DATA
These indicators turn green when any data activity is present. An active DATA 1 TX LED
indicates Manchester data is present at the input terminals of the MTX-8823C-SL. An active
DATA 2 TX or RX LED indicates RS232 data is present at the input / output terminals of the
MTX-8823C-SL. The intensity of these indicators will vary depending on the input / output data
patterns sent to the unit. The data activity associated with these front panel DATA LEDs are
summarized below.
