DL CORDLESS CARD™

If DLCC as Client, is transmitting to more than one destination device (see the three
Stargates in the following figure) in 2 way mode, it is necessary to set its Host
application to include the card address in the message to be transmitted to the
destination devices of the system. DLCC will include the same address in the answer
it receives from the destination devices and sends back to the Host.
Card Addr. + message
Card Addr. + answer

Figure 10 - Transmitting a Message in 2 Way Mode
The Address Stamping parameters consist of a 4-digit number in the range 0000-
1999.
NOTE
When the card receives data in 2 way mode from more than one RF
device, it is advised to enable Address Stamping for correct radio
transaction management.
NOTE
If communicating with only one RF device in 2 way mode, Address
Stamping is not required, since the data/answer generated by the
Host is only sent to that device. In this case
DLCC
can receive data
(messages) via radio only after sending the 2 way answer.
4.3.3 Address
Delimiter
The Address Delimiter allows a character to be included to separate the Address
stamping fields from the next fields in the message. Once enabled, it is required to
set the Host application to include the Address Delimiter character in the message.
Any character can be included in the hexadecimal range from 00 to FE.
