GTW are no not blocked and allow at least 50 mm free air-space at 
each side of the unit. The ASI-IP-GTW is designed to be stacked in 
19"racks without ventilation panels between. In systems with 
stacked units, it may be required to use forced-air cooling to reduce 
the operating ambient temperature. 
Figure 4 shows the air path through the unit.

To connect the equipment 

Once the ASI-IP-GTW is installed in its intended operating position, it is 
ready to be connected to the rest of the system. The following figure 
shows the different equipment connections.

Remove mains supply previous to move or install the equipment. 
Ensure ESD precautions are observed whilst interconnecting 
equipment.

ASI port 

The ASI-IP-GTW can be operated in three modes: IP Transmit, IP 
Receive, and IP bi-directional mode.  
In IP transmit mode, the equipment receives up to 8 DVB-ASI streams 
and sends them to the IP network. In this mode, connect the individual 
DVB-ASI input signals to the connectors marked with ASI. If you have 
ordered the unit with less than 4 ASI ports, the enabled ports starts at 
number 1 up to the number of ports ordered. 
In IP receive mode, the equipment receives an IP stream and sends the 
individual MPEG-2 transport streams out on the DVB-ASI connectors. 
In this mode, connect the DVB-ASI output to the input of the 
equipment to receive MEG-2 transport stream from the unit. If you
