6.4 Bootloader
The Serinus Bootloader is the initial set of operations that the instruments’ microprocessor performs
when first powered up (similar to the BIOS found in a personal computer). This occurs every time the
instrument is powered up or during instrument resets. Once the instrument boots up, it will
automatically load the instruments’ firmware. A service technician may need to enter the Bootloader
to perform advanced microprocessor functions as described below.
To enter the Bootloader turn off the power to the instrument. Press and hold the plus key while
turning the power on. Hold the Plus key until the following screen appears.

This test is very useful for fault finding communication issues. It allows a communication test to be
carried out independent to any user settings or firmware revisions.
This command forces the following communication ports to output a string of characters: Serial Port
RS232 #1, USB rear and Ethernet Port. The default baud rate is 38400 for the RS232 Serial Port. To
initiate the test press the number 2 key from the Bootloader screen.
