Front Panel Configuration Port
f Configuration port — This 2.5 mm port (jack) can be used to configure the SMX
during setup via RS-232, and has an independent protocol from the primary RS-232
port on the rear panel. Use the 2.5 mm configuration cable, part number
70-335-01
(see figure 9) for connection to your PC serial port.
RS-232 protocol (default): 9600 baud, 1 stop bit, no parity, 8 data bits, no flow control.

Powering Up
When power is applied to the SMX, it undergoes a start-up self testing sequence:
1. All buttons flash green, red, and then amber, before extinguishing.
NOTE: The order in which the colors are displayed may vary.
2. The two LEDs light green to indicate power is present to the main unit and I/O boards.
NOTE: This sequence also occurs when the unit restarts after firmware uploads.
Front Panel Operation
This section covers basic setup and configuration of the SMX using the front panel.
Ties — General Information
• During any operation of front panel buttons, any active input, output, and control
buttons stay lit or blink for 30 seconds. If, during that 30 seconds, no button is pressed,
a time-out occurs and all buttons go out. The operation must be restarted.
• To enable any selected input signal to be viewed on a display device, the input must be
tied to an output on the same plane.
• An output can be tied to one input only, but an input can have multiple outputs.
• If an input with no existing tie is selected, only that input button lights when pressed. No
output buttons light.
• When a plane and an input are selected, the associated output buttons flash the
appropriate color to indicate tentative ties. Buttons for outputs to the selected input light
steadily in the appropriate color.
• If a tie is made between an input and an output and the selected output was previously
tied to another input, the older tie is broken when the Enter button is pressed.
