```

|
||||
## 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
|
||||
|
||||
### Output
|
||||
|
||||
```text
|
||||
*** Testing TTL outputs.
|
||||
Outputs are tested in groups of 4. Touch each TTL connector
|
||||
with the oscilloscope probe tip, and check that the number of
|
||||
pulses corresponds to its number in the group.
|
||||
Press ENTER when done.
|
||||
Testing TTL outputs: ttl0, ttl1, ttl2, ttl3.
|
||||
```
|
||||
|
||||
1. Touch each TTL connector with the oscilloscope probe tip
|
||||
2. Adjust time- and voltage- scale and trigger threshold so that you clearly see square pulse
|
||||
3. Check that first TTL connector outputs 1 pulse, second - 2... fourth - 4 pulses
|
||||
4. Repeat 1-3 for each group of TTL connectors
|
||||
|
||||
### Input
|
||||
|
||||
```text
|
||||
*** Testing TTL inputs.
|
||||
TTL device to use as stimulus (default: ttl4): ttl4
|
||||
Connect ttl4 to ttl0. Press ENTER when done.
|
||||
...
|
||||
```
|
||||
|
||||
1. Mount a wire with respective connector to the chosen TTL output (any should work, choose most convenient one)
|
||||
2. Connect the end of the wire to the TTL input requested by the `artiq_sinara_test` (you may use fast connector for SMA)
|
||||
3. Press ENTER and check that `artiq_sinara_test` prints `PASSED`
|
||||
4. Repeat 2-3 for every connector
