1 INTRODUCTION Product Description © The Hadron (Model R4320C), embedded module of the easy2read product line, is a RAIN RFID multiregional compact reader for high performances applications. With programmable output power from 10dBm to 31.5dBm, the reader reaches top reading performances being able to detect RAIN tags from a distance of 9 m (30 feet) depending on the antenna and the tag used.
The Mod. R4320CEVB - R4320C Hadron Evaluation Board allows managing the Hadron R4320C reader directly via USB and RS232 interfaces. This board is particularly suited for Hadron R4320C reader evaluation and SW development purpose. Fig. 1.

External Connections The location of the connectors is shown in Fig. 2.1: Hadron R4320C Technical Drawings page 11. Their part numbers are listed here below: Antenna Ports: RF Coax Connector Huber+Suhner type 82_MMCX-S50-0-2/111_K (to be used with Huber+Suhner type 11_MMCX-50-1-1/111_O) MOLEX Connector: PCB Header Molex type 53261-1571 (to be used with Molex Type 51021-1500 + 15pcs crimp terminal type 50058-8100) Fig. 2.
The RXD/TXD pins are used to communicate with the R4320C board via UART port; to establish a link with the device 2 you must configure your COM port as follows : Baud rate: 115200 Parity: None Data bits: 8 Stop bits: 1 Flow Control: none 5V USB signal is used to sense the presence of an USB host device connected to the module and not for supply the device. This pin shall be left unconnected for UART operation.
Power supply connection In the following schematic suggested R4320C power supply connection is shown. The use of a resettable fuse (F1) is recommended since R4320C does not provide internal current limitation protection. Diode D1 avoid damage to the reader in case of reverse polarity connection. Fig. 2.2: Hadron R4320C Power Supply Connection General purpose I/O connections The GPIO0-GPIO3 pins are 4 general-purpose bidirectional pins.
Shutdown pin R4320C SHUTDOWN pin allows to set the module in power off mode (current consumption less than 1mA) and can be used also for manual reset operation. SHUTDOWN pin is pulled-down by an internal resistor. Fig. 2.4: Hadron R4320C SHUTDOWN pin connection Communication interface selection The communication with Hadron R4320C module can be performed via UART or USB interface.
Fig. 2.5: Hadron R4320C RS232 Connection FW Recovery/Upgrade ERASE pin is reserved and shall be used only to perform the microcontroller FW recovery/upgrade procedure during which it must be forced at high level (3.3V or 5V). In the following diagram a manual recovery mechanism is shown: in order to perform the R4320C boot recovery the jumper JP shall be inserted, then R4320C module shall be switched on for 5s at least.
Antenna port specifications In the following table the pinout of R4320C antenna ports is shown.

2) Power on the board for at least 5s. 3) Remove the power supply. 4) Place the jumper in the original position. 5) Connect the USB or the RS232 cable to the board. 6) Power on the board. 7) Launch the R4320C Upgrade Tool and click on Next button. 8) Select the COM port related to the device (the COM address of RS232 in case of use of the serial interface, the Bossa Program Port assigned by OS in case of use of the USB interface).
12) Switch off the module; at the next power on the device will be operating with the new FW image.
