APPENDIX D - ACT3 RS232C INTERFACE CONNECTIONS
The ACT-3 has a DB9S connector configured as Data Communication Equipment (DCE). The
following connection details are for use with IBM™ PC compatible computers. Connections are
given for both 9 pin and 25 pin connectors. Note that some computers have the 25-pin connector
configured as DTE while others have it connected as DCE. The information given here is for a DTE
configuration which is the more common. On a standard PC, a NULL Modem cable will work fine.
Communications are at the preset Baud Rate, 8 bits, No Parity and 1 stop bit.
