On-Board Jumpers
Most options on the C23-SATA are stuffing options, so there are only 2 jumpers which are available
for user interaction, J-RES (force reset) and J-FWH2 (select Firmware Hub).
J-RES
Provided as an option, the pin header J-RES can be used for resetting the CPU host board (processor
reset) if wired to additional circuitry (e.g. watchdog or manual pushbutton). Tie reset# to GND with
an open collector output. While debugging the system, a 2.54mm jumper may be used to force a
manual reset.
J-FWH2
Selection of BIOS to boot from. Please see description in chapter 'Firmware Hub 2'.
J-SER
COM-A mode select RS-232 - RS-485. Please refer to detailed description in chapter 'COM-A' front
panel connector.
J-TRM1 J-TRM2
On-Board line termination transmit/receive RS-485. Please refer to detailed description in chapter
'COM-A' front panel connector.
J-RES
