MiniDAQ usage

Note

The MiniDAQ configuration steps are only needed after a power cycle or power outage.

Load a firmware file

This is temporary, as MiniDAQ will reprogram itself with the firmware stored on the on-board flash memory.

To load a firmware:

pcie40_pgm ~/src/sof_files/lhcb_daq_firmware_readout40_pcie40v1_minidaq_forUT_Bologna+realsim_12+12links_unset_090620.sof

In our MiniDAQ server, all sof firmware are located in:

$HOME/src/sof_files

After programming the MiniDAQ FPGA, restart (not power cycle) the server, and follow these steps:

Open a terminal, type in:
```
pcie40_reload -m
config_fPLL.py
```
Start the Project by going to going to Applications, WinCC, Project Administrator.
From the top menu, click JCOP Framework, then Device Editor and Navigator, then FSM. Now expand dist_1, then right click on MiniDAQ to open the TOP panel.
Take the MiniDAQ. Click the MiniDAQ state (it now should be Not Configured), then click Configure.
If not all devices showing as Ready (excluding DATAFLOW), repeat 2-3.

If you are in UMD network, use a VNC client and the address are:

<minidaq_ip_addr>:5900

If you are outside, first create a SSH tunnel to map MiniDAQ port 5900 to one of your localhost port (5901 in the example):

SSH -L 5901:localhost:5900 <user>@<minidaq_ip_addr>

Then use the local port for your VNC session:

localhost:5901

Note

The additional password for the VNC connection is printed on the sticker of the Windows PC.

Info

If you are a Linux user, install tigervnc and follow the standard literature on the Internet on how to use it.

If you are a macOS user, use the mighty built-in VNC viewer from cli:

open vnc://<ip_addr>:<port>

A series of command-line scripts have been implemented in nanoDAQ. The commands are explained in the nanoDAQ wiki.

Please refer to this guide on how to configure a MiniDAQ from scratch.
