Page 3: Introduction
Point-to-Point/SIK Firmware User Manual www.rfdesign.com.au 1 Introduction The RFD900x/ux/ux-SMT and RFD868x/ux/ux-SMT can be loaded with three official firmware releases to achieve different communication architectures and node topologies. Available firmware types are: Point-to-Point/SiK Asynchronous mesh Multipoint network This document describes the configuration of the Point-to-Point/SiK V3.x and up. Modems sold after April 2019 come with a 3.xx version loaded by default. -
Page 4: Peer-To-Peer Network
Point-to-Point/SIK Firmware User Manual www.rfdesign.com.au 2 Peer-to-peer Network The peer-to-peer firmware offers straight forward data communication between two nodes. Figure 4-2 depicts this very simple communication topology. Whenever two nodes have compatible parameters and are within range, communication will be established after the units synchronise. A solid green LED state indicates synchronisation has been successful. -
Page 5: Software/Gcs Support
This firmware is a development of the open source project called “SiK” that was created by Mike Smith and further developed and modified by Andrew Tridgell and RFDesign. The modems feature a boot loader to facilitate field upgrade of the modem firmware via the serial port. -
Page 6: Configuration Of Settings
Point-to-Point/SIK Firmware User Manual www.rfdesign.com.au 4 Configuration of Settings The RFD x and ux series modems can be configured in two main ways. The use of a GUI tool and using AT modem commands by serial terminal. 4.1 GUI There are a number of graphical ways to modify the settings of x series modems using the peer to peer firmware including the SiK Radio tab under Optional Hardware in Mission Planner and the RFD900 Tools available from the RFD website (see useful links). -
Page 7: At Commands
Point-to-Point/SIK Firmware User Manual www.rfdesign.com.au 4.2 AT Commands The AT command mode can be entered by using the ‘+++’, without quotes, sequence in a serial terminal connected to the radio. You should allow at least one second after the sending of data before entering the sequence to ensure that the modem will correctly enter command mode. - Page 8 Table 4-1: AT Commands and their description An example that command will return the local modem’s firmware version string.

Page 13: At Commands Examples
Point-to-Point/SIK Firmware User Manual www.rfdesign.com.au 4.3 AT Commands Examples Encryption The 128/256 bit AES data encryption may be set, enabled or disabled using the AT commands (see Table 4.1). The encryption key can be any 32/64 character hexadecimal string. First enter AT command mode by typing ‘+++’ and waiting for a moment till an ‘OK’ from the modem. - Page 14 Point-to-Point/SIK Firmware User Manual www.rfdesign.com.au To enable PPM control signal pass through on a modem link it is necessary to set the ground station modem to PPM input and the receiver modem to PPM output. This is enabled using the S registers 16 or 17.

Page 15: Region Certified Modems
5.1 Frequency band example FCC-compliant radios, designated as RFD900x-US, are allowed to operate in two different frequency bands. The user might operate two pairs of radio simultaneously without them interfering with each other – given a minimal physical distance between the radios is respected – while remaining FCC- compliant by setting each pair to a different frequency band. -
