The connector type is Molex 4320288113 or equivalent.
5.2.1.1 Program Connector The connector is a Hirose DF9-11P-1V(32). Signal Name Signal Type Pin Number MCLR Data J15-1 3V3_VDC Power J15-2 AGND Ground J15-3 PGEDI Data J15-4 PGECI Data J15-5 10k_pullup Data J15-6 SPI_MOSI Data J15-7 SPI_SCLK Data J15-8 SPI_MISO Data J15-9 PM_CS Data J15-10 NC NC J15-11 AGND Ground J15-12 AGND Ground J15-13 5.2.1.2 RF Connector The MMCX connector is a Molex 0734150961.
6. Hardware Description 6.1 Power 6.1.1 Input Power The RFID reader board derives all power from the 12VDC(+/-10%) and 5VDC(+10%/-5%) as defined per the MODBUS connector. The reader generates 3V3 from the 5VDC rail using an MCP1700T LDO rated at 250mA. The 5V2 voltage is generated from the 12VDC rail using an AZ1117LDO rated at 800mA. 6.1.2 RF Output Power When configured for 5-V operation (see section 6.6), the RF amplifier voltage can be set from 4.3V to 5V in 100mV steps via software.
6.4.3 Debug/Personality Module Support The reader board can be programmed and/or debugged from a Microchip ICD 3 module via J15. The connector is also compatible with Manitowoc’s personality module for applications that desire external flash memory. 6.4.4 Reset The reader board can reset by momentarily grounding (~100ms) J15-1 pin. This will cause the entire board to reset and restart the initialization routine. 6.5 Communication Peripherals 6.5.
6.7 RF Analog Multiplexor The reader board switches the main RF channel to any one of the 12 available RF ports using Peregrine 4 SP4T PE42440 RF switches. This part feature ESD protection as well low series resistance and insertion loss at the 13.56MHz carrier frequency. The RF switches are the reflective type as absorptive are not required for this application.
To start the bootloader application the master device command the RFID reader board to switch to bootloader program using modbus interface (P-BUS). When the firmware update is done, the master device commands the RFID reader board to start execution of the main application. Each frame has address, function code, packet data and CRC16.
When a read is completed successfully, SystemController update the modbus registers with the read value. If no tag is detected then the channel data is set to 0's. 7.5 Communication Bus Drivers 7.5.1 MODBUS Interface The UART4 module is configured to be used for modbus communication on the P-BUS. The UART4 is configured to run at 115200 baud rate, no parity and one stop bit. The driver is developed to be interrupt driven and non-blocking functions to be suitable for use with the QP frame work.
