Appendix A – Upgrading the Firmware
108
Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver
Important Upgrade Information
Caution: Upgrading the firmware is a serious action in that if the upgrade fails, it can leave the
system completely non-operational.
In the Event of Power Loss During an Upgrade
If power loss occurs before any firmware information has been transferred – when power is restored, the
module will remain operational using the original firmware.
If power loss occurs after some of the firmware information has been transferred but before the transfer
is complete – when power is restored, the module will time out and will not operate until a successful
upgrade takes place.
Caution: If the application signals a failure, you must immediately reboot the Transmitter or
Receiver and attempt to upgrade the firmware again, as the module is in an unknown state and
cannot be guaranteed to be operational.
