Table 2: LED states and what they mean
2.3.1 Exceptions/special conditions for the LEDS
The locate command will make all four LEDs blink on and off synchronously to quickly identify
the module in a larger installation. The operation of the card is not otherwise affected by the
command, only the appearance of the LEDs will change. The LEDs will return to their normal
states and functions after the special locate condition times out.
FPGA firmware upgrades will activate running lights after the firmware download has finished.
Do not remove power to the card when running lights are active, the card is unpacking and
installing the new firmware. The SPG-AVA-DMUX will automatically reboot after a successful
upgrade, and the LEDs will then also return to their normal functions.
2.4 Selecting between Gyda mode or Manual mode
The board can be configured either manually or via the system controller Multicon GYDA.
Since there’s a limited number of switches available compared to the total number of settings
available for the module, only a subset of the parameters can be adjusted when operating in
manual mode. Generally, the parameters that cannot be directly controlled by the DIP
switches will take their settings from the previous Multicon GYDA session. This means that
for a specific manual setup it may be necessary to configure the module with a Multicon
GYDA before switching to manual mode.
To reach manual mode, the lower DIP (labelled OVR) on the module must be switched to the
“On” position (to the right) and the board must be re-booted. This isolates the board from
Multicon GYDA control, but the module will still accept commands to retrieve its status, and
also the commands necessary to initiate and perform firmware upgrades.
In addition to the DIP switches, manual mode will also activate the rotary switch and the two
push-buttons at the front of the module. These are used to control the phase delay for the
sync-pulse generator.
