GLOSSARY BT Bluetooth™ CW Continuous Wave dB Decibels DF Dual Frequency HMI Human Machine Interface PC Personal computer RFID Radio Frequency Identification RFU Radio Frequency Unit R/O Read-Only. This is the mode in which the reader gets the UID from the tag and happens in the presence of non-modulating readers. RS422 Differential transceiver interface for RS232 R/W Read / Write. This functionality can only happen in the presence of modulating readers.

3. Quick start (Reader connected to PC via USB – Full R/W capability) 1. Connect the reader to the host via the USB cable, and switch the reader ON. 2. Windows will detect a new device. Install the “CP210x USB Composite Device”. This driver can be downloaded from the manufacturer at Silicon Laboratories. Windows will detect readers above serial number 5020016 as IPICO Proximity readers. 3. Data format: Refer to IPICO’s serial protocol document. 4.
3. Data format The 26 bits of transmission from the reader to the panel consists of two parity bits and 24 code bits. The bits are transmitted in the order described. The first bit transmitted is the first parity bit, P1, it is even parity calculated over the first 12 code bits.
6. Operations overview The reader transmits CW carriers, which causes the tags in the RF beam to power up and start backscattering their ID codes back to the reader. The RF unit receives the modulated backscatter and decodes the tag ID’s. A time stamp is typically added by the reader for each tag read event (Wiegand mode is 26-Bit ID only). The data from the reader is transmitted immediately communication port to the host. No buffering takes place on the reader.
8. Troubleshooting Visual indicator guide · GREEN Random flashing indicates valid tag ID’s are decoded. · GREEN 1HZ flashing indicates Heartbeat (Shows Decoder is running). · RED Steady indicates Power ON. NOTE : in Wiegand mode the Greed LED will be under Host control Symptom Possible causes Reader switched OFF Red LED Off Power source faulty Reader faulty Transmitter not switched ON. Faulty Tag or incorrect Tag baud rate selection. Cannot read a tag although Host Tag not orientated correctly.
10. Technical specification Power supply USB type = 5V from PC @ 300mA requirement RS422 and Wiegand type = 9VDC @ 300mA (less than 5mV ripple) -10dBuA/m with 50% duty cycle (10ms ON/OFF) Transmitter power (Antenna power will always be set to be less or equal to the max allowed according to ETSI or FCC, typically 64.8dBuA/m at 10m) Operating frequency Antenna type CH1 TX = 125 KHz CH1 RX = 6.

Reader is to automatically Write (N, N=1-14) Memory page(s) of X5 tag F1 Main Application SW sends INITIALIZATION parameters down to the reader N=1 F1.1 Get USER DATA..and preload the reader with DATA for Page (N) One page at a time F1.2 READER is now ready and waiting for a tag to come in to the beam. As soon as a tag enters the beam the READER shall first determine if it is a RO or a RW tag by applying the "Mask" to the start of the ID see init() i.
