Vendor ID
This command is used to set the Vendor ID in the radios. The Vendor ID is a one-time writable parameter which
is not able to be read back for security purposes. Radios with the Vendor ID set only communicate to other
radios that have Vendor ID set to the same value. Once the Vendor ID is set it cannot be changed. Setting this
value incorrectly results in a radio which is not able to communicate with other radios on the network. Setting
the Vendor ID is not necessary for the radios to operate and care should be taken when using it. To see if the
Vendor ID has been set the OEM can issue the command <0xCC> <0xF2> <0x06> <0xFF> <0xFF>. If the response
is 0xFF 0xFF then VID has not been set. If the response is 0x00 0x00 then the VID has been set. Issuing the
command <0xCC> <0xF2> <0x06> <0xFF> <0xFF> will not set the Vendor ID.

Overview

The active firmware running on the module may be upgraded via the serial interface. The Windows OEM
Configuration Utility v5.07 and above can perform this operation for modules with access to a PC, but for
embedded applications it may be necessary for the OEM to program the FW upgrade through a microcontroller.
Upgrade of the FW over the air is not supported on the RM024. The firmware upgrade procedure will not affect
the radio EEPROM settings except to update the version number.

Upgrading Via Windows OEM Configuration Utility

Upgrading through the OEM Configuration Utility is a straight-forward process. The PC Settings tab has an option
when the RM024 is the selected product to perform a Radio Firmware Update. This section of the OEM software
can be used to upgrade the FW of the radio connected to Port 1 of the software.
To perform a firmware upgrade, follow these steps (illustrated in
1. Connect the Development Kit or other interface board with the RM024 to the PC.
2. Select Find Ports, then select the appropriate Windows Comm Port from the drop-down menu.
Note: If the appropriate port doesn't appear, click Add Ports to add the port manually, then repeat
step 2.
3. Set the correct settings for the radio in Port 1. By default this is 115,200-8-N-1 with Hardware
Handshaking enabled.
4. Verify that the Port Status in Port 1 is Open.
5. In the Radio Firmware Upgrade box, select Firmware Upgrade.
6. In the Open File Window, select the appropriate RM024 FW binaries.
7. When the download is successful, a success window appears and the new firmware is now active.
