905U-E Wireless Ethernet Bridge 2.3 The 905U-E module is powered by a 10 - 30VDC supply. The power supply should be rated at 1 Amp and be CSA Certified Class 2. User Manual Power Supply 905U-E + The negative side of the supply is connected to "COM" 10 – 30 + and may be connected to “ground”. The supply negative VDC is connected to the “GND” terminal internally. The positive side of the supply must not be connected to earth. The supply may be a floating supply or negatively grounded.
Chapter Two Installation 905U-D DB9 MALE DTE HOST DB9 FEMALE 905U-D DB9 MALE DCE HOST DB9 MALE Hardware handshaking using the CTS/RTS lines is provided. The CTS/RTS lines may be used to reflect the status of the local unit’s input buffer, or may be configured to reflect the status of CTS/RTS lines at the remote site. The 905U-D does not support XON/XOFF. Example cable drawings for connection to a DTE host (a PC) or another DCE host (or modem) are detailed above.
905U-E Wireless Ethernet Bridge User Manual As the RS485 communication medium is shared, only one of the units on the RS485 cable may send data at any one time. Thus communication protocols based on the RS-485 standard require some type of arbitration. RS485 is a balanced, differential standard but it is recommended that shielded, twisted pair cable be used to interconnect modules to reduce potential RFI. It is important to maintain the polarity of the two RS485 wires.
Chapter Three Operation Chapter Three 3.1 OPERATION Power-up and Normal Operation When power is initially connected to the 905U-E module, the module will perform internal diagnostics to check its functions. The following table details the status of the indicating LEDs on the front panel under normal operating conditions.
905U-E Wireless Ethernet Bridge User Manual protocol used operates at half-duplex and will operate with the 905U-E without problems. If an application really requires full duplex communications, then the 905U-E should not be used. 3.2 Radio Data 3.3 Addressing A 905U-E network comprises modules with the same "system" address. Only modules with the same system address will communicate with each other. This feature allows more than one system to operate in the same area on the same radio channel. 3.
Chapter Three 3.3 Operation Access Point Access Points (AP)??. Alternatively, Access Points may be used as a single hop repeater. All radio traffic with the radio cell is controlled by the Access Point, and must pass through the Access Point. Ideally the Access Point is placed at the wired location where the majority of data traffic will flow. This will reduce quantity of data transmitted over the radio. Access Points periodically sent out Beacon messages.
905U-E Wireless Ethernet Bridge 3.3 User Manual Radio Rates The 905U-E is capable of using several radio transmission rates. A reduction in speed will increase the range. 3.8 Radio Interference The 905U-E operates on the 902-928MHz license-free radio band (restricted to 915 – 928 MHz in Australia and 921 – 928MHz in New Zealand). Devices on this radio band must use a spread spectrum technique to allow multiple users to share the band with minimal interference.
Chapter Five Chapter Four 4.1 Specifications CONFIGURATION Before Configuring Configuration comprises selecting parameter values for the operation of the 905U-E unit. Before you start configuration, parameter settings must be decided. The main parameters are:• Addressing – System address, IP address, Network mask, Gateway IP address. • Device Mode – Bridge or Router • Operating Mode – Access Point or Client.
905U-E Wireless Ethernet Bridge 4.4 User Manual Factory Default Switch When powered up with the Factory Default switch on, the 905U-E will start with temporary settings of ethernet IP address 192.168.123.123, subnet mask 255.255.255.0, gateway IP 192.168.123.1, username and password “user” and the radio disabled. This allows easy access to configuration when configuration detail has been forgotten. The existing configuration is not modified, unless the user makes changes.
Chapter Five Specifications Select Internet Protocol (TCP/IP) and click on Properties.
905U-E Wireless Ethernet Bridge User Manual On the General tab enter IP address 192.168.123.1, Subnet mask 255.255.255.0, and default gateway 192.168.123.1. Open Internet Explorer and ensure that settings will allow you to connect to the IP address selected. If the PC uses a proxy server, ensure that Internet Explorer will bypass the Proxy Server for local addresses.
Chapter Five Specifications Configuration and Diagnostics may be opened by clicking on any of the menu items, and entering the default username “user” and password “user”. Switch dip-switch on 905U-E to RUN (OFF) position, and cycle power to resume normal configured operation. Option 2 – Set 905UE to same network as PC a) Switch dip-switch on 905U-E to SETUP (ON) position. b) Open a terminal package with 19200bps data rate, 8 data bit, 1 stop and no parity. c) Power up 905U-E.
