8.1 Access the ACE-RIU's internal board
You may wish to access the ACE-RIU internal board to set the gains or provide microphone
power. To access the ACE-RIU internal board, follow these steps:
1. Using a Phillips-head screwdriver, remove the two side screws on the front panel of
the ACE-RIU.
2. Using a 3/16” nut driver, remove the eight jackscrews from the front faceplate.
3. Remove the faceplate with the white printing.
4. Remove the plastic bezel surrounding the faceplate.
5. Slide the black cover off the board.
6. Set the gains or install the resistors as needed.
8.2 Earth-ground the ACE-RIU
ASTi does not require the ACE-RIU to be grounded. However, it was designed to accom-
modate customers with strict grounding policies and requirements. To reduce resistance, keep
your grounding wire as short as possible. This practice effectively dissipates an unwanted
electrical charge.
