This should be a unique address for that module (1 – 127).
Auto-Connect Master
In auto-connect mode, the “master”
will automatically attempt to connect to
the slave address. Once connected, the
link can transfer data in either
direction, with error-checking,
acknowledgement messages, and
automatic re-transmissions if
necessary. If the link connection fails
(indicated by the DCD led), then the
master unit will automatically try to
reconnect to the slave.
At the master unit, you need to enter
the address of the slave. Select the
“Stored Add” page and “Dest1”. The
address of the slave is entered into
“Dest Add 1” and up to five repeater
addresses may be entered. Repeater
modules may be configured in any
controlled mode option, but they must
have the same system address. The
repeater addresses are entered in order
from the master - that is, “Rpt 1” is the first repeater after the master.
You can enter address structures for four slaves - “Dest 1” to “Dest 4”. However the host must
use AT command to select which slave is required. Without the use of AT commands, the
master will only attempt to connect to the address configured in “Dest 1”.
Auto-Connect Slave
The only configuration required for a
auto-connect slave module is to enter
its unit address.
Single-Connect
In single-connect controlled mode, the
host devices use AT commands to
select destination addresses to connect
to. Normally the only configuration
required is a unit address.
Fast Operation
“Fast operation” can be used for any
controlled mode, however it must be
selected for each module. It is
normally used for auto-connect,
