start the WLAN Module Manager on your PC. Push the Connect button after Selecting a COM port, User ID and User Password as the same values with the your COM port. 11

[Figure 2.2.1.1] Connect through serial port Connect the CMAX Module through WLAN Start the WLAN Module Manager on your PC. Click the Connect button after inserting IP Address, User ID and User Password as the same values with the CMAX Module.

[Figure 2.2.1.2] Connect through WLAN Configuring Wireless LAN Parameters Move to the [Network] menu and setting SSID as the same values with the APs. Then, move to the [Authenticaton] menu and setting security options. Finaly, Click the Update button. Please ask the manufacturer of the AP, when you want to know about setting the APs value. 12

[Figure 2.2.1.3] Configuring Wireless LAN Parameters If you want to make an Ad-hoc network, choose the [Ad-hoc] as the value of [WLAN Topology] and set a value of [SSID]. Then, try to connect your PC to the network. 2.2.2 Setting Network Aera This step is for setting both CMAX Module and your PC to be located the same network. If only they are, the TCP connection between them can be established. Setting of the PC Add or change the IP address of the network adapter on your PC like following. Get into the menu of [Windows Control Panel] >> [Network Connections] >> [Properties of the Network Adapter - with right click of your mouse]. Then, you can show the properties of [Internet Protocol (TCP/IP). In there, press the [Advanced] button for adding an IP Address like the below figure.

[Figure 2.2.2.1] adding / changing the IP address of users PC Setting of CMAX Module CMAX Module uses WLAN Module Manager as its a configuration program. WLAN Module Manager is for MS Windows, and this is comfortable to use because it doesnt 13 need installation. First, search your WLAN Module via network. All the values of parameters are set the default values in the factory. To apply it to your system, proper values should be set via WLAN Module Manager. Major parameters default values are listed on below table. To implement this simple test, keep these values without any changes.

Note :

SNMP stands for 'Simple Network Management Protocol' and it is used for network management. SNMP is only a protocol to transfer messages so it need the Application program to get Network management information using SNMP. SNMP has SNMP manager and agent, as in common network application is composed server and client model. SNMP agent is a part of SNMP module and it is installed in managed system to collect the network or system information. SNMP manager is also part of the SNMP module and it request the network information to SNMP agent. 3.5.1 SNMP Connection

: It should be connect a SNMP Agent through SNMP Manager. It is introduced a SNMP operation at this manual as used SNMP-JManger-v1.0. SNMP-JManager-v1.0 running

- Input the address(192.168.192.168 , CMAX modules IP Address) to Agent IP Address. Default : IP Address : 192.168.192.168

- Input the Read Community, Write Community and then click Apply Changes button. Default : Read Community : public Write Community : private 40

[Figure 3.5.1.1] SNMP Connection configuration screen 3.5.2 SNMP Manager operation test: it is description of basic SNMP operation. If you selected terminal node to Get Tree, get this value(client note value).

[Figure 3.5.2.1] SNMP get message operation screen 41 Get Next : You can bring the value at trees as selected a terminal node.

[Figure 3.5.2.2] SNMP getnext message opration screen You can configure the terminal node value to set tree. (You can set only the contents had set on "Write")

[Figure 3.5.2.3] SNMP set message operation screen 42 Walk: It can get the all item that terminal node of tree or terminal node of node.

[Figure 3.5.2.4] SNMP walk message operation screen Traps: If a specific event occurs, relevant(in the event) message is transmitted to trap address.

- ColdStart: when a terminal rebooting works, coldstart message is transmitted to trap address.

[Figure 3.5.2.5] SNMP coldStart message received screen

- AuthenticationFailure: If Read, Write Community is not correct, AuthenticationFailure message is transmitted to trap address. 43

[Table 4.1.1] Hardware Pin Arry 5. Demo and Test This chapter explains several examples that it can be used for functional testing of CMAX module. Test environment is as follows. 5.1 Test environment 5.1.1 Hardware RS232 serial port with a PC CMAX module & CMAX test board PC's COM port and CMAX for the module's serial port to connect the serial cable is required. 5.1.2 Software 45 Configuration Tool of CMAX module Hyper Terminal( or other Terminal program) 5.2 Start Test 5.2.1 STEP1. It should be connect to CMAX Test board and PCs Serial port. It should be turn on the CMAX test board. It should be connected the PC to CMAX module through serial interface. It should be run a Terminal program of PC by connected Serial(ex, HyperTerminal) 5.2.2 STEP2. (Wireless Configuration to between CMAX module and PC). It should be connected the PC to CMAX module through wireless LAN. It should be configured the PCs Network to next value. IP( 192.168.192.XXX), subnet(255.255.255.0), gateway(192.168.192.1) It should be confirmed wireless connection of CMAX module and PC by Ping response. 5.2.3 STEP3. (Data Transfer) It should be run a Terminal program of PC by connected WLAN(ex, HyperTerminal) It should be input a charater to HyperTerminal. It should be confirmed a Receive Data on serial Terminal.
