PARAMETER ISSUES AND DEFINITIONS

4.3.2 Address Stamping
If enabled, this command includes the RF device or DLCC address in the
message/answer transmitted. It is advised to enable this parameter when DLCC is a
Server for more than one Client in 2 way transmission. In this way the Host knows to
which Client the answer must be sent.
If receiving data from an RF device working in 1 way mode, DLCC (Server)
automatically includes the RF device address in the message to be sent to the Host.
If receiving data from an RF device working in 2 way mode, DLCC (Server)
automatically includes the RF device address in the message to be sent to the Host.
It is required to set the Host application to include the same address in the answer to
be transmitted back to the RF device.
