| device_type | DIN-rail RS485-to-LTE Cat.4 industrial cellular modem (DTU) with global bands; PUSR's product narrative states Modbus RTU-to-Modbus TCP conversion |
| modbus_register_map_available | False |
| modbus_register_map_note | PUSR publishes no Modbus register map for this device: it is a protocol converter / gateway, not a Modbus slave with an addressable register file. |
| modbus_rtu_to_modbus_tcp_gateway |
claimed true - but see caveat
USR-DR504-G — official product page — 'Modbus RTU to Modbus TCP'. CAVEAT: the claim appears only in the page narrative; the specification table's Protocol row lists TCP/UDP/DNS/HTTP/FTP and no Modbus, and the same sentence is reused on USR-G781. Flagged in review.
