Bench Test Procedure
The ALR 9890 – RR is a source of RF energy. When connected to a
system including an antenna the radiated RF emissions must be
evaluated in accordance with FCC OET Bulletin 56 “Hazards of radio
frequency and electromagnetic fields” and Bulletin 65 “Human
exposure to radio frequency electromagnetic fields” and appropriate
precautions implemented. Avoid close, prolonged exposure to the RF
emissions through good laboratory practice including:
 Turn off transmission when not making measurements
 Aim antenna away from personnel when in use.
 Maximize distance between the antenna and people.
1. Access an operational mode suitable for bench testing.
 The reader defaults to the AAR – S-918 protocol on boot up.
 Reading of Class 1 Generation 2 tags may be enabled under command
in the Gateway application.
 Refer to the applicable software application user guide for specific
instructions.
2. Position the reader so you can see the diagnostic LEDs.
 You may also want to position the PC so you can view the monitor
simultaneously for later tests.
3. Move a tag slowly away from the antenna’s range.
 Begin with the tag well inside the expected read range (~2m or 6 ft) and
move it toward the antenna while observing the LEDs.
4. Verify the SNIFF LED illuminates when the tag approaches the read
window.
 SNIFF should be illuminated green.
5. Verify the READ LED illuminates when the tag is inside the read
window.
 READ should be illuminated green.
6. Verify the host receives the tag data.
 Refer to indications specified in applicable user guide to verify the tag
was read successfully.
7. If bench test conditions are verified, proceed to installation.
NOTE: To perform a hard reboot of the system, simply cycle power on the reader.
