Connector Redirection
When the board is shipped the digital I/O pins are routed to a 10 pin Molex connector on the RTC battery
module.
The digital I/O interface is available through the Molex connector J2 (10 pins). An interface cable (open
ended) is deliverable from KONTRON (KAB-GPIO-PROTO-10, part number 62038).

Note:
1)
To protect the external power lines of peripheral devices make sure that
- the wires have the right diameter to withstand the maximum available current.
- the enclosure of the peripheral device fulfills the fire-protecting conditions of IEC/EN 60950.
