NovaStar Receiving Card Replacement Chart

Replacement reference

One chart for every NovaStar receiving card we stock: the like-for-like spare to order for each model, the lookalike models that are not direct swaps, and the cabinet checks and file backups to make before the order. Built from the same verified data as our interactive replacement finder.

Cards covered: 61 receiving cards
Documented “not direct” pairs: 118 pairings
Interactive version: Replacement finder
Stock: All cards, priced

How to read this chart

Each row is one NovaStar receiving card we stock. The chart answers three questions before you order a spare: which card is the like-for-like swap for the model on your cabinet label, which lookalike models are not safe to substitute, and what to verify on the cabinet before the order goes in.

Like-for-like — the same model is the documented spare. Match the full label, including suffixes such as -1/-2/-N.
Not a direct swap — models that look similar or share a family name but have a documented difference in connector, capacity condition or cabinet path. Open Before you order on the row for the reason.
Conditional — a cross-model change that is only valid after the cabinet maker has approved a tested conversion; the condition is spelled out in the row.

Prefer typing your model in? The interactive replacement finder gives the same verdicts one card at a time, with add-to-cart links. If a model is not listed here, send it through the quote form and we check it manually — we do not guess compatibility.

Why lookalikes are not direct swaps MRV210-1 — Same top side, but male vs female connector gender decides whether it can mate. MRV210-2 — Different header side and connector gender (male, bottom). MRV210-4 — Same female gender, but bottom-side headers — header side can still prevent installation. Save from the old wall first Working receiving-card configuration read and saved via NovaLCT before disconnecting the old board Full card label record and the working firmware information If the failed card left no saved file: get the original file from the cabinet maker or a known matching cabinet Photos of both sides of the installed card and the part it mates with

MRV210-2 — Same bottom side, but the connector gender differs (male). MRV210-3 — Same female gender, but top-side header location can block installation. Any other MRV210 suffix as substitute — Only after the cabinet maker confirms connector side, gender, hub pinout, module data mode, power and configuration-file path — family name alone is not enough. Save from the old wall first Working receiving-card configuration read in NovaLCT before unplugging the old card Full card label record and the working firmware information/version If no saved file exists: obtain the original file from the cabinet maker or a proven matching cabinet — do not guess from a similar screen Front and rear card photos plus mating hub-board photos (also needed for fit/quantity check)

Why lookalikes are not direct swaps MRV266 — Do not move an MRV216 configuration over until hub board, modules, card outline and manufacturer files are verified; similar service features do not make it a physical replacement. MRV416 — A similar capacity row does not prove compatible connectors, data path or cabinet configuration. Save from the old wall first Receiving-card program read back in NovaLCT before removal Cabinet configuration (scan, wiring, pixel map) — keep both files with the cabinet record Matching calibration data (needed to restore an even image after repair) Old-card and hub-board photos, cabinet model, driver IC, quantity for compatibility check (no verified public exact MRV216 firmware)

Any HUB75E receiving card — Comparable pixel count, but it "cannot simply take over a HUB320 cabinet" — hub board, ribbon layout, module data path differ. Save from the old wall first Receiving-card program (firmware) read back via NovaLCT before removing the old card Cabinet configuration (scan, wiring, pixel map) — keep both files, one does not replace the other Old-card photo, hub-board photo, cabinet model, module details and quantity for a compatibility request (no exact public MRV266 firmware verified)

Replacement chart FAQ

Short answers on reading the chart and ordering the right spare.

What does “like-for-like” mean in this chart?

It means the documented spare is the same model as the card already in the cabinet, matched on the full label including suffixes. A like-for-like swap keeps the hub board, ribbons and saved cabinet configuration unchanged, so the cabinet behaves exactly as before.

Why is a card in the same family listed as “not a direct swap”?

Family names group cards by generation, not by interchangeability. Two cards can share a prefix and still differ in connector gender or direction, hub interface, driver-IC capacity conditions or supported cabinet files. The row’s checks explain the specific documented difference for each pairing.

What should I save from the old wall before replacing a card?

Read back and save the receiving-card program and configuration in NovaLCT, keep the cabinet map with module and wiring notes, and export calibration data where the wall uses it. Each row lists the exact items for that model under Before you order.

My model is not in the chart. Can you still help?

Yes — send the model through the quote form with a photo of the card label. We check the documentation and answer with a verified option or an honest “no direct swap”; we do not guess compatibility from lookalike photos.

Are the spares in this chart in stock?

Each row links to the product page, which shows current price and stock. In-stock orders placed by 2 PM ET ship same day from our Florida warehouse.

Where does the data in this chart come from?

Every verdict is taken from the model’s official NovaStar documentation and our per-model product research, and each pairing was re-checked against the source before publishing. Pairings we could not document were removed rather than kept as guesses.
