7 Boot
Start the CAN boot loader for a firmware
update via CAN
(High-active, connection to Ub during the
start-up of the motherboard)
Activity LED quickly blinks orange when
CAN bootloader is active

or threshold switch
9 UART_Rx Serial RS-232 interface Currently no use
10 UART_Tx
For the startup of the PCAN-MicroMod FD Digital 1/2 it is sufficient to connect a
voltage source to pins 1 und 2. The configuration of the PCAN-MicroMod FD Digital
1/2 is done viar the CAN bus being connected to pins 3 and 4. Read more in 5 Config-
uration Software on page15.
