AHFBA404 is a PCI-express Gen2 4 lane card to fit standard PC enclosure On the front panel: 4xSFP marked A,B,C,D
AFHBA404 is used to connect 1 to 4 ACQ2106 units to a HOST PC, establishing a fiber-optic link that may be used in one of two ways:
Data is transferred in large blocks at maximum 400MB/s per link. (max 4MB, min 4K), typically to disk archive.
In theory it's possible to run all 4 links at full speed, but to date D-TACQ has not tested a PC that is capable of handling this.
More typical usage:
- 1 x 400MB/s, single box, full rate to local disk (NVMe SSD recommended)
- 4 x 100MB/s, connect 4 x ACQ2106 to single host.
AFHBA404 may also be used to send a common trigger to multiple ACQ2106.
See README.ACQ2106.HTS and STREAM/ for details.
Classic Plasma Control System. Data is transferred in "small" blocks, one sample at a time to HOST DRAM with minimum latency. An LLC system can be implemented in one or multiple ACQ2106 boxes.
Typical use case:
- ACQ2106+4xACQ424ELF-32+2xAO424ELF32 : 128AI, 64AO, run in an LLC loop at 100kSPS.
For modern use of LLC, see ACQPROC-README

If your AFHBA404 or ACQ2106 does NOT meet the requirements, please contact D-TACQ for support.

Linux Device numbers 0,1,2,3 map to local ports A,B,C,D brotto 0 acq2106_110 A hostname: brotto (the HOST PC) DEVNUM : 0 (localport A) UUT : acq2106_110 (remote host name) RPORT : A (remote port A) NB: the LINK is used for DATA only. Control is via Gigabit Ethernet
Ideally, the HOSTPC has a DNS system (/etc/hosts if no DNS) that will allow network software to connect to the UUT by name.
