10.2 Physical Description
The CDI-70 1000 Base-T Gigabit Ethernet (GigE) Interface is implemented on a 3.95 x 7.022
inch (10.03 x 17.83 cm) PCB. Connectivity to the CDM-710 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. 10.3 for the connector pinout. This connector features Light-
Emitting Diode (LED) indicators for Link Status and Link Activity.
Figure 10-2 shows a block diagram for the CDI-70 interface.
