DCRs over Ethernet(OEMV) or Serial

Identify and fix DCR errors based on whether DCRs are over OEMV(Ethernet) or Serial(using FCI).

If DCRs remain unresponsive after Poll Error Troubleshooting, use the flow below based on channel type.

If you still need to confirm OEMV vs Serial, follow the connection type checks in Poll Error Troubleshooting Guide.

If DCRs are over Ethernet (OEMV)

1

Check Online/Offline state in Forecourt Diagnostics

Use Forecourt Diagnostics to confirm whether DCRs are Online or Offline/Not located.

Forecourt status (OEMV / Ethernet)

Use this to confirm whether each DCR is communicating with the Site Controller (Commander).

In Config Client, go to:

Tools → Helpdesk Diagnostics → Forecourt

For each DCR, confirm:

  • Located → shows the DCR number.

  • Status → shows Online (communicating).

If the DCR is missing, not located, or shows Offline, the DCR is not communicating.

Forecourt Status
2

Confirm the DCR channel is IP Enabled

  • In Configuration Client: Select Tools → Managed Modules →

Host Names: sitecontroller→ Select Module: DCR Driver → DCR Channel 01

  • Navigate to Advanced Settings and verify that IP Enabled is selected.

3

Confirm OEMV was previously working

Ensure that the DCRs operated correctly after enabling Ethernet/OEMV.

For a new OEMV transition, ensure OEMV settings are verified first.

4

Before Initializing EMV/EMV Init

Before performing Initialize EMV/EMV Init, confirm:

  • All pumps/fueling positions are Idle

  • No Active transactions or customers at the pumps.

This prevents Initialization errors and stuck fuel sales.

5

Initialize EMV or Init EMV (only if DCR POP IDs exist)

EMV Initialization Process

  1. Check that all DCR POP IDs are included in the Available POP List by doing the following:

  2. If your site is Tesoro/ARCO, see Note below prior to Initializing EMV

  3. Login to Config Client, Go to:

Payment Controller > EPS Configuration > EPS Global Configuration >

EMV Initialization

In the DCR POP list:

  • IDs starting with 0 are Indoor Pinpads.

  • IDs starting with 1 are DCRs(Dispenser Card Readers).

  1. Select the affected DCRs from the Available POP list(e.g., enter 101 for DCR#1, 102 for DCR#2, etc.) and press Add to add it under Selected POP List and Save

  2. When Save is pressed, there will be a prompt to enter the OTP

  3. To obtain the OTP, go to : CSR Function > Maintenance Menu > Generate Config OTP

  4. Enter the OTP and the EMV Initialization will start.

Follow these steps to ensure proper configuration and operation of the DCR units.

6

Push DCR data in order

Run the pushes in this order:

Before Initialize DCR Driver, confirm:

  • All pumps/fueling positions are Idle

  • No Active transactions or customers at the pumps.

This prevents Initialization errors and stuck fuel sales.

1. Initialize DCR Driver

Before Downloading to All DCRs or Initializing All DCRs, confirm:

  • All pumps/fueling positions are Idle and

  • No Active transactions or customers at the pumps.

This prevents Initialization errors and stuck fuel sales.

2. Download to DCRs

After any configuration change, run Refresh Configuration, Download to DCRs and Run Initialize Fuel only if needed. This pushes the updates to all fueling positions.

1. Refresh Configuration:

  • Navigate to Tools , then select Refresh Configuration.

Before Downloading to All DCRs or Initializing All DCRs, confirm:

  • All pumps/fueling positions are Idle and

  • No Active transactions or customers at the pumps.

This prevents Initialization errors and stuck fuel sales.

2. Initialize DCRs (All):

  • In Config Client: Forecourt → Initialization → DCR

  • Enter 0 (All) or select All.

Before Initializing Fuel, confirm:

  • All pumps/fueling positions are Idle and

  • No Active transactions or customers at the pumps.

This prevents Initialization errors and stuck fuel sales.

3.Initialize Fuel (if necessary):

  • In Config Client: Forecourt → Initialization → Fuel

If all DCRs are affected, there could be a network issue at your site. Check the on-site firewall/MNSP path. Contact your site’s MNSP provider(Ex: Cybera, Hughes, Mako, Sagenet, etc.) to confirm the DCR network path is up and online.

Note:

Tesoro / Arco : Before Initializing EMV

  1. Contact the Payment host to verify the site is configured for OEMV outside on their end.

  2. Confirm with Payment host, the Trigger pull & EMV tables are flagged for download.

  3. Run Trigger Pull, then EMV PDL.

  4. Only then Initialize EMV to the DCR POPs.

If DCRs are over Serial (Legacy) — Base 53.27 and below

1

Verify power to the FCI

Remove the thumb screws on the FCI box (FCI) and check for lit LEDs inside.

FCI images (LED examples): use these as a visual reference for what “powered” looks like.

FCI Image power LED
FCI image — LEDs example 1
FCI Box image
FCI image — LEDs example 2
FCI Box Image
FCI image — LEDs example 3
2

Reseat power if needed

If no LEDs, reseat power and try a known-good outlet.

3

Before Downloading to All DCRs or Initializing All DCRs, confirm:

  • All pumps/fueling positions are Idle and

  • No Active transactions or customers at the pumps.

This prevents Initialization errors and stuck fuel sales.

4

Run Download to DCRs

Login to Config Client:

Select Forecourt → Initialization → DCR(All)

If DCRs still show No change after Initialization attempts, Contact the Verifone Helpdesk.
