Sinara 5432 DAC Zotino / Sinara 5632 DAC Fastino

JSON

{
  "type": "zotino",
  "ports": [<port num>]
}

{
  "type": "fastino",
  "hw_rev": "v1.2", // optional
  "ports": [<port num>]
}

Fastino uses one physical EEM channel, despite having two EEM ports.

Setup

Connect the BNC/SMA-IDC adapters to the Zotino/Fastino with 26-pin cable if needed by customer. Be aware of the ports order - see reference numbers on the board.

Testing

After running artiq_sinara_test:

*** Testing Zotino DACs and USER LEDs.
Voltages:
zotino0 0.1 -0.1 0.2 -0.2 0.3 -0.3 0.4 -0.4 0.5 -0.5 0.6 -0.6 0.7 -0.7 0.8 -0.8 0.9 -0.9 1.0 -1.0 1.1 -1.1 1.2 -1.2 1.3 -1.3 1.4 -1.4 1.5 -1.5 1.6 -1.6
Press ENTER when done.

*** Testing Fastino DACs and USER LEDs.
Voltages:
fastino0 0.1 -0.1 0.2 -0.2 0.3 -0.3 0.4 -0.4 0.5 -0.5 0.6 -0.6 0.7 -0.7 0.8 -0.8 0.9 -0.9 1.0 -1.0 1.1 -1.1 1.2 -1.2 1.3 -1.3 1.4 -1.4 1.5 -1.5 1.6 -1.6
Press ENTER when done.

Touch with multimeter/DC voltmeter each pair of pins from bottom to top (left pins are ground)
Check that respective pins have voltages as described by artiq_sinara_test
If there are BNC/SMA-IDC adapters, also check their voltages - they should be the same
Check LEDs are on

Common problems

High-freq audible noise and output values all near -0.1 on Zotino v1.4.2

This may happen when power-cycle is too short. Power down the crate, wait at least 30 seconds, and power up again. Issue.

Zero/meaningless voltage output on Fastino

Some Fastino may not output any meaningful voltage during testing, usually that means it has no gateware flashed.

Another common symptom of no gateware is that no LEDs are lit up. Whereas if the gateware has been flashed, the PG and FD LEDs will be lit green.

You can flash the gateware with a Kasli/Kasli-SoC, be it in the crate or standalone (no specific gateware needed for Kasli/SoC):

Download the latest fastino.bin release from quartiq/fastino.
Run git clone https://github.com/quartiq/kasli-i2c.git and place fastino.bin in the kasli-i2c directory.
Connect the Fastino's EEM0 to any available Kasli/Kasli-SoC EEM port (do not hot-plug). You may skip this step if Fastino is connected within a crate.
Power on the standalone Kasli/Kasli-SoC and connect it to the PC via data micro-USB.
Run nix-shell -p python311Packages.pyftdi.
Run cd kasli-i2c; python flash_fastino.py 0 EEM<number> write fastino.bin where <number> is the EEM port number on the Kasli/Kasli-SoC side.
If PG and FD LEDs are lit green, the Fastino is ready.

Fastino output is 10V

Fastinos by default after power up output 10V on all channels if not driven by the test otherwise. Make sure the EEM ports are specified correctly in the JSON and the EEM cable is connected to EEM0 on the Fastino.
