SDM-9000 Satellite Modem

2.4 External Connectors

When a breakout panel is not required, the external modem connections between the
modem and other equipment are made through several rear panel connectors. These
connectors are shown in Figure 2-2, and their locations are listed in Table 2-1. The
connectors are described in the following paragraphs.
When a B141-1 breakout panel is required, refer to the B141-1 Breakout Panel
Installation and Operation Manual for connector information.
Note: In order to meet the European EMC Directive (EN55022, EN50082-1), properly
shielded cables for DATA I/O are required. These cables must be double-shielded from
end to end, ensuring a continuous ground shield.
