# JSON

```json
[
    {
        "type": "dio",
        "board": "DIO_MCX",
        "ports": [0],
        "edge_counter": true, // optional
        "bank_direction_low": "input",
        "bank_direction_high": "output"
    },
    {
        "type": "dio",
        "board": "DIO_MCX",
        "ports": [1],
        "bank_direction_low": "output",
        "bank_direction_high": "output"
    }
]
```

Since MCX TTL has twice as much as BNC/SMA cards, it is treated as two cards - there are 2 ports to be connected
and 2 entries in the JSON.

## Setup

Switch the direction switches (shown on the picture below) according to customer requests.
Remember, that you can only switch directions in groups of four.

## Test

Refer to the [BNC/SMA TTL instructions](bnc_sma_ttl.md) for testing, but chose appropriate connector, 
and respect increased number of channels.
