    5 LED Indicators 5.1 General The MicroPAQ-940S includes various LED indications. Almost all of the LEDs are high brightness red, except for the Comm Port TXD Leds (Green). The Status LEDs are visible through the front panel. Some other LEDs are visible are located on the PCB, behind the front panel or at the edges, and cannot easily be viewed without removing the front panel.

    6 Dip Switches 6.1 Address DIP Switches Each MicroPAQ-940S is addressable (from the MicroPAQ-940P) via eight DIP switches located in the upper left hand corner. Address is in Binary, with Bit 0 on the left, and Bit 8 on the right. A switch in the UP position is a logic “1” and DOWN is a logic “0”.
