Enter the IP address of the ProtoBase computer in the Sales32c.INI file on all salespoints. This must be done in the local Sales32c.INI file – not within the global .INI in SysManager > Preferences > Miscellaneous > Global INI. Browse to the Sales32c.INI file. The default location of this file is C:\ProgramData\Siriusware\Sales\Sales32c.INI, but you can also get to it from Windows Start > All Programs > Siriusware > Settings. In the [Server] section there is an entry for Protobase=. Enter the IP address of the ProtoBase server followed by the port (default is 4209). If the IP address for the ProtoBase server is set in the SiteDefaults.INI file, this setting is automatically assigned when you install Sales on a salespoint. Make sure that the CreditCardSales setting is set to TRUE. Without this set to TRUE, cards are not processed for authorizations when used for payment. This setting can also be automatically assigned when you install Sales.
