2.3.1 Bench Test Configuration for Serial Communication
1) Situate the Reader on a tabletop
Ensure the following conditions:
•
Two standard 220 VAC outlets are available nearby (one for the reader,
one for the PC if needed).
Sufficient space is available on the tabletop for the PC, reader and antenna.
2) Connect the RS-232 cable to the reader.
•
Align the male cable connector so that its shape and pins match the shape
and holes of the female DB-9 RS-232 port.
•
Push the aligned connector into the port.
•
Finger-tighten the screws to secure the cable/connector to the reader.
3) Connect the RS-232 cable to the serial port on the PC
4) Connect the power supply to the reader
Using the thin cable attached to power supply, push the connector into the
port until it is securely seated. Do not plug the power supply into the wall
outlet yet.
5) Connect the coaxial cable(s) to antenna port(s) (1-2)
•
Antenna port 1 is on the right if viewing reader with flange side down. The
RFS-2312 has two antenna ports.
• Align the coax cable’s center pin and push into the port.
•
Screw the fitting from the cable end onto the reader connector
clockwise
until finger-tight to secure the cable to the reader.
•
Connect additional antennas to their respective ports and tighten fittings
clockwise until finger-tight.
