Preparing for KIT File Transfers

To prepare for KIT file transfers:

Check to be sure #3 Toggle on the bottom of the Transmitter or Receiver is set to ON.

2. Verify that you have the latest version of NetLinx Studio on your PC.

If the version is not the latest –

Use the Web Update option in NetLinx Studio’s Help menu to obtain the latest version.

Go to www.amx.com and login as a Dealer to download the latest version.

3. Download the latest Firmware (KIT) file from www.amx.com on the DXLink Transmitter or Receiver product page

to your PC. (Place KIT files on a local drive for speedy throughput.)

4. Verify the following:

a. Verify that an Ethernet/RJ-45 cable is connected from the switcher’s integrated Master to the network

(e.g., from the LAN 100/1000 port on an Enova DGX 32 to a LAN).

b. Verify that the target Transmitter or Receiver is connected via its DXLink connector to a DXLink Input or

Output Board (respectively) on the switcher.

c. Verify that the switcher is powered on.

5. Launch NetLinx Studio and open the OnLine Tree.

6. Bind the target Transmitter or Receiver to the integrated Master: select and right-click the TX or RX; from the

context sensitive menu, select Network Bind/Unbind Device (be sure the check box is selected); click OK.

7. Determine the Device Number assigned to the target Transmitter or Receiver when it was bound. For the Device

Number location, see FIG. 40 on page 103. The Transmitter or Receiver is ready for the KIT file transfer.

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.
