•
in case the variable has an index, put the index number in (information box
”
Has Index“ is ticked and
”
Index“
box is editable);
•
set up required value of the variable into the
”
Value“ field. If the variable will be just read (checked its current
value), leave the field blank. Those variables, that have
”
Read only“ status (invariable constants, measured
values) will have the
”
Value” box uneditable;
•
by clicking on
”
Add“ button add a variable to the sequence of variables used for configuration.
Entering of a variable into the
”
Variables” window is depicted in the right part of the figure
Command
GET
(reading the current variable value),
SET
(setting up the required variable value), or
WALK
(reading the current status of all variables) will be done only for one chosen device from the list of devices in
”
RF
Address“
tab. Run the required command by clicking on relevant button in the top of the screen. After the click,
there will appear an information window in which a progress of getting/setting process of will be displayed. As the
individual settings are performed, the
”
tick” symbols in the
”
Done” box appear item-by-item. The
”
Getting/Setting”
window will disappear after the all commands of the sequence are being accomplished, or after the expiration of
the preset time limit (TimeOut). The current variable values are listed in the field
”
Value” in the relevant row.

To avoid serious mistakes that can bring the module into paralyzed condition, numb for further communication, it
is necessary to know the meaning of all modified variables of the device, including their mutual relations.
Example:
If value of
”
SLRF Test Flag” variable is set to ”1”, the module will be preset to send test messages in
period which is set up by variable
”
SLRF Test Timeout [ms]”. In this case the period is just 1 millisecond. The
trouble will occur if the test broadcasting would be switch on. It is necessary to set some reasonable period (e.g.
5 second) first and just then switch test broadcasting ”on”, otherwise the module would broadcast permanently and
never be able to receive any other command.
When configuring battery powered modules, always use the
”
Wake-On-Radio” (WOR) function. The function
enables to
”
wake up” the module with a special
”
waking” radio signal from
”
hibernation” mode (that means the
mode in which the module is almost permanently) to the mode of active signal reception. Keep in mind that by
”
waking up” of the particular required module the other modules, that are placed within the GateWay current
radio range, will also be activated. Excessive activating of the module can cause the reduction of its battery life. To
avoid the excessive
”
waking” of many modules around the GateWay it is recommended to follow these instructions:
- do not change the parameters if it is not necessary for the module’s functionality;
- consider the succession
of the configuration commands (or prepare them as a
”
template”);
- do not use command
”
WALK” if not
necessary - (reading of all module variables);
- find suitable place for the configuration, that is in a good reach
of configured device.
We also recommend keeping the modules in closed boxes, shielded with aluminum foil (or in metal boxes) so the
modules are protected from the excessive
”
waking up” and their batteries won’t be damaged. When you do the
preliminary configuration before mounting, always take out from the shielded box only the necessary number of
modules. After their configuration, the modules should be placed back in the shielded box.

USB-CMOS converter driver installation
If the computer operation system failed in automatic installing of the driver for the
”
USB-CMOS”, it is necessary
to install the driver manually. The relevant current driver can be found on a chip manufacturer’s (FTDI) webpages,
namely in the
”
VCP Drivers“ (Virtual COM Ports) section.
www.ftdichip.com/Drivers/VCP.htm
In the
”
Currently Supported VCP Drivers” table find a link to a driver relevant to your operating system. To
download the file, click on a link in the table. After downloading the file (in .ZIP format) into any directory in
your computer, unzip the file. It will create a new folder (directory) with a set of files (e.g.
”
CDM 2.08.24 WHQL
Certified”).
