1.4.2 External Antenna Connector (J10)
The user has the option to work with an external RFID antenna connected to the USB-B1 device. Connector J10 is
where this should be connected. Eccel Technology Ltd provides a variety of RFID antennas which the user can use
together with this device.
1.4.3 External / PCB Antenna Selection Connectors J8 and J9
To switch between the PCB antenna and an external antenna, two jumpers have to be used with the J8 and J9
connectors. These jumpers (J8 and J9) are not mounted by default.
Before connecting an external antenna the user should remove the R13 and R14 resistors. These resistors are
mounted by default and connect the RFID chip to the internal PCB antenna.
We recommend using our external antennas from series RFID-ANT1356-50X50-xxx, where xxx is the cable in mm. They
have a read range of about 70mm, 50x50mm in size and 300 or 800mm cable length. We can also design antennas
with higher read range and custom dimensions on request.
