The Development Kit Demonstration Software

The development kit includes software that is used to configure and control

the module through the Programming Dock. The software defaults to

the Advanced Configuration tab when opened (Figure 10). This window

configures the module’s settings.

1. Clicking the Contact Linx, Documentation and About labels on the

left side expands them to show additional information and links to the

latest documentation. This is shown in Figure 11.

2. The Help window shows tips and comments about the software.

3. The active module is connected to the PC and being configured by the

software.

4. Available modules are connected to the PC but are not currently being

configured or controlled by the software.

5. Known Modules are not currently connected to the PC, but have either

been connected to the software in the past or have been manually

entered.

6. The memory setting configures the software to read and write from

either volatile memory or non-volatile memory.

7. The Device Type section configures the module as either an Access

Point, End Device or Range Extender.

8. The Encryption Key box shows the module’s 16 byte AES encryption

key. This can only be read from modules configured as an AP.

9. The Address box shows the module’s current local address. The

Network ID is the identifier of the network that the module is in. No

other module with the same Network ID can have the same Address.

10. The Joined Modules list shows all of the modules that have joined

with the current module. An ED and RE are only joined with an AP, so

they have one entry. An AP can be joined to up to 50 other modules,

including up to 4 REs.

11. The Radio section configures the radio functions. The checkboxes

select which RF channels are used. The TX Power menu sets the

transmitter output power. The data rate menu sets the serial UART

data rate, which the module uses to configure the over-the-air data

rate. The RSSI Readback shows the RSSI value of the last good

packet that was received.

12. The GPIO Expander Type menus configure the eight GPIOs as digital

inputs, digital outputs or analog inputs. The digital inputs are also

configured to use internal pull-up or pull-down resistors, or set to

high-impedance. High impedance deactivates the internal resistors.

13. The Status column shows the current status of all of the GPIO lines on

the active module.

14. The Internal 20kohm radio button sets the internal resistors as either

pull-up or pull-down.

15. The module identity box shows the active module’s name, firmware

version and serial number.

16. The Read All button reads all of the values.

17. The Submit button writes all changes to the active module.

18. The Set Defaults button restores all settings to the factory defaults.
