Cleaning fiber-optic connectors
WARNING
Never clean an optical connector attached to a fiber that is carrying light.
Particles of foreign matter on the tip of a ferrule can have a disabling effect on fiber-optic transmission. Fiber-optic connectors need to be cleaned every time they are mated and unmated; it is essential that fiber-optic users develop the necessary discipline to always clean the connectors before they are mated.
Use a commerially available cleaning kit specifically designed for fiber-optic connectors and follow the manufacturer's instructions carefully.
•The connector sections to be cleaned include the tips and sides of ferrules, the interior walls of alignment sleeves, and the interior and exterior of connector shells.
•For plugs, the interior surfaces of alignment sleeves and the tips of ferrules are to be cleaned with a cleaning stick treated with the appropriate fluid. (Cleaning sticks with a slender design are available that allow alignment sleeves to be cleaned without having to detach them.)
•For jacks, it is important to clean both the tips and sides of the completely protruding ferrules.
•Both the male and female connector shells tend to attract dust and metal particles, so it is important to clean both the insides and outsides.
•The fiber end face and ferrule must be absolutely clean before it is inserted into a transmitter or receiver.
•Mate the connector immediately! Don't let the connector lie around and collect dust before mating.
•Air can be used to remove lint or loose dust from the port of a transmitter or receiver to be mated with the connector. Never insert any liquid into the ports.

Base station earthing
The rear of the base station power supply unit has two separate screw terminals for protective earth 
(PE) and video earth 
(VE). These are normally connected by a metal strap.
Metal strap
PE VE
The protective earth terminal is internally connected to the protective earth conductor of the power cable. In normal circumstances the connection between the protective earth and the video earth should not be broken. If required, the central earth connection wire of the studio can be connected to terminal PE in accordance with VDE regulation 0800/part2.
Only if the studio (or OB van) is equipped with separate protective and video earth systems may the metal strap be removed. Under these circumstances the video earth terminal must be connected to the central functional earth potential (video earth) of the studio. This earth potential should have functional protective and noiseless earth (FPE) qualities as stated in the VDE regulation 0800/part2. A low impedance interconnection of both earth conductors must be provided at the central studio earthing point.
Mains lead wiring for UK users
The wires in the mains lead are colored in accordance with the following code:
GREEN and YELLOWEARTH
BLUENEUTRAL
BROWNLIVE
As the colors of the wires in the mains lead of this apparatus may not correspond with the colored markings identifying the terminals in your plug proceed as follows:
•The wire colored GREEN AND YELLOW must be connected to the terminal on the plug
marked with the letter E or by the safety earth symbol 
or colored GREEN or GREEN AND YELLOW.
•The wire colored BROWN must be connected to the terminal marked with the letter L or colored RED.
•The wire colored BLUE must be connected to the terminal marked with the letter N or colored BLACK.
Ensure that your equipment is connected correctly - if you are in any doubt consult a qualified electrician.

Transmission quality can be precisely monitored before and during operation right from the OCP 400 operational control panel.
1.2.2 Dockable adapter
The dockable principle allows a choice of transmission and thus the greatest flexibility and cost-effective solutions in multiple applications.
1.2.3 Base station
The base station is only 2U high yet offers full broadcast functionality and quality. The low height means that rack space is saved. Its low power consumption and efficient internal cooling eliminate the need for space between adjacent units. Sliding rails are additionally available for easy access to the back panel. The wings on either side of the back panel protect all connectors from damage, including the Fiber connector. The Fiber connector itself can easily be mounted at different angles to suit all mounting requirements.
1.2.4 Operational controls
You can access the base station menu, which contains all operational settings, from an Operational Control Panel. In addition to the operational menu, the installation and service menus can be activated from the base station by pressing a switch behind the front panel. The base station is compatible with all existing control system components.
An OCP 400 operational control panel can be connected directly to the base station using a cross-over Ethernet cable.
Full camera control is provided via a C2IP Ethernet-based control network.
1.2.5 Intercom
The communication facilities provide for two-wire or four-wire high quality intercom signals.

Base station
2.1Installation
2.1.1 Control bus
The base station is connected to the control network hub or router via an Ethernet cable (straight-through, not cross-over). An OCP (Operational Control Panel) and, if required an MCP (Master Control Panel), are also connected to the Ethernet network via a hub or router. An OCP can also be connected directly to the base station using a cross-over Ethernet cable.
The IP address and other options for the Ethernet connection can be set up in the basestation system menu. These items can also be set up remotely using a network configuration tool such as Grass Valley’s SiteConfig.
Note
By default, the Ethernet connection is set up for automatic IP configuration.
2.1.2Intercom cabling
Connect the studio intercom system to the rear of the base station. The wiring of the panel connector is shown below for two-wire and four-wire systems.

Note
When accessed from the OCP, the user level is set to Operator.
2.2.3Menu navigation
The base station menu is used for configuring the base station. As there are a large number of functions and set-up options available, it may require some time to become familiar with them all. The menu video signal is available on the Monitoring and CVBS+Text outputs.
Entering the menu
Use the rotary/push button at the front of the base station or the Operational Control Panel to access the base station menu. The functions of the base station are grouped into menus and sub-menus. When accessed, the main menu appears on the monitor.

The main menu screen shows five items and the name of the menu. One or more item can be hidden but become visible when you scroll down. A cursor shows your position in the menu. The navigation buttons (rotary/push button or OCP buttons) move the cursor up and down.
Finding your way
Use navigation buttons to move the cursor through the menu items. If a double arrow (>>) is visible, then pressing the rotary/push button or the SELECT button brings you one level lower in the menu system. Only five items are visible in each menu. Scroll up or down to see more items.
When you first enter a menu (other than the main menu) the cursor is positioned next to the first item. The TOP and PREVIOUS entries are not immediately visible but are located above the first item. Use the control to scroll up to them.

The SYSTEM menu above shows the items displayed when you first enter the menu and the other items that are available by scrolling up or down.
Leaving the menu
If you are deep within the menu structure, follow these steps to leave:
•If necessary move the cursor to the left most column.
•Scroll upwards until the cursor points to TOP (this is the main menu).
•Press the rotary/push button or the SELECT button on the OCP. The cursor now points to the Menu off item of the MAIN menu.
•Press the rotary/push button or the SELECT button on the OCP to leave the system menu.
This is the recommended way of leaving the system menu. The menu system disappears after a few seconds when you stop navigating. This delay can be set in the MONITORING > MENU
menu. However, when you enter the system menu again you enter at the last position of the cursor and not at the top of main menu. To prevent confusion the next time you enter the system menu, it is advisable to leave the system menu by returning to the main menu (TOP) and selecting MENU OFF.
Making changes
To find out where to change a function, consult “Base station menu” on page 47to find out under which menu group or subgroup the function is located. If the cursor points to an item (and there are no double arrows to indicate a sub-menu) then the item pointed to has a value. The value can be:
•a toggle value (only two values)
•a list value (more than two values)
•an analogue value (variable from 00 to 99)
•or unavailable (---).
If the value is unavailable it cannot be changed. This is indicated by three dashes (---). This can occur, for example, when a function is switched off. The analogue values associated with that function are then unavailable. If there are only two values associated with the function, then
