Serial Configuration Port Connection
On the 2000T3 frame, the female DB9 connector J101 is used to connect a
computer running terminal emulation to initially configure the frame for
networking. The 2000NET Network Interface Module is required to
support this connection. In the 2000T1 frame, the RJ-45 connector on the
front of the 2000NET is used for this function. Refer to the 2000NET
Network Interface Module Instruction Manual for details.
