Step 2:
Scan the cable connected to the RF Out port on the AMS with a spectrum analyzer. Look for any
traffic or noise between 900 to 935 MHz. If these is no noise or traffic on 910 MHz, keep “Frequency” at 910
under “Common Info”. If there are issues on 910 MHz, adjust “Frequency” in 1 MHz intervals higher to a
frequency clear of noise and traffic. Click “Set” to save number.
Step 3:
Ensure “Power” under “Common info” is set to 35. Click “Set” to save number

Step 4:
Click on the [Tag Scan] tab and then “Read” to gather tag information. Click “Export” to save the list
of tag IDs.
Step 5:
Adjust “Polling” for desired dry contact alarming cycles. Click “Set” to save settings.
Period(sec) – The time between each scan.
o
Must be minimally 120 sec.
Alarm CycleNum – The number of consecutive scans that must occur to the same tag ID error
before an alarm is triggered on the dry contacts.
o
EX: If period is 120 sec and Alarm CycleNum is 1, the AMS must have 2 scans
back-to-
back
with the same tag ID in alarm, to trigger the dry contact alarm. This would mean that
the alarm won’t appear until 6 minutes have passed (120 sec before each scan + 60
seconds to complete the RFID Tag scan. The first scan being the reference scan and
second scan being the
1
back-to-back comparison). This will trigger if any of the tags are
consecutively missing after the scan. It does not have to be the same consecutive tag. If any
scan finds a missing tag in the next scan, this will break the consecutive count needed for
that tag to trigger an alarm. It does not affect other tags in their own consecutive count.
