Dual Ethernet LAN Port
The optional P190 second Ethernet port on the S600 is for high-speed
communications using an Ethernet Local Area Network (LAN)
architecture. The speed of data transfer is 10M bps when using
10BaseT twisted pair cable.
Note
:
, for information on
the standard Ethernet port.
The P190 Dual Ethernet communications port is comprised of a
mezzanine card and a port backplate with a FCC-68 RJ-45 connector.
Refer to Figure 3-5.
The mezzanine card plugs into the PC/104 slot on the P152 CPU
board.
