Fiserv Nashville North

Nashville North uses the Nashville front-end settling to the North (PTS) back-end — i.e. terminal capture. Board it like any Fiserv terminal (see the Fiserv Overview for the shared shape, SRS, and UMF coverage) using the Nashville North processor config, and supply the North settlement MID.

Boarding spec

Field	Value / format	Notes
Group ID	`10001`	Nashville front-end — same Group ID as Nashville Classic. The difference is the back-end/capture, not the Group ID.
Merchant ID (MID)	7 digits (`MerchID`)	Nashville front-end MID. Top-level `mid`.
Terminal ID (TID)	7 digits (`TermID`)	Top-level `tid`.
Settlement MID	12 digits	The North Settlement MID. VAR-sheet `settlement_mid` — optional on the request; defaults to a copy of `mid` if omitted.
MCC	4-digit	Top-level `mcc`.
Equipment (POS Solution)	`CreditCallLTDGTWRC` or `CRDCallResellerRCSS`	North terminal-capture solutions. VAR-sheet `equipment`.

Capture & settlement

Terminal capture (North PTS). The gateway holds transactions and submits the batch at cutoff. Boarding must match the host's configured capture mode — if you board terminal capture but the host has the MID as host capture (or vice-versa), settlement breaks.

Gotchas

Same Group ID as Nashville Classic (10001). Nashville North is not a different Group ID — it's the Nashville front-end paired with the North back-end. The flavor is chosen by the processor config, not the Group ID.
settlement_mid is the 12-digit North Settlement MID. Omit it and Koard copies mid; supply it explicitly when the North settlement MID differs.
Capture-mode mismatch = broken settlement. Confirm the host has the MID set to terminal capture before going live.
tid is zero-padded to 8 as the Datawire AuthKey2.
