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 condition 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 UDC-3G-XMUX4 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 through 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
built-in frame-synchronizer, see chapter 3.1.1.
