Initiate HEM/IngEstate Message (Tran Type 36-07)

note

HEM and IngEstate are Ingenico PIN Pad management systems implemented by Elavon. Simplify is currently transitioning from the use of IngEstate to HEM.

Simplify supports an Initiate HEM/IngEstate message from the POS process. This message can be used to determine whether an updated package is available for downloading. Packages are used to download an updated Simplify application, parameter files, form files, etc.

This message can also be used to update the TMS Identifier, by sending it in field 5001 of the request (optional). See sample Request below for details.

The Initiate HEM/IngEstate Response message includes the PIN Pad serial number as well as a Status flag indicating whether the PIN Pad was able to successfully communicate with HEM/IngEstate.

important

The Initiate HEM/IngEstate Message should only be sent when necessary and based on coordination with Elavon.

  • 008=Length of Data
  • 99990000=new TMSID

Response

An example of a possible Initiate HEM/IngEstate Response message (from Simplify to the POS process) is:

API Field #, ValueDescription

HEM/IngEstate Update Flow Chart

The HEM/IngEstate update process commanded from the POS operates as follows:

HEM/Ingestate update process flow. See text just below.

POS sends Initiate HEM/Ingestate (36-07) request to Simplify.

Simplify attempts to communicate with the HEM/Ingestate server.

  • If not successful, Simplify sends Status Flag to POS in an Initiate HEM/Ingestate response:
    • 01 = PIN pad busy.
    • 02 = Comm error. PIN Pad may reboot.
  • If successful, Simplify sends Status Flag = 00 in response. PIN pad displays ‘Connection’ and checks whether updated Simplify file are available.
    • If no, Simplify reboots.
    • If yes, Simplify download the available files from HEM/Ingestate, applies the updates, and reboots.
