## JSON
Put the `ext_ref_frequency` field into the JSON description if the Kasli is going to use an external frequency:

```json

On peripherals you should choose `"clk_sel": 2` on connected devices.
Peripherals typically should choose `"clk_sel": 2` for MMCX connection and `"clk_sel": 1` for external SMA connection.
Refer to the [official docs](https://m-labs.hk/artiq/manual/core_drivers_reference.html) by searching for `clk_sel`.
You may also need to add `"refclk": <number>` field to the target card.

You may also check fan controls via `fan` commands (see the firmware documentation).
## Test PID
1. For Zotino: connect 10-pins IDC 2.54mm FC cable from internal Thermostat connector to the Zotino TEC
2. General TEC: connect external connector to the TEC
3. Connect Ethernet and PSU
4. Run:
```shell
git clone gitea@git.m-labs.hk:esavkin/thermostat.git
cd thermostat
git checkout zotino-tec
nix develop
python pytec/tec_qt.py
```
5. In `Output Config`, set limits:
* `Max Cooling Current` - 400 mA
* `Max Heating Current` - 400 mA
* `Max Voltage Difference` - 1 V
6. `PID Config` -> `PID Auto Tune` set desired target temperature, which should be slightly above your room temperature (+10C)
7. Set `Thermistor Config` -> `B` and other values, according to the datasheet of the TEC module, for example for Zotino `B` is `3455 K`
8. Run `PID Config` -> `PID Auto Tune` -> `Run` and check graphs that the measured temperature goes to the target temperature,
and eventually stabilizes at +- 0.01 of the target

Fastino uses two physical EEM channels, but in the JSON file there should be only one channel specified,
and it should be the one connected to Fastino's EEM0.
Fastino uses one physical EEM channel, despite having two EEM ports.
