These options only apply to UHF, UHF8 and Hybrid systems, users of DF (dual frequency) systems can ignore these options.
UHF enabled (p54)
This setting tells the reader what kind of UHF reader it is.
Format: F or 4 or 8 or Hybrid 4 or Hybrid 8. Must be set to 4 for UHF4 systems, 8 for UHF8 systems, Hybrid 4 for UHF Hybrid 4 systems, and Hybrid 8 for UHF Hybrid 8 systems.
Default: F (for DF/Active systems)
Can be set in config.ini only.
Example: UHF enabled=F // DF system
orUHF enabled=4 // UHF4
orUHF enabled=8 // UHF8
orUHF enabled=Hybrid 4
orUHF enabled=Hybrid 8
UHF active antennas (p56)
This controls which antenna ports should be active.
It is important to make sure that if a port is designated as active, an antenna should be plugged into it otherwise damage to the reader might occur.
If this is set to auto then pressing the “setup” button on the reader will scan and detect the antennas connected.
Format: auto for autodetect – this is recommended*. Otherwise a list of antennas separated by commas like 1,3,4
Default: auto
Can be set at any time.
Example: UHF active antennas=auto
UHF append long ID (p57)
A true/false setting which controls the format of all tag messages (raw and filtered).
When set to true, two decimal digits are appended to the end of the record (which give the length of the full ID) and then the full length UHF ID is appended.
Normally the records only contain 48 bits of tag ID, and some UHF tags require longer IDs to be used.
Format: T for true, F for false
Default: F
Can be set at any time.
Example: UHF append long ID=T
UHF drop ID bytes (p58)
This setting can be used to drop a number of bytes from the end of a UHF tag.
Format: A number from 0 to 255
Default: 0
Can be set at any time.
Example: UHF drop ID bytes=2 // Tag 0123456789ABCDEF becomes 0123456789AB
UHF region
Set the region of the UHF reader to comply with local radio compliance laws.
Format: China or Europe or USA or Korea or Japan or Australia or New Zealand
Note: your trident reader will be optimised in hardware to work on ETSI (Europe frequencies 865.6<->867.6MHz) or FCC (USA frequencies 902<->928MHz).
If you have an ETSI reader, then you must set the region to Europe, or else it will not function correctly.
If you have an FCC style reader, then the region must be set to one of the countries other than Europe.
Default: Leaves setting unchanged. It is highly recommended you set your region correctly.
Can be set at any time.
Example: UHF region=USA
UHF power low
UHF power setting, used when the power switch is set to “LO”.
Format: Number from 1 to 33dBm
Default: 27
Can be set at any time.
Example: UHF power low=27
UHF power med
UHF power setting, used when the power switch is set to “MED”.
Format: Number from 1 to 33dBm
Default: 30
Can be set at any time.
Example: UHF power med=30
UHF power high
UHF power setting, used when the power switch is set to “HI”.
Format: Number from 1 to 33dBm
Default: 33
Can be set at any time.
Example: UHF power high=33
UHF display decimal ID
When true, UHF tags will be decoded as a decimal number, rather than being displayed in hex.
Please note that only the last 64 bits will be converted to a decimal number. This means the largest number which can be encoded is 18446744073709551615.
Format: T for true, F for false
Default: F
Can be set at any time
Example: UHF display decimal ID=T
UHF EPC Filter
This parameter can be used to accept only certain UHF tag scans and reject others.
Format: zero to eight hex nibbles. The beginning of the received tag must match the filter. Eg filter of E2A will only match tags starting with E2A...
Default: blank
Can be set at any time
Example: UHF EPC Filter=E2A // accept only tags beginning with digits E2A
