Figure 9: Top: PXIe acquisition module. Bottom: Front panel of the module.
The front panel of the PXIe acquisition module (Figure 9, bottom) contains the following connectors
and status LEDs:
Four numbered USB-C ports allow connection of up to 4 probes. Interface cables can plug
•
into the USB-C port in either orientation.
An LED next to each USB-C port indicates the status of the respective probe and HS:
•
Off: No clock signal (from a probe) detected. This occurs if the power to the port is not
o
enabled, no probe is plugged into the port, or there is a faulty probe, HS, or cable.
Red: The probe is powered on but not initialized.
o
Green: The probe is powered on and configured. This is the normal status during
o
operation of the probe.
Blinking green: The probe is powered on but not correctly configured.
o
Blue: An internal data emulator on the Artix-7 FPGA is active. The probe data is not used.
o
A general status LED indicates the status of the PXIe module:
•
Off: The Artix-7 FPGA is not powered, or the boot code is not loaded successfully.
o
Red: Error status related to ZYNQ FPGA or PXIe bus.
o
Green: The Artix-7 FPGA is powered on and the boot code is loaded, waiting for a start
o
trigger to start transmitting neural data.
Blue: The Artix-7 FPGA is triggered and is transmitting data to the ZYNQ FPGA.
o
Purple: Combination of red and blue. Data is not read sufficiently fast by the PC. This
o
indicates data loss.
A switch used for remote updates of the Artix-7 and ZYNQ FPGA boot codes.
•
A battery connector to supply power to the probe and HS. The use of this connector is
•
optional. The hardware automatically detects if an external supply is connected and, if so,
switches the port supply from internal system supply to external supply. Connect a 4.0-to-5.0
V battery.
A SYNC/TRIGGER I/O SMA connector:
