PRODUCT DESCRIPTION
6GT2821-4AC10 RF240R RS422 RFID Reader
Siemens 6GT2821-4AC10 is the SIMATIC RF200 RF240R reader with an RS422 interface and 3964R protocol. Its 13.56 MHz air interface supports ISO 15693 and ISO 18000-3 transponders, with a documented read/write distance up to 65 mm depending on the transponder. An eight-pin M12 connector carries the electrical interface.
The reader communicates at 115.2 kbit/s over RS422 and has a listed 26.5 kbit/s air-interface rate, with a 0.6 ms read/write time per byte. It takes a nominal 24 V DC supply within 20.4 to 28.8 V and draws a typical 0.05 A. The IP67 housing and three-color status indication support installation at the identification point.

SYSTEM INTEGRATION
Integrate 6GT2821-4AC10 within SIMATIC RF200
Connect the RF240R to a compatible interface using the specified RS422 wiring and 3964R protocol. Confirm that the host supports the reader data rate and command arrangement. The serial connection and the 13.56 MHz transponder interface have separate rates, which must not be interpreted as a single throughput figure.
Choose a supported ISO transponder and check the documented operating distance for that specific tag. Keep at least 120 mm between adjacent readers and observe the mounting instructions for metal surroundings. The stated 65 mm maximum is transponder-dependent and does not guarantee that distance for every installation.
Supply the reader within 20.4 to 28.8 V DC and use the correct eight-pin M12 mating connection. Preserve the sealing and cable installation needed for IP67 protection. Test reading and writing with the intended transponder at its actual approach and dwell conditions, using the status indication and host response to verify the link.
Features:
- Radio frequency: 13.56 MHz
- Air-interface standards: ISO 15693; ISO 18000-3
- SIMATIC RF200
Use 6GT2821-4AC10 only within the documented SIMATIC RF200 arrangement and applicable installation instructions.
INTERCHANGEABILITY
Replace 6GT2821-4AC10 within SIMATIC RF200
Record the complete RF240R code, host interface and transponder selection before replacement. Identify the M12 connector pin assignment and existing reader position. An RS422 3964R reader must be matched to that interface arrangement rather than substituted solely because another reader belongs to the RF200 family.
Isolate the supply before disconnecting the reader and protect the mating connector from dirt and moisture. Inspect the mounting surface, cable and sealing parts, and restore the documented spacing to adjacent readers. Retain the tag path and mounting orientation because those details affect the available identification distance.
After reconnection, check supply and serial status, then read and write the intended transponder through the host. Confirm the result at the actual operating distance and approach conditions. Where performance differs, examine tag type, spacing and nearby metal before attributing every unsuccessful transaction to the replacement reader.
