Using Front Panel Modes

he RFI-9256 has a unique front panel user interface that can be used to assess the Radio performance

without any additional test equipment. A picture of the front panel is shown in Figure 5-1 below. The

interface is controlled by means of a small push button switch located on the front panel. A dual colour

LED bar graph display is used to signal various settings to the user.

When the Modem is first turned on the display defaults to Mode 1. The Operational Mode is

numbered down the left-hand side of the LED Display. In this mode, the purpose of each LED is

indicated in the first column on the front panel (under the heading Mode 1), for example the top-most

LED indicates the status of the Network Link. If the switch is pressed the display will change and indicate

the current mode of operation by a RED LED. If the switch is held down longer than 1 second the Mode

LED indicator will begin cycling through each mode. While the unit is in this cycling operation, the rate at

which the mode selection cycles can be increased by pressing the button at a faster rate than the automatic

toggle. Once the desired operational mode is reached then the switch can be released and after

approximately one second delay the LED display will indicate the function for that mode.

Details of the scale for Mode 2 (the receive signal power indicator mode) and Mode 3 (the transmit

power indicator mode) are also included on the front panel, under the respective headings.

Mode 1

The LED indicators in Mode 1 show the general flow of data and other radio characteristics. Table 5-1

describes the front panel indicators in Mode 1.
