Product information

Description

Promag PCR-300 is a compact 125 kHz RFID reader designed to read EM4102 proximity tags and provide data output via RS232 emulation. The reader is intended for straightforward integration with legacy controllers, access control panels and serial-based systems where a simple serial data stream representing tag IDs is required. Its small footprint and standard interface simplify installation in access points, turnstiles, and attendance terminals.

Advantages

The Promag PCR-300 supports the widespread EM4102 tag format operating at 125 kHz, ensuring compatibility with many passive proximity cards and fobs. RS232 emulation facilitates connection to older controllers and devices that accept serial input without specialized drivers. The compact housing and fixed read range offer reliable tag detection in close-range identification tasks while keeping installation and wiring straightforward.

Suitable for

  • Access control readers for doors and gates
  • Time and attendance terminals
  • Identification of personnel and assets with 125 kHz tags
  • Integration with legacy systems requiring serial input

Key specifications

  • Operating frequency: 125 kHz
  • Supported tag format: EM4102 (125 kHz proximity)
  • Interface: RS232 emulation (serial data output)
  • Form factor: compact reader housing for flush or surface mounting
  • Power supply: low-voltage DC operation (refer to manufacturer documentation for exact values)
  • Typical use range: short-range proximity reading suitable for access and identification

How to use

Install the Promag PCR-300 at the desired entry point following standard mounting practices and wiring for a serial-enabled controller. Connect power and the serial data lines according to the controller’s RS232 input configuration; the reader will emulate a serial device and output tag IDs when an EM4102 tag is presented. Configure the receiving system to parse the serial stream and map the tag identifiers to user records or access rules. Place tags within the reader’s effective range to ensure reliable reads.

Usage recommendations

For reliable operation, mount the reader away from large metal surfaces and high-frequency interference sources. Verify the controller’s RS232 settings (baud rate, parity, stop bits) to match the reader’s emulation parameters and test reads with known EM4102 tags before final commissioning. Use compatible 125 kHz proximity cards or key fobs to ensure correct identification.
