3.2 Configure the Software Switches
The 2-Wire IDSL Line Driver Rack Card features a menu-driven command system
that allows you to configure the local card. The software control port signals of the
ME0001C are carried to each card in the rack along the internal power bus board.
Access to all rack card control ports is provided by a single Managed Micro Rack
Control Module (see the RM262C users’ manual). After setting the control port
address (see
Section 3.1.3
), use the following instructions to configure the unit.
