Setting the Request ACKs Option | RF-Link Technology NL6000 specs

Refer to Section 5.6.1 for more information about each packet mode

Setting the Data Rate

1.Select Network ä Data Rate.

2.Select the data rate you want to use depending upon the bandwidth you occupy and your licenses. The available options are 12,000 bps and 22,050 bps.

Setting the Request ACKs Option

1.Select Network ä Request ACKs.

2.Select from the following options:

1-EnableWhen the modem sends data it requests an ACK from the destination modem. If it does not receive an ACK, the modem will retransmit up to the number of times you specify in the Max Retries option.

2-DisableWhen the modem sends data it does not request an ACK from the destination modem.

Setting the Contention Option

1.Select Network ä Contention.

2.Select from the following options:

1-NoneDo not use contention to determine when to transmit.

2-CSMAEnable Carrier Sense Multiple Access (CSMA) so that transmission waits until the channel is free of contention. This option is helpful if a units transmit and receive frequencies are the same.

Setting the Max Retries Option

You only need to set this parameter if the Request ACKs option is enabled. The system ignores this parameter if it is disabled.

1.Select Network ä Max Retries.

2.Enter the greatest number of times you want to retransmit if you do not receive an ACK response. The value must be in the range 1 9.
