Each option module derives power from the base TSU/
TDU/ESU unit. Power to the base unit is supplied by a
captive eight-foot power cord.

board to the option module. Perform the following steps
to install the plug-on board:
1. Hold the plug-on board above the option module.
2. Using a downward and right-to-left motion, slip the
plug-on board connector into opening in the option
module back panel.
3. Moving the plug-on board downward, secure the
connection of the header pins at the front of the
boards.
4. Install two 4-40 screws at both front edges of the
option module.
5. Install two 4-40 screws on each of the standoffs on
the rear of the plug-on module.
