+
+## 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
