OPERATION
Front Panel Controls/Displays
The front panel, shown below, has three distinct functional areas - the Indicator LED’s
under the OctaStream logo on the right side; the switch controls, mostly on the left side and
the 7-segment display in the middle.
INDICATOR LED’S
LED’s are visible from the exterior of the frame when the front door is installed to accom-
modate checking the status of the modules without affecting the operating conditions within
the frame. The LED’s provide information about the status of three operating conditions -
error status, OctaBus™ status and power bus status.
1. ERROR - When this red LED is illuminated an invalid operating condition exists
within the DA5315. These errors fall into three categories - power-on self-test
failure, missing inputs or problems with the OctaBus™.
a.
Power-On Errors - cycle the power to the unit. It is recommended that the unit
be left unpowered for a minimum of 5 seconds before reinitializing to allow all
residual power to drain from the circuits assuring a complete reset of all
functions.
b.
Missing Inputs - The Error LED will illuminate when either the input specified
for a given output is unavailable or the defined reference signal is not
present. To relieve this condition for unused ouputs, disable output error
reporting using the menu selection under the main menu item.
c.
OctaBus™ - If there are problems with the signal on the OctaBus the ERROR
LED will be illuminated and error messages can be accessed via the
Diagnostic menu.
2. OCTABUS - This green LED indicates the presence of a valid signal connected to
the OctaBus™ input BNC.
3. POWER - This green LED indicates the presence of suitable power being supplied
to the module by the power supply in the S5000 frame.
