5.2.1 Solder Bridges
There are several solder-bridges on the backside of the i-PAN7, which modify how some
interfaces of the panel will function.
Solder Bridge
LB5, LB16
LB8
Trizeps IV/V and Trizeps VI/VII use different Ethernet-Phys.
Resistor R242 is in parallel to LB8. R242 or LB8 need to be closed for the
LB9
Pulls OTG_ID to GND.
Wether the USB-OTG port functions as host or slave depends on
software settings. One software setting is to determine this by the
OTG_ID pin. If it is pulled to GND, than the port functions as host,
otherwise it will work as USB slave.
LB14, LB15
Use the internal or external connector for the USB-OTG port.

USB-Slave Detect Signal to SODIMM-Pin 55.
Only close for Trizeps IV and V.
Enable 120R CAN termination.
LB13 is in parallel to resistor R118.
Connected to onboard CPLD.
May be used in a custom CPLD-program.
Default CPLD-program does not evaluate these signals.
Touch-Interrupt:
LB1: Touch-Interrupt routed to SODIMM-Pin 55
LB2: Touch-Interrupt routed to SODIMM-Pin 45
Close if HE910 modem is used.
Connects J10-4 to SODIMM-Pin 43
