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 STAR



Modem™ can

receive data (messages) via radio only after sending the 2 way

answer.

5.4.3 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.

5.5 RADIO PARAMETERS

5.5.1 RF Baud Rate (not for USA Model)

This parameter defines the baud rate used for radio communication. For

STARModem™ USA model the baud rate value is always set to 36800, while for

European models it can be set to 9600 or 19200 according to the device

communicating with STARModem™.

5.5.2 Transmission Mode (Client only)

STARModem™ Client can communicate within the system using two different

transmission modes:

• 1 way mode:

(default)

STARModem™ transmits data without requiring an

acknowledgement answer from the Remote Host (see par. 5.1

for details).

• 2 way mode:

STARModem™ transmits data requiring an acknowledgement

answer from the Remote Host (see par. 5.1 and par. 5.5.5 for

details). W

hen the destination device is connected to the

Remote Host through the Wedge Interface, it considers the

transmission successful after data has been sent. Therefore, an

Empty Answer is generated and passed back to the modem.
