A network configuration that determines if the static network address is being
used or if the DHCP server assigns the network address.
"0" DHCP is not active, use static network address
"1" DHCP is active; obtain network address from the DHCP server
When polling, the direction flag shows if a transponder enters or leaves the field.
The display that a transponder leaves the field can be activated via parameter
0x29. The data are interpreted in HEX format. That is, two ASCII characters in
the message equal one byte of data in HEX format.
Values:
"00" (0x00) The transponder leaves the field
"80" (0x80) The RSSI value changed  The transponder moved within the field
"FF" (0xFF) The transponder enters the field
With the UHFI20 software version (firmware 2.x), the EPC code has a flexible
length n from 0 to 31 data words (2 bytes data). An n byte is placed before the
actual EPC code and corresponds to the quantity of EPC data words. The EPC code
is transferred so that the LSB byte is transmitted first. The data are interpreted in
HEX format. That is, two ASCII characters in the message equal one byte of data
in HEX format. The following applies to the number of EPC data words:
0<=n<=31
Example:
ASCII string: "060C0B0A090807060504030201"
 Number of EPC data words: 0x06
 EPC: 0x0102030405060708090A0B0C
DHCP 1 byte
Direction 2 bytes
EPC (2n+1)*2 bytes
