Other characteristics and features.
-
Internal warning signal indicating a failure in one of the power supplies. If a failure occurs, the
“ALARM” LED on the BC2240 controller board will light up.
-
Power feed circuit designed to support hot-swapping operations.
-
Digital adjustment of digital gain (±12 dB) in the 8 inputs and the 8 outputs.
Programming jumpers.
This board has a series of internal programming jumpers (PJ). However, these jumpers are
configured at the factory and, in normal operation, do not need to be changed.
Firmware modules.
At the firmware level, this board is made up of the following modules:
-
PIC microcontroller: manages board communications and start-up.
-
FPGA programmable device: manages the converters and the TDM bus.
The firmware versions can be brought up to date by using the “BC2000D Firmware Upgrade“
software application.
