In order to calibrate the reader for 32.5 dBm, use the following table to look-up a
corresponding index number to write to the reader. As shown in the following table,
32.5 dBm corresponds to an index of 0e.
To write the index of “0e” to the reader, perform the following:
1. To set the reader for 32.5 dBm at the port 1 antenna connector, execute the
following the following CHUMP command:
}cw,d:TP0,b:0e000000,f:1!
where:
The digit following TP is the port number minus 1.
The left two digits of the eight bit word are the index number (0e).
2. Connect a power meter connected directly to port 1. The meter should read 32.5
dBm. The power meter should read 30 dBm if connected to the end of the 15
foot cable.
3. Repeat this procedure for each port.
