6.2 Radio Command Set Summary
The Radio Commands allow the user to control the flow of data into and out of the radio as well as
initialization of the radio in API Serial Interface Mode 03.
Name Command Length Data Checksum
RF enable* 80H 0H 0H 80H
Send Data* 81H 1 to 7f0h (includes 802.3 Header) As required As Required
Send Data Complete* 82H 1H 0 or 1 (see 5.1.4) As Required
Received Data* 83H 1 to 7f0h (includes 802.3 Header) As Required As Required
In range* 84H 06H IEEE address of
Server Radio
As Required
Out of Range* 85H 0H 0H 85H
6.2.1 RF enable*
This command is issued from the Host processor to the Radio. The Radio must have this command
issued to it prior to any RF data transfers. This is a command with no data. Typically, this command is
issued to the Radio just after it has been brought out of reset. This enables the RF portion of the Radio and
turns the transmitter/receiver ON. This command requires an acknowledge.
6.2.2 Send data*
This command is issued by the Host to the Radio to send a data frame. The data frame here is the
actual frame that the transport/network protocol wants to send out. The data portion will be delivered to the
appropriate RF device. Broadcast frames will be delivered to all registered Client Radios without a RF data
link ACK. Broadcast frames are not required to reach all destinations. They are typically sent to everyone
at once.
