1.4 Reader Installation
◈ How to install antenna correctly ◈
1. Avoid metal material the front side of antenna in 2M due to cause of low performance.
2. Make the antenna stay still.
3. Antenna Cable per each ports should be not tangled and tied up.
◈ How to install or connect reader with antenna ◈
◈ When connection Antenna cable
for each port, connect SMA Type
connecter to main body and N Type
connecter to Antenna.
◈ Connect RS-232 cable for serial communication
checking with right direction of the connecter.
◈ Connect adapter with power
supply code then connect adapter
jack to main body.
◈ In case of use of multi connect or
extension cable, avoid to exceed
voltage(rated current) over than
mentioned.
1. Make the reader stay still.
2. Connect each cable in the package.
◈ Connect LAN cable to main body
LAN port for Ethernet
communication.

3. FCC Information to User
This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential
area is likely to cause harmful interference in which case the user will be required to
correct the interference at his own expense.
This device complies with Part 15 of FCC Rules.
Operation is subject to the following two conditions:
(1) the device may not cause interference, and
(2) the device must accept any interference, including interference that may cause
undesired operation of this device.
4. WARNING TO USER
－ Change or modifications not expressly approved the manufacturer can void the
user's authority to operate this equipment.
－ This equipment must not be co-located or operated in conjunction with any other
antenna or transmitter.
