Description

About the RF240R reader ASCII SIMATIC RF200 Reader RF240R; RS-232 interface (ASCII/scan mode); IP67, -25 to +70 °C; 50x 50x 30 mm; with integrated antenna.

The Siemens 6GT2821-4AC40 is a SIMATIC RF200 RF240R ASCII RFID reader with an RS232 interface running in ASCII/scan mode, so it connects directly to a PC or control system without a SIMATIC communication module. Built into a 50 x 50 x 30 mm housing with an integrated antenna, it reads ISO 15693 transponders at 13.56 MHz and carries an IP67 rating for -20 to +70°C operation.

Selection Notes

The RS232 ASCII/scan-mode interface is the key difference from the RS422 version of this reader: it lets the reader output tag data as plain text straight to a PC or scanner input, skipping the SIMATIC communication module the RS422 variant needs. The 30 m maximum wire length is far shorter than the RS422 version's 1000 m, so this reader belongs close to the connected PC, not at the far end of a machine. Choose the RS422 variant instead when the reader has to sit on a long cable run back to a SIMATIC communication module; choose this ASCII variant when a PC or third-party scanner input is the endpoint.

Applications

Used where tag data needs to reach a nearby PC or terminal directly, such as manual read stations, packing benches, or scan-mode kiosks, without routing through a SIMATIC communication module.
