Current Version: 2.33 The PCONNECTCE/U upgrade is for customers who have previously purchased PConnectCE software. The PDA-to-RS232 cable (available as of the 2.0 version) is included in the upgrade. Inclusion of the connector allows a customer who purchases an upgrade from 1.X to 2.0 to have all of the items that are included in a full PConnect (non-upgrade) 2.0 package.
