15) If using an MPR with multiple external antenna ports, attach an antenna to a port. The MMCX
connector is a press-fit connector; push gently inwards until you feel it ‘click’ into place. Pull outwards to
remove the connector. Note that the connector is mechanically delicate, and should be protected from
excessive stress. If a long antenna cable is used, the portion of the cable near the card should be supported
to ensure that it does not pull laterally on the connector.
16) select Ant A or Ant B radio buttons to select the antenna port used by the card (MPR6000/7000 only).
The naming convention for the ports is shown below. Note that the MPR6000/7000 devices automatically
detect excessive reflected power at an antenna port and attenuate the output signal to protect the amplifier;
therefore no harm is done to the unit if you direct it to the wrong port, or forget to attach the antenna
connector.
17) Click the "Get Inventory" button. Tags should appear in the box as they are read. Each new tag icon
is accompanied by an alert sound. The type of icon indicates whether a class 0/0+ or class 1 tag was read;
below each icon the full ID of the tag is displayed as a hexadecimal number.
18) The software can be set to inventory only class 0 tags, only class 1 tags, or to alternately search for
both types, using the Inventory Type pull down menu:
19) The time that a tag icon remains displayed on the screen once it has been read can be adjusted with the
Persist Time pull down menu. If ‘Infinite’ is selected tag icons will accumulate on screen until the
inventory process is terminated or the screen is full.
