Q: I've purchased an ADAS1000 evaluation board, the EVAL-ADAS1000SDZ and I need to know how to connect my patient simulator to the board?
A: As documented in the User Guide, UG-426, the ADAS1000 evaluation board uses a standard DB15 connector with the the following pinout

- Make your own cable
- The actual component used on the board is a female DB15 component is a Tyco Electronics 1-1634585-2 or similar.
- The mating component would be a male DB15 plug, something like 5-747908-2 from TE Connectivity or similar
- Source a manufacturer standard patient cable with same pinout
- there are various manufacturers cables available from medical suppliers, you will need to review the pinout of the cable to ensure a match.
- when selecting an off the shelf cable, beaware of the impedance of the cable. If you intend to evaluate respiration, then the impedance of the cable should be kept <5kohms, ideally as low as possible.
