LOCALIZED PACKETS
Local packets are packets sent between the remote/base device and the radio
modules. These are used to setup the radio for a connection or to determine
radio link diagnostics. All localized packets are in the format shown in Figure 2.
To Radio Module, CMD Bytes:
0x80 – Slave connect, sends 2 DATA words, low order byte first, (SRC
word, a DEST word.) Places the radio into a slave connect state based on
the hop group selected by the defined ID set (SRC and DEST.) SRC is the
slave ID and DEST is the master ID. Once executed, the radio sends out a
packet containing the ID set and the next channel of operation. It then
waits for a reply from the master radio. If a reply is received without error,
a connection state is set within the slave radio and data transmission can
begin between the master and slave hosts.
Pin 3 on the connector must be pulled low for this command to be
accepted and executed. Otherwise, it is ignored.
Slave radio acknowledges command with a Slave Connect Acknowledgement message
(0x80). This message is ignored when radio-state is Test Mode. When sent during a
connection, this command results in the connection being dropped and a new acquisition
sequence started.
0x81 – Master dwell, sends 2 DATA words, low order byte first, (SRC
word, a DEST word) from base
0x82 – Sleep, (Remote) commands the radio to power down
0x83 – Status request
0x84 – Software version request
0x85 – Test Mode, Enable/Disable - sends 5 DATA bytes
0x86 – Homeowner ID - sends 1 DATA byte (homeowner id - 0 to 63)
0x87 – Test Mode, Set skip - sends 3 DATA bytes ('S', 'K', n= #of packets
to skip)
0x88 – Reserved
