2.6 Connection to the data network
The selected network interface must be connected to the transmission equip-
ment in accordance with the interface pin assignment (see SECTION 1.5.3).
Several network interfaces can be connected simultaneously, but only one in-
terface can be active at a given time. The activation of the network interfaces
is controlled by software.
The X.21 interfaces nos. 4, 5 and 6 can be accessed at the TS16 interface and
the RS449 interface using the adapter cables which are included in the deli-
very.
2.7 Connection to the operator interfaces
Four operator interfaces have been provided for the control of the TITAN vi-
deocodec.
The pin assignments are shown in SECTION 1.5.5.
2.8 Connection to the mains voltage
The TITAN videocodec can be operated with an AC voltage (mains) between
90 and 253 V without the need for switching. The mains frequency can vary
between 45 Hz and 65 Hz. The housing must be earthed (grounded) in accor-
dance with local regulations. This earthing is usually realised via the protective
conductor (green/yellow) of the mains cable. If the mains cable does not have
a protective conductor, however, the device must be earthed via the earthing
bolt (see FIGURE 2.1).
Warning Use the mains cable provided! Do not use an extension cable
without a protective conductor! If in doubt, use additional GND!
2.9 Opening the device
Warning The mains plug must be removed before the device is opened!
Although a large part of the system configuration can be carried out from the
outside using software, it can sometimes become necessary to open the de-
vice. To do this, remove the four screws on the front panel. The panel can now
be pulled out by the handles. The keypad/display unit can also be removed.
The individual plug-in units are inserted horizontally and can easily be remo-
ved or inserted using the lever provided.
Warning Dangerously high voltages can still be present on the power
supply even several minutes after it has been disconnected
from the mains. Do not, therefore, touch any component or
soldering point on the power supply!
The equipping of the system is shown in the table in SECTION 1.4.
To re-assemble the unit, carry out the above steps in reverse order.
