Firmware Upgrades
Firmware updates for both the gateway (ARM) and the built-in radio are possible over the
RS-232 debug interface using the SignalFire Toolkit, or over a remote TCP connection if an
Ethernet Gateway module is used.
Gateway (ARM) Firmware update steps
1 Open the SignalFire Toolkit application.
2 Open the correct COM port connected to the RS-232 port of the gateway.
3 Go to the Update menu and select Update Gateway Firmware.
4 The latest gateway firmware file will be selected by default.
5 Click Start Upgrade.
Gateway Radio Firmware update steps:
1 Open the SignalFire Toolkit application.
2 Open the correct COM port connected to the RS-232 port of the gateway.
3 Go to the Update menu and select Update Radio Firmware.
4 The latest radio firmware file will be selected by default.
5 Click Start Upgrade.
Rescue Gateway (ARM) Bootload
If in the process of a firmware update there is a power failure or other communications failure it may
be necessary to do a “rescue bootload.” If the base LED is solid on and/or the Toolkit is unable to
communicate with the Gateway the following process is necessary.
1 Remove DC power to the Gateway.
2 Open the SignalFire Toolkit application.
3 Open the correct COM port connected to the RS-232 port of the gateway.
4 Go to the Update menu and select Update Gateway Firmware.
5 The latest gateway firmware file will be selectable by default.
6 Click Start Upgrade.
7 Now re-connect the DC power to the gateway. The firmware update process should start. If the
firmware update does not start remove power for at least 10 seconds and re-try.
