*Note – PoEx is a simple adaptation of the IEEE 802.3af Power over Ethernet (PoE) standard to bring the benefits to the 9400 Range of Hazardous Area devices. This allows two spare pairs in the existing Cat5e cable to distribute the power supply from a 9466 Ethernet Switch (Power Sourcing Equipment – PSE) to each of the devices connected to its five ports (PD – Powered Device). This adaptation is necessary due to restrictions for Hazardous Area use. It is not implied that the device conforms to the 802.3af (PoE) standard.

2 DESCRIPTION
The 9469-ETplus 108Mbps Wireless Bridge / Access Point is a dual functionality module. When used in the Access Point (AP) mode, it allows wireless devices to connect through it onto the wired Ethernet network, either in Ad-hoc or Infrastructure modes. When used as a Bridge, it makes it possible to turn any 10/100 Ethernet device into a wireless device, or to connect two network segments together to make a single network (without the interconnecting wire or fibre optic). Additionally the module may also be used in its Wireless Repeater (WDS) mode to extend the range covered by a wireless network.
The Tri-Band operation offers flexibility in situations where the 2.4GHz band may be overcrowded or where operation in the 5GHz and 5.4GHz bands is desired. The unit supports 802.11d (multi­country roaming) to allow its use globally while complying with regulatory limits.
3 INSTALLATION
WARNING: This equipment must be installed, operated and maintained only be trained competent
personnel and in accordance with all appropriate international, national and local standard codes of practice and site regulation for intrinsically safe apparatus and in accordance with the instructions contained here. See also Sections 14, 15 & 16 for approvals and important conditions of safe use.
3.1 Protection
The module requires mounting within an enclosure providing a degree of protection of at least IP6x, in accordance with EN60529 and in a manner that does not impair the existing creepage and clearance distances. The enclosure must also comply with the requirements of Clauses 7 and 8 of EN 60079-0:2006 and be sealed to prevent the ingress of dust.
3.2 Mechanical mounting
3.2.1 DIN rail mounting
The module will ‘snap-fit’ onto standard DIN rail (TS35) to EN 50022. Height off rail - including connectors but excluding cables = 119mm.
Tilt the module to engage the top DIN rail clips then rotate down and press to the DIN rail until the lower spring clip is properly engaged.
3.2.2 Flat panel mounting
The module has two fixing holes to enable it to be mounted with two M3.5 screws. Use the template below to establish hole positions. Depth - including connectors but excluding cables = 124mm.

3.3 Electrical connections
DC power can be supplied to the equipment through the front panel screw terminals or alternatively using the Power over Ethernet (PoEx) option where DC power is supplied from a 9466-ET module down the Ethernet Cat5e (or Cat6) cable into the RJ45 connector on the front panel.
WARNING: Whichever wiring method of powering the modules is used, the supply to them must be derived from a suitably certified, intrinsically safe supply.

♦ When connecting the Cat5e cable to another device a straight connected RJ45 cable is used,
a crossover cable is not required as the RJ45 connector performs the crossover.
♦ It is recommended that Cat5e cables for Hazardous Area Zone 1 use are ‘Blue’ in colour and
are of good quality (see Accessories section), the Safe Area cables being a colour other than blue to aid identification.
3.3.3 WiFi - SMA – Antenna Connections Main Port Antenna 1
Aux Port Antenna 2
Allows the connection of up to two antennae for diversity
The Antenna may be 2.4GHz, 4.9/6GHz or Tri-Band types as required
The antenna should be connected to the SMA socket labelled Main Port. It can be connected directly or through low-loss 50 ohm co-axial cable, which might be required if the module is housed in a metal enclosure, or the position of the antenna needs to be optimised.
The Aux Port may be used for a second antennae if diversity is required.

4 GETTING STARTED
4.1. Select Working mode
The 9469-ETplus creates a link between your Ethernet and a WiFi Network
It can be configured to operate in one of two different modes: Access Point or Bridge, but the default mode is Access Point
4.1.1. Access Point
In Access Point mode, the 9469-ETplus becomes a communications hub to enable various items of WiFi equipment (set in “infrastructure” mode) to connect into a wired Ethernet network.
4.1.2. B ri dge
In this mode, the 9469-ETplus gives wired Ethernet output equipment access to a WiFi network. (Use “infrastructure” mode to connect to an existing access point, otherwise use “adhoc” mode.)
4.2. Collect Network Parameters
In order to configure the 9469-ETplus, you will need to have the following pieces of information.
♦ WiFi Network identifier “SSID”
The SSID is a character string used to identify your WiFi network. To share the same WiFi network, your device and the other WiFi equipment must use the same SSID. The SSID is up to 32 characters in length. Uppercase and lowercase letters are considered different.
♦ Radio Channel
You must choose a radio channel in addition to the SSID to define the transmission frequency the device will use to communicate with other equipment. It is recommended to use less than 3 channels in the same covered area in order to avoid disturbances. It is also recommended to leave at least two unused channels between each radio channel. In Ad-hoc mode, all the equipment must have the same radio channel. Legislation is different in each country; check what channels you can use in the country where the device is installed.
♦ Device IP Address
If you don’t use DHCP, you must define an IP address for the device. To assign an IP address, contact the network administrator.
♦ LAN Subnet Mask
You must configure a subnet mask for the device. Refer to the subnet mast of your local network. Consult the network administrator if in doubt.
♦ Gateway Address (if required)
♦ WEP or WPA Security keys
5 LOCATING ON THE NETWORK
In order to locate the device on the network, use the locator program supplied. This is a simple standalone application that does not require installation, just copy the file to your hard drive
Connect the device to the network and run the locator.exe program.
The locator program offers the following functions
♦ Scan
When you click this button locator looks for the device on the network.
♦ Configure
When you click this, you can configure the IP Address or enable DHCP.
♦ Upgrade
This button is not implemented within the 9469-ETplus.
♦ Web
Clicking this launches the Administrator web page of the device is brought up.
Page 9

INM9469-3
Note. If the device is behind a gateway the locator program will not find it. Use a computer on the same local network as the device for initial setup.
If a firewall is installed on the computer ensure that UDP port 17784 is not blocked
6 WEB CONFIGURATION
To configure the device, run the administration web page. There are two ways to do this
♦ Run your web browser and, if known, enter the IP address in the address field.
(Note: the default IP address is 192.168.1.253)
♦ Locate the device using the locator program mentioned in Section 5, then click on the Web button.
Once on the Web pages a screen appears as below. Initially there is no password.
7 SWITCHING BETWEEN ACCESS POINT AND BRIDGE
To change the operating mode, enter the menu BASIC->WIRELESS and choose the firmware you want to use. Then click on Save Settings and Reboot the Device. The device will then restart and use the selected firmware.
8 DEVICE CONFIGURATION
The administration pages consist of the following five categories
♦ Basic
Configure IP addresses, 802.11 mode, radio channel, SSID, security.
♦ Advanced
Configure MAC address filtering
♦ Tools
Set User password, admin password, view firmware version, upgrade firmware
♦ Status
Device info, IP addresses, Radio Channel, Connected devices.
♦ Help
Comprehensive help on all the parameters
9 UPGRADE
In order to upgrade the device follow the steps below
♦ Open the administration web page
♦ Click on tools -> Firmware
In the firmware upgrade section browse to select the new firmware file
♦ Click on Upload
♦ If the upgrade is successful the device will restart
