Chapter Four Configuration
Page 35 © January 2011
Modifying an existing configuration
If you read a configuration from a module or a saved file, the program will display the
configuration parameters. You can change these parameters, and then program the module
and/or save the file.
4.4.1 Transparent Mode
The default setting of the program is
transparent mode. Select the system
address or use the random value
already selected - if the module is to
become part of an existing system,
then you must select the same system
address as the existing modules. Also
select the group address - only
modules with the same group address
will communicate with each other.
The “Go On-line On Startup” box
will normally be selected for
transparent mode. If you deselect
this, then the module will start-up in
command mode, and will not operate
until the host device sends it a AT
command to go on-line.
Transparent Repeater
When you select a transparent repeater, the program will ask you to enter a second group
address. The repeater will re-transmit messages from the first group to the second group - and
from the second group to the first
group.
A transparent repeater will transmit
data from its host device (if there is a
host connected) using the first group
address, and will only output data to
its host device if the received
message has the first group address.
If the transparent repeater receives a
message from the second group, it
will re-transmit the message but it
will not output the data.
4.4.2 Controlled Mode
If you select any of the controlled
mode options, you will be asked to
select a unit address for the module.
