users can update the meter's operating software. This software can
include the bootloader, FPGA software (timing software for transit-

file. The updating procedure involves three steps:
1. Setting up the CTF878 in Flash Update mode.
2. Selecting the loading interface.
3. Loading the new software from the PC into the CTF878.

StartUp Guide or page 3-11 of the Programming
Manual). If both programs are to be replaced, install
the new bootloader first, before any other software.
