2.1.4 Updating CTF878 Software
By using a Windows-based PC with an RS232 connection, CTF878 users can update the meter’s operating software.
This software can include the bootloader, FPGA software (timing software for transit-time), instrument software, the
meter string file and the Help string 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.
CAUTION!
To guard against mishap, you should print out, download or otherwise record all logs, settings and
other data you wish to save.
IMPORTANT: When uploading new software, the CTF878 uses a “bootloader” program. Be sure the software you are
installing is compatible with the installed bootloader version (see The About Option on page 4-11 of the
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.
