Electric shock treatment

If the victim is unconscious Follow the first aid procedures outlined below.

• Lay the victim down on his/her back on a firm surface.

• the neck and tilt the head backwards to free the airway system (Figure 1).

• If needed, open the victim’s mouth and check for breathing.

• If there is no breathing, start artificial respiration without delay (Figure 2) as follows: tilt the head backwards, pinch the nostrils, seal your mouth around the victim’s mouth and give four fast rescue breaths.

• Check for the heartbeat (Figure 3); if there is no heartbeat, begin chest compressions immediately (Figure 4) placing your hands in the centre of the victim’s chest (Figure 5).

• One rescuer: give 2 quick rescue breaths after each 15 compressions.

• Two rescuers: one rescue breath after each 5 compressions.

• Do not stop chest compressions while giving artificial breathing.

• Call for medical help as soon as possible.

If the victim is conscious

• Cover victim with a blanket.
• Try to reassure the victim.
• Loosen the victim’s clothing and have him/her lie down.
• Call for medical help as soon as possible.

Treatment of electric burns

Large burns and broken skin

• Cover affected area with a clean cloth or linen.
• Do not break any blisters that have formed; remove any clothing or fabric that is stuck to the skin; apply adequate ointment.
• Administer adequate treatment for the type of accident.
• Get the victim to a hospital as quickly as possible.
• Elevate arms and legs if injured. If medical help is not available within an hour, the victim is conscious and is not retching, administer a solution of table salt and baking soda (one teaspoon of table salt to half teaspoon of baking soda every 250 ml of water). Have the victim slowly drink half a glass of solution for four times during a period of 15 minutes. Stop at the first sign of retching. Do not administer alcoholic beverages.

Installation and configuration procedure

This section provides a step-by-step description of device installation and configuration procedure. Follow these procedures closely upon first power-on and each time any change is made to general configuration, such as when a new transmission station is added or the equipment is replaced. Once the desired configuration has been set up, no more settings are required for normal operation; at each power-up (even after an accidental shutdown), the device defaults to the parameters set during the initial configuration procedure. The topics covered in this section are discussed at greater length in the next sections, with detailed descriptions of all hardware and firmware features and capabilities. Please see the relevant sections for additional details.

Preparation

Preliminary checks
Unpack the RDMODWEB interface and immediately inspect it for transport damage. Ensure that all connectors are in perfect condition.

Provide for the following (applicable to operating tests and putting into service):

• Connection cable kit including:
• Mains supply, 230 VAC (-15% / +10%), with adequate ground connection;
• Cable for connection of the exciter telemetry signal;
• Ethernet cable (not included) for connection to an ADSL router or LAN network; or
• Crossover Ethernet cable (not included) for connection to an ADSL router or LAN network.

Connections

1. Connect transmitter I2C output to RDMODWEB interface I2C input.

2. Connect the RDMODWEB interface NETWORK output to the relevant input of its ADSL router or LAN network. If your connection equipment is different, identify an equivalent output.
   Note : If you intend to connect it directly to a PC, it is necessary to use a crossover ethernet cable. This is a basic prerequisite to ensure equipment correct operation.

3. Connect the network cable to the relevant MAINS IN connector on RDMODWEB interface.

First Power-On and Set-Up
Perform this procedure upon first power-up and each time you make changes to the configuration this component is integrated into.

Web User Interface (WUI)
Once all connections previously described are performed, the equipment is ready for commissioning. The WUI (Web User Interface) allows you to adjust, modify or display the configuration variables and operation data. Follow the procedure below to open the WUI:

1. Open your web browser on your PC, and connect to http://192.168.0.244 to connect to the WUI (if LAN IP address was previously modified, it is necessary to use the new one). The following page opens:
   Note : If address http://192.168.0.244 does not work, check and set IP address as 192.168.0.XXX (where XXX is a figure between 0 and 255, excluding 244 that is RDMODWEB interface default address). To change the IP address, follow the instructions in the manual or in the online guide and technical help, specific for the Operating System you use.

2. If the User Name and the Password have not been entered and saved yet, and if no changes were made to access modes, enter RVR and RVR to enter as administrator (if access data were modified, enter the new User Name and Password). Then click on Login.
   Note : To enter as user, type user and user into User Name and Password fields. This enables WUI read-only mode.

3. Now interface is ready to remotely read data and modify the various settings of the equipment.

Management Software

1. After access is made, the Main menu (main page) opens and shows possible viewing options. This picture shows the Main menu after access as administrator:
2. If you enter as user, with no administrator privileges, only reading functions will be available within the WUI, and the Main menu will be like this:
   To enter in one of the sub-menus, select the name and then click on item to enter. To go back to MAIN menu, just click on RVR logo at top left of all sub- menus. If user tries to enter a sub-menu with no prior login, or after a certain period of inactivity that can be set and causes automatic logout, upon attempt to enter any of the sub-menus, the following page is displayed:

To enter in one of the sub-menus, select the name and then click on item to enter. To go back to MAIN menu, just click on RVR logo at top left of all sub- menus. If user tries to enter a sub-menu with no prior login, or after a certain period of inactivity that can be set and causes automatic logout, upon attempt to enter any of the sub-menus, the following page is displayed:
