POWER switch: T urns the power on/off. Flip up to turn the power on; flip down to turn the
power off. After turning on the power, all status LEDs light for about 20 seconds. Then all
LEDs except POWER go off about 10 seconds later. Turn on the IB-281 about 30 seconds after turning on the IB-681, otherwise the IB-281 may display “HSD Fault.” If the FAIL
lamp on the IB-281 goes off then operation is normal.
DIMMER control: Adjusts the illumination of the status LEDs.
Switch panel: Contains eight DIP switches and the Data Rate switch which set operation
parameters. See page 3 for details.
Status LEDs: Show equipment status.
POWER: Lights when the power is turned on.
SYNC: Lights, during HSD communications, when satellite signal becomes synchro-
nized.
TX (64K): Lights when data rate is 64 Kbps.
TX (56K): Lights when data rate is 56 Kbps.
FAIL: Lights for communication error.
Note: TX LED on IB-281 dose not light during HSD communications.
