using the DIP switches. Place MST 488-27 power module controller with the top of the unit fac-
ing you, front panel to the right. The Device Address DIP switches are positions 1 through 5
(from right to left, see Figure 2-1).

• Echo: Sw Pos 3 (1 = enable, 0 = disable)
• XON: Sw Pos 2 (1 = disable, 0 = enable)
