Compatibility Cross-Reference & Model Map
RHID Railway RFID — AAR S-918 / ISO 10374
RHID railway RFID products (RHD916A reader and RHD-916TAG tag) are compliant with the open standards AAR S-918 and ISO 10374. Because these are published interoperability standards, RHID equipment works with other standard-compliant tags and readers. The tables below give a model-level cross-reference for procurement, replacement, and system-integration planning.
Scope. This page covers interoperability under AAR S-918 / ISO 10374 (915 MHz UHF backscatter, FM0 / AAR encoding) only. Other UHF RFID standards — for example EPC Class 1 Gen 2 / ISO 18000-63 (used by Siemens SIMATIC RF650R/RF680R, Impinj, Zebra) — are different air interfaces and are not covered here; RHD916A / RHD-916TAG do not interoperate with Gen2 equipment.
Verified interoperability (confirmed by RHID)
The RHD916A reads TransCore AT5110 / AT5118 / AT5133 tags, and TransCore AEI readers read the RHD-916TAG — they share the same AAR S-918 air interface (915 MHz UHF backscatter, FM0 / AAR encoding). Operation is bidirectional; no reader change is required when replacing foreign tags.
1. Tag Cross-Reference
| Brand | Representative Model(s) | Standard | RHID Equivalent | Interop. | Notes |
|---|---|---|---|---|---|
| TransCore | AT5110 / AT5118 / AT5133 | AAR S-918 | RHD-916TAG | Yes — bidirectional | Same air interface; confirmed by RHID. AT5118 = standard-temp tag, AT5133 = high-temp tag. |
| Amtech (TransCore) | AAR S-918 tags | AAR S-918 | RHD-916TAG | Yes | Amtech's technology is the basis of AAR S-918 and Amtech was acquired by TransCore. Legacy Amtech tags interoperate by standard. |
2. Reader Cross-Reference
| Brand | Representative Model(s) | Standard | RHID Equivalent | Interop. | Notes |
|---|---|---|---|---|---|
| TransCore | Encompass 4 (P/N 10-4004-008), SmartPass 4, Encompass 1 Rugged (E1R), E1150 Mobile Reader | AAR S-918 | RHD916A | Yes — bidirectional | RHD916A reads TransCore tags and TransCore readers read RHD-916TAG. Same air interface; confirmed by RHID. |
| Amtech (TransCore) | AAR S-918 readers | AAR S-918 | RHD916A | Yes | Legacy AAR S-918 readers interoperate by standard. |

Accuracy note. Interoperability depends on matching air interface and data format. Where a specific model's air interface is uncertain, verify against actual units before deployment.
