Appendix A – Upgrading the Firmware
98
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.
Transferring KIT Files
The system will be non-operational during the upgrade procedure below.
The Firmware Transfers tool in NetLinx Studio is used to map KIT files to DXLink Transmitters and
Receivers. The instructions below assume that the preparations on the previous pages for an endpoint
system have been completed.
To send a KIT file to a Transmitter or Receiver:
1.
In NetLinx Studio from the Tools menu, select “Firmware Transfers > Send to NetLinx Device” to
open the Send to NetLinx Device dialog box.
2. Click Browse (...) to navigate to the target directory. The selected directory path is displayed in the
Location text box. KIT files in the target directory display under Files.
3. Select the appropriate KIT file from the list.
4. Enter the Device and System numbers for the target module in the Device and System text boxes.
5. Review the File, Connection, Address, and Target Device information for accuracy before you send.
