Monitor and Control
Each IBUC is equipped with extensive monitor and control (M&C) capabilities. Use
any of the following methods to access those capabilities:
• Via the J2 connector using RS232. This method requires that a separate cable must
be run and connected to J2.
Figure D.1 on page D-2 contains a drawing for fabricating your own cable.
• Via the J4 connector using TCP/IP. This method requires a separate Ethernet
cable.
Figure D.2 on page D-3 contains a drawing for fabricating your own cable.
