Cadacus WCF Service Download and Installation


Our Cadacus WCF (Windows Communication Foundation) Service is based on a Microsoft framework for communicating messages between our Handheld WMS solution and the SYSPRO application server. The Cadacus WCF service "listens" for messages sent from any Handheld WMS solution endpoint, facilitates processing of the messages with the SYSPRO application server, and properly returns the requested response to each endpoint.

This version also features "queued posting", which provides the following benefits:

  • improved performance:  transaction queues provide load leveling to prevent sending applications (handheld devices) from overwhelming the receiving application (SYSPRO) during peak work loads
  • failure isolation:  sending and receiving applications can fail without affecting each other
  • disconnected operations:  in some limited availability networks where mobile devices might move in- and out-of range in a wireless network, message queuing allows connections to drop and be re-established without interrupting the worker's task at hand

Steps for installation:

Requirement:  To use this version of Cadacus WCF Service, the minimum version of Microsoft .NET Framework (4.5.2, or greater) must be installed. Most modern Windows servers manage this requirement without manual intervention; however, if there is a question as to which version is installed, please contact your IT department to verify this minimum version is met.
  1. Click the download button below and save the installation file.  Then navigate to it and run the installation program "as Administrator" (required) on the SYSPRO application server (example below).  Follow the prompts of the installation program.
