Bootloader
The bootloader is a low-level version of the CHV-TSTATRF’s firmware that will
become active in the event an upload of the standard firmware fails. This lets you
perform some basic functions with the goal of getting the CHV-TSTATRF back to
normal operation.
If the CHV-TSTATRF goes into bootloader, the large seven-segment display will
show “Ld”, except when in Setup mode. All other LCD segments will be off. All
button presses will be ignored, except for the sequence which enters Setup mode
(refer to “Setup Mode” on page 18).
From the bootloader, Setup mode will support only the following functions:
• Check Firmware Version (rE)
• infiNET ID (id)
• infiNET RF Channel (Ch)
• Start infiNET Acquire (Ac)
• Unacquire Gateway (UA)
To restore functionality, try cycling power to the CHV-TSTATRF. If unit remains in
bootloader, you should resend the latest firmware using Crestron Toolbox.
