Installation Guide
RC232-SA Spectrum Analyzer (SA) is a part of Radiocrafts’ RCTools PC suite tailored for use
with Radiocrafts’ RF Modules. For full installation procedure please read the RCTools
Installation Guide available at www.radiocrafts.com.
The SA requires access to the modules UART via an available COM-port together with
access to the modules CONFIG-pin. Typically UART-access is obtained via an UART-to-
RS232 or UART-to-USB converter. The Demo Boards (DB) from Radiocrafts contains
onboard level shifter for direct plug-in to a PC and further access to the related COM-port.
Screen Settings
It is recommended to run the application with screen size at least 1024x768 and font
resolution 96dpi.
Introduction
RC232 Spectrum Analyzer Tool, SA, enables you to easily scan all or a subset of channels
the module can operate on. For configuring, controlling test modes and sending messages,
please check the Configuration and Communication Tool, CCT.
Figure 1. Main window
Physically connect the DB, or your own hardware with the Radiocrafts module, to the COM-
port. If you are using the module on your own hardware, make sure to include the UART to
RS232 or UART to USB converter.

Start the program and the main window will look similar to what is shown in Figure 1.

Upper Toolbar Description
To connect to the module you need to press the connect button.
Before connecting, select the proper settings for your serial port:
name of an available communication port (COMx)
baud rate used to communicate with the module
After pressing connect button, the following message appears;
Figure 3. Waiting for prompt
The CONFIG pin on the module must then be pulled low. On Radiocrafts DB this is done by
pressing the CONFIG button. Program will wait 15 seconds for a prompt sign, which is sent
from the module when configuration mode is entered.
If you use an RTS-line to control the CONFIG line into the module, the program asserts RTS
low automatically. If you use RTS line for some other purpose, you can disable this feature
with the RTS Lock button.

When the configuration is loaded, you can see the modules name and number of available
channels.
Lower Toolbar Description
Threshold: By right-click and drag a threshold level will be visible on the screen (as a red
line) and the value of the threshold in dBm will be displayed in the toolbar. All RSSI-readings
above the threshold value will be marked dark blue for increased visibility.
Current: Current value. Show or hide latest scan and enables or disables smoothing on last
scan. The smoothing means reading RSSI and displaying average value of 3 or 5 readings
while remaining on the same channel (reduces the effect of rapid changes in the RSSI-value).
An RSSI reading is fast while changing channel takes longer time.
Average: Enables or disables displaying of the average value for last n scans, Average
values are shown in grey in the background and n can be selected and changed by the user,
default setting is 10.
Peakhold: Enables or disables view of peak value on each scanned channel.
Scan Limit: CTRL, left-click and drag over the bars for scanning only a selection of the
channels. It can be limited to one channel only for high-speed RSSI-readings during for
instance antenna tuning. The selected channel numbers are shown right to the Scan Limit
and whit white background behind the bars while the non-scanned bars have gets grey
background. The selected channels are reset to include all channels when right-clicking the
SCAN LIMIT button.
Information Box: Left-click on or above any bar will display a green cross. By
opening/clicking the Information Box to the right of the Lower Toolbar, all essential information
on this channel, regardless of the selection of buttons on the Toolbar, is displayed in a pop-up
window.
Miscellaneous
F9: Halt the scan. On some computers the graphics on the screen lag the RSSI-reading,
especially for RC2000 (83 channels). If so, halt the scan and release when the graphical
display of the bars on the screen has updated.
RC1040: No digital RSSI available, thus no valid information to be displayed with the SA tool.
RC2100: The digital reading reports RSSI of last received data package. As the SA tool
requires the modules to remain in configuration mode during the channel scan where no
reception of RF data packages is valid, the RC2100 provides no valid information for the SA
tool. Use the CCT program for monitoring RSSI on RC2100 for each selected channel and
read back RSSI when a valid data packet has been received.
Proximity effects: When monitoring an RF link between two modules in close range using
the SA Tool, you might observe increased RSSI-level on the neighboring channels to the
actual transmitting channel. This is due to RSSI detector saturation combined with adjacent
power always present in the neighboring channels.
