Slide the MT109-100 into an available slot in the MultiTasker in order to connect to the bus. Make sure that the MT109-100 fits into place and then
secure the card by tightening the retainer screws located on the top and bottom of the card. Identify the slot number and note that it is for RS-232
control.

Restore power to the MultiTasker system.
Step 5.
The LED on the card panel will turn red indicating the card is operational.
