Chapter 3 — Developing and Using RFID Applications

IF2 Network Reader User’s Manual 43

EPCC1G2 Advance Medium Access Mode

Selects low-level protocol (such as tari and back-link frequency)

settings. If you are using CAEN tags, you must enable this mode

before the tags can be read.

This setting is equivalent to the EPCC1G2PARAMETERS or

EPCC1G2PARMS BRI attribute.

Dense Reader Mode

Allows the reader to hop between channels within a certain frequency

spectrum to prevent other readers in the area from interfering with

one another.

This setting is equivalent to the DENSEREADERMODE or DRM BRI

attribute.

Antenna Field Strength 1 to 4

Sets the RF power level (in dBm) for each of the 4 antenna ports. Valid

range is 15 to 30. Default is 30. Note that the maximum power level is

dependent on the region that the IF2 is operating in.

Use this setting to attenuate the antenna field strength. In some

situations, full output power can cause unnecessary interference. For

example, if the tag is close to the antenna, full output power might

overload the tag and cause unreliable behavior.

This setting is equivalent to the FIELDSTRENGTH BRI attribute.

Antenna Sequence: First through Eighth

Sets the RFID antenna to be used for each of up to eight tag inventory

operations. Choose any one of the 16 available antennas from the

drop-down list. If more than one antenna is enabled, the antennas fire

in this sequence.

This setting is equivalent to the ANTS BRI attribute.

Configuring the BRI Server

The IF2 BRI server handles communication between your application

and the RFID module. When your application is communicating with

the BRI server, the blue Intermec Ready-To-Work Indicator on the IF2

front panel turns on and stays on. For more information, see “About

the Intermec Ready-to-Work Indicator” on page 4.
