4. INTERFACES ON OFFER

4.1. Detection & generation

The toolkit has a total of eight digital lines or channels. Four digital input lines are used for

detecting events that occur on a remote PC. Four further lines are used by the toolkit host

to feed simulated responses into the remote PC as if they had been made by a human.

When making use of the BBTK response pad the four output lines are switched to input

mode giving a total of eight digital input lines. Four continue to offer support for the

standard sensors or TTL inputs while the additional four monitor each button of the

response pad. An overview of the toolkit interfaces is shown overleaf.
