The S3 timer is capable of sending data from either the Printer or Scoreboard port. ALways use the Printer port first because data is sent out of both possible connections. The Scoreboard port only sends "time of day" in one connection. Experiment after you have made the connection using the Printer port. Label the DIN plug "UP" or similar.
Likewise the TDc 4000 is direction specific. If it does not work in one direction, reverse the plug.
