The update file contains both RCI (the Windows (tm) control software) and updated firmware for the TCB itself. The released version is the most recent fully-tested version and is recommended for most users. There may also be a beta version, which typically has new features but has not been fully tested. Beta versions are made available on the TCB-4 wiki site.
* Uninstall any previous versions of RCI. You may need administrative privileges to do this. Then select Start | Settings | Control Panel | Add/Remove Programs. When Windows finishes building the list of programs, select TCBx Remote Control Interface and press the Remove button.
* Download and install RCI on the support page. The download includes both updated RCI software to run on the computer and the corresponding update to the firmware that runs inside the TCB.
* Start RCI and connect to the TCB as usual. If the TCB is running old enough firmware (prior to V2.6.x), you will be automatically prompted to update its firmware. If the TCB is running an earlier version of the V2.6.x firmware, you will not be automatically prompted. You can still force an update by selecting Help | About and clicking on the Update Firmware button (you may want to note the existing firmware version number).
* When prompted to select the firmware file, you will need to navigate to the hard drive where RCI is installed, then to the following directory: C:\Program Files\TCBx\Remote\Firmware. Select the file you find there (tcb2.ezip, tcb3.elf or tcb4.elf) and click OK.
* The connection status window should appear and indicate that it is transferring the firmware. This usually takes several minutes, and may occasionally take as much as 15 minutes.
* When the file transfer is complete, the TCB will begin an automatic reset and RCI will attempt to reconnect to it. When the TCB has finished resetting, RCI should be able to reconnect, and the update is complete. The Help | About menu can be used to determine what the new firmware version number is.
