HEM and IngEstate are Ingenico terminal management systems. Elavon maintains an HEM/IngEstate server to update Simplify PIN pads. This section explains how PIN pads are maintained.

## Signed sensitive files

For purposes of security, sensitive Simplify files are signed. Unsigned sensitive files, or files signed with a different certificate, will not be accepted by the PIN pad. If this occurs, a signing error message will be displayed after the file is loaded to the PIN pad. The merchant will then need to contact Elavon.

## Initiating HEM/IngEstate

HEM and IngEstate are Ingenico PIN pad management systems. Simplify is currently transitioning from the use of IngEstate to HEM.

The HEM/IngEstate update process can be initiated manually on the PIN pad, by command from the POS (see the *Ingenico Simplify Developer Guide* under :magic-link[Initiate HEM/IngEstate Message]{id="initiate-hem-or-ingestate-message-tran-type-3607"} for details), or scheduled by Elavon. Once initiated, the process proceeds automatically. When the update process is complete, the PIN pad will reboot.

The HEM/IngEstate update process can be initiated manually from the **Elavon Sub Menu**. As described under :magic-link[Accessing the Elavon Main Menu]{id="accessing-the-elavon-main-menu"}, this menu can be accessed during the PIN pad boot up sequence. (See :magic-link[Navigation and data entry on Ingenico PIN pads]{id="navigation-and-data-entry"} for device-specific details.)


::image{id="/content/dam/developer-portal-solutions/en-us/elavon/media/images/products/simplify/image35.jpeg" alt="Elavon Sub Menu"}


Select **Initiate HEM/IngEstate** from the Elavon Sub Menu to initiate the HEM/IngEstate update process.

## Viewing Simplify load information (0 Screen)

Information on the Simplify load present in the PIN pad is displayed during boot up and by keying 0 when the PIN pad is in a closed state. (To lengthen the display, press the + or -- key.) For additional fields, scroll down. This information may be requested by Elavon for troubleshooting purposes. The PIN pad will return to the usual closed screen after several seconds.

|TMS ID: |TMS Identifier|
|Version: |Simplify load level information in two parts:<ul><li>Official PCI solution/version/build designation</li><li>User-friendly version/build information.</li></ul>Format is S–PP-X.YY.AAAAA-AAAAA, where:<ul><li>S = first part of prefix, indicates whether Simplify is operating as part of a PCI P2PE-validated solution. (V = validated or N = non-validated). **Note:** This value depends on additional software used in the solution (besides Simplify). Specifically, this value indicates whether the most recent transaction processed by Fusebox came back validated or not.</li><li>PP = second part of prefix, indicates encryption type. (OG = On-Guard or G2 = Voltage)</li><li>X.YY.AAAAA = Official Simplify version and build information **Note:** For purposes of documenting Simplify PCI P2PE compliance, PCI is not concerned with the version/build (AAAAA). The designation currently used to document that Simplify is operating as part of a validated solution is V-OG-2.03.AAAAA.</li><li>AAAAA – User-friendly version and build information:<ul><li>AA = Simplify “Version”</li><li>AAA = build</li></ul>E.g. 28121 = “Version 28” build 121.</li></ul>For more information, see the *Simplify Ingenico Developer Guide* under :magic-link[Versioning]{id="versioning"}.|

:::::notice{note }

** **IP Eth**: initially displays the partially masked IP Address of the PIN pad (as shown above). An optional feature is available allowing this field to display the unmasked address. If this feature is present, pressing Enter at the load information screen will display a login screen. After logging in on this screen (special password required), the load information screen will be redisplayed with the IP Address unmasked. Please contact your Elavon representative if you want to implement this feature. 
:::::


## Remote Key Injection

Simplify supports Remote Key Injection (RKI). This section documents how to determine the outcome of an attempted key injection. For more information on RKI, consult your Elavon representative.

When the PIN pad restarts after an attempted key injection, RKI messages will be displayed during the bootup sequence. The first RKI message will always be as follows:

::image{id="/content/dam/developer-portal-solutions/en-us/elavon/media/images/products/simplify/image60.png" alt="RKI Processing screen" max-width="" max-height=""}

This message will be followed by a second RKI message indicating the outcome of the attempted injection. There are three possible scenarios:
- If the RKI file downloaded to the PIN pad is invalid, the following error message will be displayed:
 
::image{id="/content/dam/developer-portal-solutions/en-us/elavon/media/images/products/simplify/image63.png" alt="Load Error 205 IPPK0 screen"}

- If the RKI file is valid, but the serial number in the file does not match that in the PIN pad, an error message will be displayed showing the L4 serial number of the PIN pad. E.g.: 
 
::image{id="/content/dam/developer-portal-solutions/en-us/elavon/media/images/products/simplify/image62.png" alt="No RKI Maintenance Found screen with device serial number"}

- If the key injection is successful, the following message will be displayed: 
 
::image{id="/content/dam/developer-portal-solutions/en-us/elavon/media/images/products/simplify/success.png" alt="Successful Load IPPK0 screen"}

 
## Exiting reversal mode

The host approval will need to be reversed when either of the following situations occur:
- An EMV transaction is approved by the host and declined by the chip.
- The customer removes their card from the chip reader before the transaction is completed.

If a reversal is needed, Simplify will go into reversal mode to force the reversal. It does this by sending a Reversal (Tran Type 11) to the host, and resending the reversal (if necessary), until a response is received. While this is taking place, any other transactions that are
sent to the PIN pad will be processed offline.

The PIN pad can be rebooted and commanded to exit reversal mode from the **Elavon Main Menu**, as follows:

1. Reboot the PIN pad. When a rectangle appears in the lower right corner of the screen, press the **Enter** (green) key to display the **ELAVON SUB MENU**.

2. Select **Elavon Main Menu** and login to display this menu.

3. Scroll down and select **REMOVE EMV REVERSAL** (only present if currently in reversal mode).

4. Select **RESTART** to reboot the PIN pad.

If Simplify is forced out of reversal mode, the data required to request the reversal is sent to the POS in a **Void Sale response** (11) message, after which the PIN pad returns to normal processing mode.

:::::notice{important } 
Forcing Simplify to exit reversal mode is an exception procedure that should only be used when necessary. If Simplify is forced out of reversal mode, the merchant will be responsible for ensuring that the transaction is reversed by the host, using the data in the **Void Transaction response**. Elavon strongly recommends allowing Simplify to reverse all host-approved transactions that are declined by the chip.
:::::

## TLS 1.2 cipher groups

The following TLS 1.2 cipher groups (suites) are supported for Simplify build 121:

- TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 (0xc030)
- TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384 (0xc02c)
- TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384 (0xc028)
- TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384 (0xc024)

- TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256 (0xc027)
- TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256 (0xc023)
- TLS_RSA_WITH_AES_128_GCM_SHA256 (0x009c)
- TLS_RSA_WITH_AES_128_CBC_SHA256 (0x003c)
- TLS_EMPTY_RENEGOTIATION_INFO_SCSV (0x00ff)
