Cable Connectivity for MAPD
The system assembly is provided with a special amphenol connector, or cable,
that is plugged into the back of the ECS at the location occupied by the TN801
(see Figure 13-4). The cable has a female RJ45 receptacle that is used as the
10Base-T Ethernet connection and three DB25 serial connectors. This cable
provides Ethernet access and serial access to the MAPD system.

Cable Connectivity to the MAPD System Assembly
The MAPD Ethernet cable is attached to a “demarcation point” within 25 feet of
the ECS, consisting of a WE-104 terminal block with 2 RJ45 connectors
punched-down back-to-back so as to provide a “straight-through” connection. The
terminal block, in turn, should be attached using suitable 10Base-T category 3 or
better wiring to an Ethernet hub or an Ethernet hub adapter in the host to which
physical connectivity is desired.
