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.
Low Power Mode
If “Low Power Mode” is selected, the module will disconnect the communications link and
shutdown its receiver circuits if the RS232 DTR signal goes to a low or reset state. When the
DTR signal becomes high or active, then the module will revert to normal operation.
Controlled Mode Options
For each controlled mode, there are
some options. In the “Advanced” page,
there are some timing parameters.
If you enter a “Link Check Time”, then
the master unit will send a “check
message” if the check time has elapsed
without any data transmissions. For
example, if you enter 10 seconds, then
if there is a 10 second period without a
data transmission, then the master
module will transmit a check message.
If the slave does not acknowledge, then
