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 mode 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 mode, the large seven-segment display
will show “bL”, except when in SETUP mode (where “bL” identifies the Backlight
Timeout parameter). All other LDC 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
• Power Source (Po)
New firmware can be uploaded from the Crestron Toolbox.
