The Siemens 6GT2803-1AC00 is a SIMATIC RF310M handheld terminal — basically a rugged mobile RFID reader with a built-in touchscreen and Windows Embedded CE 5.0. It's designed for field use reading and writing RF300-series and ISO 15693 (RF200, MOBY D) transponders at 13.56 MHz. The integrated battery gives you about 8 hours of typical run time between charges. IP54 rating means it handles dust and splashing water — fine for a warehouse floor or a production line walk-around, but don't hose it down. Rated for a 1.5 m drop onto concrete, so it survives the occasional fumble.
Key specs that matter for fit
The 3.6-inch VGA color touch display (480 × 640 pixels) is readable indoors; don't expect sunlight readability on a bright loading dock. Alphanumeric keypad means you can type serial numbers or location codes directly on the unit. Communication is through the tether port (RS232 and USB 1.1) or the docking connection with low insertion force (LIF) contacts. The docking station and WLAN module are listed as accessories — not included, so factor those into your BOM if you need wireless or a charging cradle. Data memory is 900 Mibyte usable from a 1000 Mibyte total program/data memory — enough for tag databases and application code. The RAM sits at 256 Mibyte. The operating system is pre-installed Windows Embedded CE 5.0 with RF310M.exe for transponder execution. The lithium-ion battery is permanently installed and not customer-replaceable — that's a service-center swap when it wears out. Fast charging is supported through the docking station.
Operating conditions and handling
Operates from -20 °C to +50 °C, stores from -40 °C to +60 °C. The storage range is wider because the battery is disconnected in storage — don't run the unit at -40 °C. The 3 A·h battery capacity supports the 8-hour typical runtime; actual runtime depends on read/write duty cycle and display brightness. Multitag reading is not supported — this unit reads one transponder at a time. The maximum transfer rate over the air is 106 kbit/s, which is typical for 13.56 MHz HF RFID. Protocols supported are RF300-specific, ISO 15693, and ISO 18000-3.
