Known Bittware Configurations

Tom Eichlersmith edited this page Dec 5, 2025 · 1 revision

Most test stands only have one Bittware, so that Bittware is at /dev/datadev_0.

The DAQ server has three Bittwares.

Location Subsystem
/dev/datadev_0 Tracker
/dev/datadev_1 Ecal
/dev/datadev_2 Hcal

Each Bittware has up to four links we can connect to. A few examples helps clarify this.

Link 1 on Ecal Bittware (connected to Ecal Layer 1)

./pflpgbt --bw 1 /dev/datadev_1

Link 0 on Hcal Bittware (connected to HcalBackplane)

./pflpgbt --bw 0 /dev/datadev_2

Link 0 on Zero'th Bittware (/dev/datadev_0 is the default, only works on test stands)

./pflpgbt --bw 0
