14.2 Physical Description
The CDI-70 data interface is implemented on a 3.95 x 7.022 inch (10.03 x 17.83 cm) PCB.
Connectivity to the CDM-710G is implemented with a 96-pin DIN receptacle. The LAN interface
consists of a single IEEE 802.3ab 1000 Base-T copper-compliant female RJ-45 connector – refer
to Sect. 14.3 for the connector pinout. This connector features Light-Emitting Diode (LED)
indicators for Link Status and Link Activity.
Figure 14-2 shows a block diagram for the CDI-70 interface.
